It has the ability to drive up to 150 W. (1) Stereo into 4 speakers from a single 36V supply. PurePathTM HD technology enables traditional AB-Amplifier performance (<0.03% THD) levels while providing the power efficiency of traditional class D amplifiers. Unlike traditional Class-D amplifiers, the distortion curve only increases once the output levels move into clipping. PurePathTM HD technology enables lower idle losses making the device even more efficient.

(70m) is recommended for use with the TAS5613A. The use of this material can provide for higher power output, improved thermal performance, and better EMI margin (due to lower PCB trace inductance. PVDD CAPACITOR RECOMMENDATION The large capacitors used in conjunction with each full-bridge, are referred to as the PVDD Capacitors. These capacitors should be selected for proper voltage margin and adequate capacitance to support the power requirements. In practice, with a well designed system power supply, 1000 F, 50V will support more applications. The PVDD capacitors should be low ESR type because they are used in a circuit associated with high-speed switching. DECOUPLING CAPACITOR RECOMMENDATIONS In order to design an amplifier that has robust performance, passes regulatory requirements, and exhibits good audio performance, good quality decoupling capacitors should be used. In practice, X7R should be used in this application. The voltage of the decoupling capacitors should be selected in accordance with good design practices. Temperature, ripple current, and voltage overshoot must be considered. This fact is particularly true in the selection of the 2F that is placed on the power supply to each half-bridge. It must withstand the voltage overshoot of the PWM switching, the heat generated by the amplifier during high power output, and the ripple current created by high power output. A minimum voltage rating of 50V is required for use with a 36V power supply.

Typical Differential (2N) PBTL Application With BD Modulation Filters Submit Documentation Feedback 17 TAS5613A SLAS711B - JUNE 2010 - REVISED SEPTEMBER 2011 www.ti.com THEORY OF OPERATION POWER SUPPLIES To facilitate system design, the TAS5613A needs only a 12V supply in addition to the (typical) 36V power-stage supply. An internal voltage regulator provides suitable voltage levels for the digital and low-voltage analog circuitry. Additionally, all circuitry requiring a floating voltage supply, e.g., the high-side gate drive, is accommodated by built-in bootstrap circuitry requiring only an external capacitor for each half-bridge. In order to provide outstanding electrical and acoustical characteristics, the PWM signal path including gate drive and output stage is designed as identical, independent half-bridges. For this reason, each half-bridge has separate bootstrap pins (BST_X), and power-stage supply pins (PVDD_X). Gate drive supply (GVDD_X) is separate for each half bridge for the PHD package and separate per full bridge for the DKD package. Furthermore, an additional pin (VDD) is provided as supply for all common circuits. Although supplied from the same 12V source, separating to GVDD_A, GVDD_B, GVDD_C, GVDD_D, and VDD on the printed-circuit board (PCB) by RC filters (see application diagram for details) is recommended. These RC filters provide the recommended high-frequency isolation. Special attention should be paid to placing all decoupling capacitors as close to their associated pins as possible. In general, inductance between the power supply pins and decoupling capacitors must be avoided. (See reference board documentation for additional information.) For a properly functioning bootstrap circuit, a small ceramic capacitor must be connected from each bootstrap pin (BST_X) to the power-stage output pin (OUT_X). When the power-stage output is low, the bootstrap capacitor is charged through an internal diode connected between the gate-drive power-supply pin (GVDD_X) and the bootstrap pins. When the power-stage output is high, the bootstrap capacitor potential is shifted above the output potential and thus provides a suitable voltage supply for the high-side gate driver. In an application with PWM switching frequencies in the range from 300kHz to 400kHz, it is recommended to use 33nF ceramic capacitors, size 0603 or 0805, for the bootstrap supply. These 33nF capacitors ensure sufficient energy storage, even during minimal PWM duty cycles, to keep the high-side power stage FET (LDMOS) fully turned on during the remaining part of the PWM cycle. Special attention should be paid to the power-stage power supply; this includes component selection, PCB placement, and routing. As indicated, each half-bridge has independent power-stage supply pins (PVDD_X). For optimal electrical performance, EMI compliance, and system reliability, it is important that each PVDD_X pin is decoupled with a 2-F ceramic capacitor placed as close as possible to each supply pin. It is recommended to follow the PCB layout of the TAS5613A reference design. For additional information on recommended power supply and required components, see the application diagrams in this data sheet. The 12V supply should be from a low-noise, low-output-impedance voltage regulator. Likewise, the 36V power-stage supply is assumed to have low output impedance and low noise. The power-supply sequence is not critical as facilitated by the internal power-on-reset circuit. Moreover, the TAS5613A is fully protected against erroneous power-stage turn on due to parasitic gate charging. Thus, voltage-supply ramp rates (dV/dt) are non-critical within the specified range (see the Recommended Operating Conditions table of this data sheet). SYSTEM POWER-UP/POWER-DOWN SEQUENCE Powering Up The TAS5613A does not require a power-up sequence. The outputs of the H-bridges remain in a high-impedance state until the gate-drive supply voltage (GVDD_X) and VDD voltage are above the undervoltage protection (UVP) voltage threshold (see the Electrical Characteristics table of this data sheet). Although not specifically required, it is recommended to hold RESET in a low state while powering up the device. This allows an internal circuit to charge the external bootstrap capacitors by enabling a weak pulldown of the half-bridge output. Powering Down The TAS5613A does not require a power-down sequence. The device remains fully operational as long as the gate-drive supply (GVDD_X) voltage and VDD voltage are above the undervoltage protection (UVP) voltage threshold (see the Electrical Characteristics table of this data sheet). Although not specifically required, it is a good practice to hold RESET low during power down, thus preventing audible artifacts including pops or clicks. 18 Submit Documentation Feedback Copyright (c) 2010-2011, Texas Instruments Incorporated Product Folder Link(s): TAS5613A TAS5613A SLAS711B - JUNE 2010 - REVISED SEPTEMBER 2011 www.ti.com ERROR REPORTING The SD, OTW, OTW1 and OTW2 pins are active-low, open-drain outputs. The function is for protection-mode signaling to a PWM controller or other system-control device. Any fault resulting in device shutdown is signaled by the SD pin going low. Also, OTW and OTW2 go low when the device junction temperature exceeds 125C, and OTW1 goes low when the junction temperature exceeds 100C (seeTable 2). Table 2. Error Reporting SD OTW1 OTW2, OTW DESCRIPTION 0 0 0 Overtemperature (OTE) or overload (OLP) or undervoltage (UVP) Junction temperature higher than 125C (overtemperature warning) 0 0 1 Overload (OLP) or undervoltage (UVP). Junction temperature higher than 100C (overtemperature warning) 0 1 1 Overload (OLP) or undervoltage (UVP). Junction temperature lower than 100C 1 0 0 Junction temperature higher than 125C (overtemperature warning) 1 0 1 Junction temperature higher than 100C (overtemperature warning) 1 1 1 Junction temperature lower than 100C and no OLP or UVP faults (normal operation) Note that asserting either RESET low forces the SD signal high, independent of faults being present. TI recommends monitoring the OTW signal using the system microcontroller and responding to an overtemperature warning signal by, e.g., turning down the volume to prevent further heating of the device resulting in device shutdown (OTE). To reduce external component count, an internal pullup resistor to 3.3V is provided on both SD and OTW outputs. Level compliance for 5V logic can be obtained by adding external pullup resistors to 5 V (see the Electrical Characteristics section of this data sheet for further specifications). DEVICE PROTECTION SYSTEM The TAS5613A contains advanced protection circuitry carefully designed to facilitate system integration and ease of use, as well as to safeguard the device from permanent failure due to a wide range of fault conditions such as short circuits, overload, overtemperature, and undervoltage. The TAS5613A responds to a fault by immediately setting the power stage in a high-impedance (Hi-Z) state and asserting the SD pin low. In situations other than overload and overtemperature error (OTE), the device automatically recovers when the fault condition has been removed, i.e., the supply voltage has increased. The device will function on errors, as shown in Table 3. Table 3.

PIN-TO-PIN SHORT CIRCUIT PROTECTION (PPSC) The PPSC detection system protects the device from permanent damage in the case that a power output pin (OUT_X) is shorted to GND_X or PVDD_X. For comparison, the OC protection system detects an overcurrent after the demodulation filter where PPSC detects shorts directly at the pin before the filter. PPSC detection is performed at startup i.e. when VDD is supplied, consequently a short to either GND_X or PVDD_X after system startup will not activate the PPSC detection system. When PPSC detection is activated by a short on the output, all half bridges are kept in a Hi-Z state until the short is removed, the device then continues the startup sequence Submit Documentation Feedback Copyright (c) 2010-2011, Texas Instruments Incorporated Product Folder Link(s): TAS5613A 19 TAS5613A SLAS711B - JUNE 2010 - REVISED SEPTEMBER 2011 www.ti.com and starts switching. The detection is controlled globally by a two step sequence. The first step ensures that there are no shorts from OUT_X to GND_X, the second step tests that there are no shorts from OUT_X to PVDD_X. The total duration of this process is roughly proportional to the capacitance of the output LC filter. The typical duration is < 15ms/F. While the PPSC detection is in progress, SD is kept low, and the device will not react to changes applied to the RESET pins. If no shorts are present the PPSC detection passes, and SD is released. A device reset will not start a new PPSC detection. PPSC detection is enabled in BTL and PBTL output configurations, the detection is not performed in SE mode. To make sure not to trip the PPSC detection system it is recommended not to insert resistive load to GND_X or PVDD_X. OVERTEMPERATURE PROTECTION PHD Package The TAS5613A PHD package option has a three-level temperature-protection system that asserts an active-low warning signal (OTW1) when the device junction temperature exceeds 100C (typical), (OTW2) when the device junction temperature exceeds 125C (typical) and, if the device junction temperature exceeds 155C (typical), the device is put into thermal shutdown, resulting in all half-bridge outputs being set in the high-impedance (Hi-Z) state and SD being asserted low. OTE is latched in this case. To clear the OTE latch, RESET must be asserted. Thereafter, the device resumes normal operation. DKD Package The TAS5613A DKD package option has a two-level temperature-protection system that asserts an active-low warning signal (OTW) when the device junction temperature exceeds 125C (typical) and, if the device junction temperature exceeds 155C (typical), the device is put into thermal shutdown, resulting in all half-bridge outputs being set in the high-impedance (Hi-Z) state and SD being asserted low. OTE is latched in this case. To clear the OTE latch, RESET must be asserted. Thereafter, the device resumes normal operation. UNDERVOLTAGE PROTECTION (UVP) AND POWER-ON RESET (POR) The UVP and POR circuits of the TAS5613A fully protect the device in any power-up/down and brownout situation. While powering up, the POR circuit resets the overload circuit (OLP) and ensures that all circuits are fully operational when the GVDD_X and VDD supply voltages reach stated in the Electrical Characteristics table. Although GVDD_X and VDD are independently monitored, a supply voltage drop below the UVP threshold on any VDD or GVDD_X pin results in all half-bridge outputs immediately being set in the high-impedance (Hi-Z) state and SD being asserted low. The device automatically resumes operation when all supply voltages have increased above the UVP threshold. DEVICE RESET When RESET is asserted low, all power-stage FETs in the four half-bridges are forced into a high-impedance (Hi-Z) state. In BTL modes, to accommodate bootstrap charging prior to switching start, asserting the reset input low enables weak pulldown of the half-bridge outputs. In the SE mode, the output is forced into a high impedance state when asserting the reset input low. Asserting reset input low removes any fault information to be signalled on the SD output, i.e., SD is forced high. A rising-edge transition on reset input allows the device to resume operation after an overload fault. To ensure thermal reliability, the rising edge of reset must occur no sooner than 4 ms after the falling edge of SD. SYSTEM DESIGN CONSIDERATION A rising-edge transition on reset input allows the device to execute the startup sequence and starts switching. Apply only audio when the state of READY is high that will start and stop the amplifier without having audible artifacts that is heard in the output transducers. The CLIP signal is indicating that the output is approaching clipping. The signal can be used to either an audio volume decrease or intelligent power supply controlling a low and a high rail. The device is inverting the audio signal from input to output. The VREG pin is not recommended to be used as a voltage source for external circuitry. 20 Submit Documentation Feedback Copyright (c) 2010-2011, Texas Instruments Incorporated Product Folder Link(s): TAS5613A TAS5613A SLAS711B - JUNE 2010 - REVISED SEPTEMBER 2011 www.ti.com OSCILLATOR The oscillator frequency can be trimmed by external control of the FREQ_ADJ pin. To reduce interference problems while using radio receiver tuned within the AM band, the switching frequency can be changed from nominal to lower values. These values should be chosen such that the nominal and the lower value switching frequencies together results in the fewest cases of interference throughout the AM band. can be selected by the value of the FREQ_ADJ resistor connected to AGND in master mode. For slave mode operation, turn of the oscillator by pulling the FREQ_ADJ pin to VREG. This configures the OSC_I/O pins as inputs and needs to be slaved from an external differential clock. PRINTED CIRCUIT BOARD RECOMMENDATION Use an unbroken ground plane to have good low impedance and inductance return path to the power supply for power and audio signals. PCB layout, audio performance and EMI are linked closely together. The circuit contains high fast switching currents; therefore, care must be taken to prevent damaging voltage spikes. Routing the audio input should be kept short and together with the accompanied audio source ground. A local ground area underneath the device is important to keep solid to minimize ground bounce. Netlist for this printed circuit board is generated from the schematic in Figure 12. Note T1: PVDD decoupling bulk capacitors C60-C64 should be as close as possible to the PVDD and GND_X pins, the heat sink sets the distance. Wide traces should be routed on the top layer with direct connection to the pins and without going through vias. No vias or traces should be blocking the current path. Note T2: Close decoupling of PVDD with low impedance X7R ceramic capacitors is placed under the heat sink and close to the pins. Note T3: Heat sink needs to have a good connection to PCB ground.

TI and TI suppliers consider certain information to be proprietary, and thus CAS numbers and other limited information may not be available for release.

Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All semiconductor products (also referred to herein as "components") are sold subject to TI's terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI's terms and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily performed. TI assumes no liability for applications assistance or the design of Buyers' products. Buyers are responsible for their products and applications using TI components. To minimize the risks associated with Buyers' products and applications, Buyers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional restrictions. Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use of any TI components in safety-critical applications. In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI's goal is to help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and requirements. Nonetheless, such components are subject to these terms. No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties have executed a special agreement specifically governing such use. Only those TI components which TI has specifically designated as military grade or "enhanced plastic" are designed and intended for use in military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such components to meet such requirements.
