Si8239x Data Sheet

4.0 A ISODrivers with 2.5 V VDDI and Safety Features

The Si8239x combines two isolated drivers with either an independent input control or a

single input into a single package for high power applications. All drivers operate with a

2.5 V input VDD and a maximum drive supply voltage of 24 V.

The Si8239x isolators are ideal for driving power MOSFETs and IGBTs used in a wide

variety of switched power and motor control applications. These drivers utilize Silicon

Laboratories' proprietary silicon isolation technology, supporting up to 5 kVRMS with-

stand voltage. This technology enables high CMTI (100 kV/µs), lower prop delays and

skew, reduced variation with temperature and age and tighter part-to-part matching.

It also offers some unique features such as an output UVLO fault detection and feed-

back, and automatic shutdown for both drivers, an EN (active high) pin, a safe delayed

start-up time of 1 ms, fail-safe drivers with default low in case of VDDI power-down, and

dead time programmability. The Si8239x family offers longer service life and dramatical-

ly higher reliability compared to opto-coupled gate drivers.

Automotive Grade is available for certain part numbers. These products are built using

automotive-specific flows at all steps in the manufacturing process to ensure the robust-

ness and low defectivity required for automotive applications.

2. System Overview

The operation of an Si8239x channel is analogous to that of an optocoupler and gate driver, except an RF carrier is modulated instead

of light. This simple architecture provides a robust isolated data path and requires no special considerations or initialization at start-up.

A simplified block diagram for a single Si8239x channel is shown in the following figure.

Figure 2.1. Simplified Channel Diagram

A channel consists of an RF Transmitter and RF Receiver separated by a semiconductor-based isolation barrier. Referring to the

Transmitter, input A modulates the carrier provided by an RF oscillator using on/off keying. The Receiver contains a demodulator that

decodes the input state according to its RF energy content and applies the result to output B via the output driver. This RF on/off keying

scheme is superior to pulse code schemes as it provides best-in-class noise immunity, low power consumption, and better immunity to

magnetic fields. See the following figure for more details.

2.3 Power Supply Connections

Isolation requirements mandate separating VDDI from the driver supplies. The decoupling caps for these supplies must be placed as

close to the VDD and GND pins of the Si8239x as possible. The optimum values for these capacitors are 1 μF and 0.1 μF for VDDI and

10 μF and 0.1 μF for each driver supply. Low effective series resistance (ESR) capacitors, such as Tantalum, are recommended.

Si8239x Data Sheet

System Overview

silabs.com | Building a more connected world. Rev. 1.01 | 11

2.4 Power Dissipation Considerations

Proper system design must assure that the Si8239x operates within safe thermal limits across the entire load range. The Si8239x total

power dissipation is the sum of the power dissipated by bias supply current, internal parasitic switching losses, and power dissipated by

the series gate resistor and load. Equation 1 shows Si8239x power dissipation.

PD=VDDI *IDDI +2*VDD2*IDD2+f*CL*VDD2

(

Rp+Rg

)

+f*CL*VDD2

(

Rn+Rg

)

+ 2 * f*Cint *VDD2

Equation 1.

Note: Where:

•PD is the total Si8239x device power dissipation (W)

• IDDI is the input side maximum bias current (from table 4.1, 3.8 mA)

• IDD2 is the driver side maximum bias current (from table 4.1, 6.5 mA)

• Cint is the internal parasitic capacitance (370 pf)

• VDDI is the input side VDD supply voltage (2.5 V to 5. 5V)

• VDD2 is the driver side supply voltage (10 V to 24 V)

• f is the switching frequency (Hz)

• CL is the load capacitance (F)

• RG is the external gate resistor (Ω)

• RP is the RDS(ON) of the driver pull-up device (2.7 Ω)

• Rn is the RDS(ON) of the driver pull-down device (1 Ω)

Example calculation (using IDDx values from Table 4.1 for Si82397)

VDDI = 5 V

VDD2 = 12 V

f = 350 kHz

RG = 22 Ω

CL = 2 nF

PD = 0.123 W is the total dissipated power by the Si8239x package.

From this, the driver junction temperature can be calculated using Equation 2.

Tj=TA+PD*θja

Equation 2.

Note: Where:

•Tj is the junction temperature (°C)

• TA is the ambient temperature (°C)

• PD is the power dissipated in the package (W)

• Θja is the thermal resistance of the package (100 °C/W from table 4.7)

For this example, assume that TA is 25 °C.

Tj= 25 + 0.123 * 100

Si8239x Data Sheet

System Overview

silabs.com | Building a more connected world. Rev. 1.01 | 12

Tj is 37.3 °C.

Equation 2 can be rearranged to determine the maximum package power dissipation for a given ambient temperature.

PDmax =

(

Tjmax −TA

θja

)

Note: Where:

• PDmax is the maximum allowed power dissipation (W)

• Tjmax is the maximum allowed junction temperature (150 °C from table 4.8)

• TA is the ambient temperature (25 °C in this example)

• Θja is the thermal resistance of the package (100 °C/W from table 4.7)

PDmax = 1.25 W

Substituting values used in this example back into Equation 1, establishes a relationship between the maximum capacitive load and

switching frequency.

The following figure shows the relationship between the capacitive load and the switching frequency for four different driver supply vol-

tages. In the figure, the points along the load line represent the package dissipation-limited value of CL as a function of switching fre-

quency.

Figure 2.15. Max Load vs. Switching Frequency

2.5 Layout Considerations

It is most important to minimize ringing in the drive path and noise on the Si8239x VDD lines. Care must be taken to minimize parasitic

inductance in these paths by locating the Si8239x as close to the device it is driving as possible. In addition, the VDD supply and

ground trace paths must be kept short. For this reason, the use of power and ground planes is highly recommended. A split ground

plane system having separate ground and VDD planes for power devices and small signal components provides the best overall noise

performance.

2.6 Undervoltage Lockout Operation

Device behavior during start-up, normal operation and shutdown is shown in Figure 2.16 Si82391/2/3/6/8 Device Behavior during Nor-

mal Operation and Shutdown on page 15, where UVLO+ and UVLO- are the positive-going and negative-going thresholds respective-

ly. Note that outputs VOA and VOB default low when input side power supply (VDDI) is not present.

Si8239x Data Sheet

System Overview

silabs.com | Building a more connected world. Rev. 1.01 | 13

2.6.1 Device Startup

Outputs VOA and VOB are held low during power-up until VDD is above the UVLO threshold for time period tSTART. Following this,

the outputs follow the states of inputs VIA and VIB.

Si8239x Data Sheet

System Overview

silabs.com | Building a more connected world. Rev. 1.01 | 14

2.6.2 Undervoltage Lockout

Undervoltage Lockout (UVLO) is provided to prevent erroneous operation during device startup and shutdown or when VDD is below its

specified operating circuits range. The input (control) side, Driver A and Driver B, each have their own undervoltage lockout monitors.

The Si8239x input side enters UVLO when VDDI < VDDIUV–, and exits UVLO when VDDI > VDDIUV+. The driver outputs, VOA and

VOB, remain low when the input side of the Si8239x is in UVLO and their respective VDD supply (VDDA, VDDB) is within tolerance.

Each driver output can enter or exit UVLO independently for the Si82394/5/6/7/8 products. For example, VOA unconditionally enters

UVLO when VDDA falls below VDDAUV– and exits UVLO when VDDA rises above VDDAUV+. For the Si82390/1/3 products, when

either VDDA or VDDB falls under VDDxUV–, this information is fed back through the isolation barrier to the input side logic which forces

VOB or VOA to be driven low respectively under these conditions. If the application is driving a transformer for an isolated power con-

verter, for example, this behavior is useful to prevent flux imbalances in the transformer. Please note that this feature implies that it can

only be implemented when the VDDA and VDDB power supplies are independent from each other. If a bootstrap circuit is used for

Si82390/1/3, it will prevent the IC from powering up. Do not use the Si82390/1/3 in conjunction with a bootstrap circuit for driver power.

Figure 2.17. Si82390/4/5/7 Device Behavior during Normal Operation and Shutdown

2.6.3 Control Inputs

VIA, VIB, and PWM inputs are high-true, TTL level-compatible logic inputs. A logic high signal on VIA or VIB causes the corresponding

output to go high. For PWM input versions (Si82394/8), VOA is high and VOB is low when the PWM input is high, and VOA is low and

VOB is high when the PWM input is low.

2.6.4 Enable Input

When brought low, the EN input unconditionally drives VOA and VOB low regardless of the states of VIA and VIB. Device operation

terminates within tSD after EN = VIL and resumes within tRESTART after EN = VIH. The EN input has no effect if VDDI is below its

UVLO level (i.e., VOA, VOB remain low). The EN pin should be connected to GNDI through a 100 kΩ pull-down resistor.

2.6.5 Delayed Startup Time

Product options Si82390/4/5/7 have a safe startup time (tSTARTUP_SAFE) of 1ms typical from input power valid to output showing

valid data. This feature allows users to proceed through a safe initialization sequence with a monotonic output behavior.

2.6.6 RDY Pin

This is a digital output pin available on all options except the Si82397. The RDY pin is “H” if all the UVLO circuits monitoring VDDI,

VDDA, and VDDB are above UVLO threshold. It indicates that device is ready for operation. An “L” status indicates that one of the

power supplies (VDDI, VDDA, or VDDB) is in an unpowered state.

2.7 Programmable Dead Time and Overlap Protection

All high-side/low-side drivers (Si82394/8) include programmable dead time, which adds a user-programmable delay between transitions

of VOA and VOB. When enabled, dead time is present on all transitions. The amount of dead time delay (DT) is programmed by a

single resistor (RDT) connected from the DT input to ground per the equation below. Note that the dead time pin should be connected

to GND1 through a resistor between the values of 6 kΩ and 100 kΩ and a filter capacitor of 100 pF in parallel as shown in Figure

3.1 Si82394/8 Application Diagram on page 18. It is highly recommended it not be tied to VDDI. See Figure 2.18 Dead Time Wave-

forms for High-Side/Low-Side Drivers on page 17 below.

Figure 2.18. Dead Time Waveforms for High-Side/Low-Side Drivers

2.8 De-glitch Feature

A de-glitch feature is provided on some options, as defined in the Ordering Guide. The de-glitch basically provides an internal time de-

lay during which any noise is ignored and will not pass through the IC. It is about 30 ns; so, for these product options, the prop delay will

be extended by 30 ns.

3. Applications

The following examples illustrate typical circuit configurations using the Si8239x.

3.1 High-Side/Low-Side Driver

The following figure shows the Si82394/8 controlled by a single PWM signal.

Figure 3.1. Si82394/8 Application Diagram

In the above figure, D1 and CB form a conventional bootstrap circuit that allows VOA to operate as a high-side driver for Q1, which has

a maximum drain voltage of 1500 V. VOB is connected as a conventional low-side driver. Note that the input side of the Si8239x re-

quires VDDI in the range of 2.5 to 5.5 V, while the VDDA and VDDB output side supplies must be between 6.5 and 24 V with respect to

their respective grounds. The boot-strap start up time will depend on the CB cap chosen. Also note that the bypass capacitors on the

Si8239x should be located as close to the chip as possible.

3.2 Dual Driver

The following figure shows the Si82390/1/5/6/7 configured as a dual driver. Note that the drain voltages of Q1 and Q2 can be refer-

enced to a common ground or to different grounds with as much as 1500 Vdc between them.

Figure 3.3. Si82390/1/3 with Enhanced UVLO Feature Application Diagram

Because each output driver resides on its own die, the relative voltage polarities of VOA and VOB can reverse without damaging the

driver. A dual driver can operate as a dual low-side or dual high-side driver and is unaffected by static or dynamic voltage polarity

changes. The Si82390/1/3 come equipped with an enhanced UVLO feature as described in 2.6.2 Undervoltage Lockout. This feature is

intended for systems which provide VDDA and VDDB as independent isolated power supplies. Si82390/1/3 are not recommended for

use with bootstrap configuration for driver supply since the driver output will not be asserted unless both VDDA and VDDB are above

the UVLO threshold.
