For convenience, a precision 5 V reference IC and four trim pots are built in to the evaluation board, for driving the battery current and voltage ISET and VSET inputs. All device pins are accessible with test loops or probe landings. At the same time, the AD8452-EVALZ has the flexibility to interface and drive a typical half bridge inductor input SMPS with output levels in the 1 A to 15 A range. SMPS and associated components are specified and sourced by the user. ADDITIONAL EQUIPMENT NEEDED +12 V, +5 V, -5 V bench supply: Keysight E3631 or equivalent power supply with current metering and adjustable output current-limiting 50 mV diode emulation/current-limiting bias voltage Oscilloscope: Tektronix DPO7104 or multichannel equivalent DMM: 41/2 digit or greater Test jumpers with grabber or mini-gator clips Optional: power amplifier, Li-Ion battery, current transducer (low resistance shunt) The AD8452 is intended for use as the core controller for commercial battery test and formation systems.

Refer to the AD8452 data sheet for a full description. The AD8452 is a front-end controller for battery test or formation systems. It is a 48-lead device in a 7 mm x 7 mm LQFP package, comprised of a high performance analog section and PWM. UG-1180 AD8452-EVALZ User Guide EVALUATION BOARD HARDWARE A description of some simple experiments with the AD8452 follows. The AD8452-EVALZ can be connected as the analog and PWM small signal digital controller of a complete battery formation system, allowing users to explore the AD8452 functions in detail, with an emulated system input/output (I/O) provided. The board can also be operated as a channel controller for a power channel custom designed to the unique needs and requirements of the user. Figure 3 is a system level block diagram comprising three functional system level block diagrams, an AD8452-EVALZ block diagram, including its user adjustable current and voltage control compensation matrix, and a simple precision reference (an ADR4550) for driving current and voltage inputs throughout the PWM conversion process to the outputs DH and DL. The balance of the large signal system in Figure 3 is user supplied and consists of the metal-oxide semiconductor field effect transistor (MOSFET) driver and user supplied SMPS, an inductorcapacitor (L-C) output filter with a current limiting resistor (RCL), and a current sense shunt.

Typical Setup for the AD8452-EVALZ Bench Test Jumper Positions DC Testing--Board Setup and Power Supply Currents There are five 2-pin jumpers installed on the evaluation board (see Figure 5). Table 1 shows their location and function. With the evaluation board set up as shown in Figure 4, the power supply currents are those shown in Table 2. The test loops in Figure 4 are color coded: black is for ground; red for positive voltages; orange for negative voltages; green for 5 V logic supplies; and purple corresponds to the signal test points shown in the schematic (see Figure 8). When power is applied to the evaluation board, there can be a momentary current surge, especially if the filter capacitors are not recently charged. This behavior is normal, and the supply currents settle to their typical values in a few seconds. It is strongly recommended that the power supply used for experimenting feature current metering and current-limiting. Table 1.

Jumper CONN_VIN can be removed if the user needs to test the device with higher supply voltages. Otherwise, it is recommended to remain in place. 5 V Reference Supply and Input Trimmers The AD8452-EVALZ includes the ADR4550 on-board 5 V reference (U2) for a stable input source. The difference amplifier measures battery voltage. The polarity of the voltage is always positive; however, the difference amplifier gain is <1 to reduce the integrator voltage to a value within the linear range of the integrator. To exercise the difference amplifier, set the mode switch to the charge position (switch handle to the right), apply 1 V dc from a voltage source from VBATH to VBATL, and connect VBATL to a nearby ground pin with a grabber clip jumper). Verify that the output at BVMEA is 0.4 V 0.4 mV. Pin FREQ and Pin SYNC Four trimmers provide independent control voltages for current and voltage in both charge/discharge modes. This makes switching from charge to discharge possible without having to reset the current or voltage control levels. These levels are factory set and are not likely to require adjustment. Charge current, discharge current, and charge voltage are set at 2.5 V. Discharge voltage is set for 1.5 V so that tests of the PWM function can occur with the expected polarity of battery voltage and current flow. Current Limit Threshold Voltage (at Pin CLVT) The CLVT pin voltage is generated by forcing 20 A through Resistor R104 (4.99 k). When probing Pin CLVT to measure the voltage, look for a small bare copper dot above and to the left of U1, Pin 37. The voltage is 105 mV + 30 mV or - 25 mV To disable the current limit function, pull Pin CLVT high. Instrumentation Amplifier (In-Amp) When installed as intended in a system, the in-amp measures bidirectional battery current, and is controlled by the MODE function. If the mode switch is in charge (that is, the handle is to the right), Pin ISMEA measures 0.660 V with a 10 mV voltage from VSHH to VSHL. When the mode switch is in discharge mode, the voltage at ISMEA still reads 0.660 V, because the mode switch reverses the input voltage polarity. However, the voltage at ISMEA reads -0.660 V if the 10 mV input voltage polarity is reversed and the mode switch remains in charge mode. This type of test is useful to verify that the inamp output swings both positive and negative outputs. The inputs to the in-amp are floating. If the output voltage floats high, connect VSHL to a nearby ground pin with a grabber clip jumper or a small soldered wire. Difference Amplifier Apply power and activate the enable switch (move the switch handle to the lower position). Connect a digital multimeter (DMM) probe to Pin FREQ and verify that the dc voltage reads 1.25 V. Under the same conditions, connect a scope probe to Pin SYNC. Observe a square wave with a period of 10 s 1 s. Soft Start--DC at Pin SS and Turn On Ramp Activate the enable switch. After 1 second, verify that the dc voltage on Pin SS reads 4.9 V to 5 V. The only way to change the turn on delay of the AD8452 is to change Capacitor CSS. Use a good quality ceramic capacitor such as an NP0/C0G or a high dielectric X7 style, because the capacitor ramp time is a function of the 20 A current source. Less stringent performance capacitors such as the Y5 series are sufficient for many applications, but can exhibit enough leakage to fail before the maximum applied voltage is realized. An easy calculation for capacitor value is to scale the capacitor by the desired ramp time. The default ramp time for the capacitor installed in the evaluation board is 1 sec, achieved with a 1 F capacitor. To reduce the time by a factor of 10, exchange the 1 F capacitor for a 0.1 F model. Test of PWM and Driver Outputs DH and DL for Charge and Discharge Modes The following two experiments demonstrate the timing and waveform details of the AD8452 in real time, using a scope, with file storage capabilities for future reference. Figure 5 shows a photograph of the setup for the experiment, and Figure 6 and Figure 7 show a 100 kHz clock and PWM outputs of the high and low gate drivers (DH and DL, respectively), along with the controlling analog signal (VINT). Two slightly different setups demonstrate the operation of the AD8452 in charge and discharge modes. Rev. 0 | Page 6 of 14 UG-1180 16188-005 AD8452-EVALZ User Guide Figure 5. Typical Test Setup for Scope Observations Charge Mode Connect the vertical inputs of a 4-channel oscilloscope to the four outputs of the AD8452-EVALZ (listed in Table 3). The Pin DH and Pin DL waveforms are the control signals for the output power MOSFET switches. Table 3. Scope Connections to Observe Driver Waveforms Channel 1 2 3 4 Function Displays the clock signal High switch drive (DH) Low switch drive (DL) Integrator output (VINT) Pin SYNC (clock waveform) Test Loop DH P2-2 (center pin) VINT On the scope, set the vertical scale of all four channels to 5 V per division (5 V/div) and select Channel 1 as the trigger source. Before applying power to evaluation board, verify that the ENABLE switch is in the up position. Connect the amplifier inputs and jumpers according to the following steps: 1. 2. 3. 4. 5. Connect a jumper from the VINT test loop to the VVE1 test loop. This connection sets the gain of the constant voltage (CV) loop to unity. Verify that there are shorting shunts installed from P1-1 to P1-2 and from P1-3 to P1-4. These jumpers set the output voltages VISMEA and BVMEA to 0 V by ensuring that the current shunt and battery voltage inputs are 0 V. Connect the positive lead from a 50 mV bias supply to Pin CLP (the current limit positive pin) to Pin CLN (the current limit negative pin). Move the MODE switch to charge (switch handle to the right). Enable the AD8452 by moving the ENABLE switch handle to the down position. The output voltages appear as shown in Figure 6. Note that SYNC (Channel 1, the black pulse display) and DH (Channel 2, blue pulse display) are in phase with one another, while SYNC and DL (Channel 3, red) are 180 out of phase with one another. The antiphase relationship of DH and DL are important, because it ensures the two output devices are never switched on at the same time, and it forces current from the supply to the load (battery). Discharge Mode With the circuit disabled (the ENABLE switch is in the up position), follow the same steps as in the Charge Mode section, with the following exceptions: 1. Move the VINT jumper from the VVE1 test loop to the VVE0 test loop. This connection sets the CV loop gain to unity again, but in discharge mode. 2. Remove the shorting shunt from P1-3 to P1-4 and, using two jumpers, connect the VBATH test loop to 5 V, and connect the VBATL test loop to ground. 3. Reverse the polarity of the 50 mV bias supply by connecting the positive lead from the 50 mV bias supply to Pin CLN and the negative lead to Pin CLP. 4. Move the MODE switch to discharge (switch handle to the left). Enable the AD8452 by moving the ENABLE switch handle to the down position. The output voltages appear as shown in Figure 7. Note that DL is in phase with SYNC, and DH is 180 out of phase with SYNC. This phase relationship forces current from the load (battery) back to the supply. Rev. 0 | Page 7 of 14 UG-1180 AD8452-EVALZ User Guide Another useful experiment can be performed using the same setup described previously, by changing scope settings. Instead of a 10 s/div free running horizontal sweep, set the horizontal control to single sweep and the scale to a longer interval, such as 200 ms/div. Disable the AD8452, clear the scope screen of any prior waveforms and reenable the AD8452. Expect to see a timing sequence in which DH comes on before DL in charge mode, and the opposite in discharge mode. See the Soft Start section in the AD8452 data sheet for more details.
