IS31PW8200 Multi-Function I/O Driver Evaluation Board Guide DESCRIPTION RECOMMENDED EQUIPMENT The IS31PW8200 is a highly integrated IC to serve as the control logic for a system with multiple power sources. It integrates a mini-charger’s path power MOS with a switchable bulk and saves the external diode in mini-charger path. Also, it directly drives the internal P-channel MOSFETs to select the power path for the system and manages dual battery sources for charge and discharge. The power path selection is made based on the present voltage of the power sources and the state of charge of the batteries. FEATURES PROCEDURE The IS31PW8200 evaluation board is fully assembled and tested. Follow the steps listed below to verify board operation. 2.4V to 5.5V supply voltage I2C interface Complete power path management for dual battery systems Dual battery status monitor Integrated charger path switches Hardware reset function QFN-20 (3mm × 3mm) package ABSOLUTE MAXIMUM RATINGS ≤ 5.5V power supply Caution: Do not exceed the conditions listed above, otherwise the board will be damaged. Caution: Do not turn on the power supply until all connections are completed. 1) 2) QUICK START 3) 4) 5) 6) Figure 1: Photo of IS31PW8200 Evaluation Board 3V~5.5V, 2A power supply 2 Batteries 5V Charger 7) 8) Please charge the batteries A and B both full before test. Connect the anode of Battery A to BATA terminal and the anode of Battery B to BATB terminal. Connect the power supply ground, PCB ground to GND terminal and connect VBAT terminal to the anode of power supply. Connect the BAT_ID between IS31PW8200 and corresponding Battery A/B. Ensure the BAT_ID of batteries is low level. (There is a 10kΩ resistor connect BAT_ID to GND) INTB is an interrupt signal output port which shows the state of batteries. The MCU should provide interrupt port and connect a 10kΩ resistor to VDD. The SCL line is uni-directional. The SDA line is bi-directional (open-collector) with a pull-up resistor (typically 4.7kΩ). When Close=Reset, the IC enters into hardware reset mode. In this mode batteries will disconnect to VBAT. AD0 and AD1 are the slave address. When AD1/AD0 connects to VDD, AD1/AD0=1; when AD1/AD0 connect to GND, AD1/AD0=0. It can be configured by the jumper JP1 and JP2. Connect the corresponding anode of adapter to AC terminal and cathode to GND if charging batteries by the internal charger of IS31PW8200.
