LI+ DUAL BATTERY CONTROLLER
GENERAL DESCRIPTION
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.
Additionally, IS31PW8200 integrates an I2C block to
communicate with the Base Band. At start up, the
baseband reads out the status of the dual battery
sources. During operation, if the status changes,
IS31PW8200 provides an interrupt to notify the
baseband to update the information of the dual
battery sources.
IS31PW8200 is available in QFN-20 (3mm × 3mm)
package. It operates from 2.4V to 5.5V over the
temperature range of -40°C to +85°C.

Figure 2 Typical Application Circuit
Note 1: Two ADC circuits can be used to detect the battery voltage. Connecting to the VC point if only one ADC. This circuit can be connected
or not.
In MTK Platform, R1=R3=470k, R2=R4=300k. In Zhanxun Platform, R1=R3=470k, R2=R4=100k.
Note 2: The adapter provides power for system when the adapter plugs in and no batteries connected. Please refer to Page 12 to get the detail
information. This circuit can be connected or not.
Note 3: Base Band can control and read the dual batteries information. Please refer to Page 9 to get the detail information. This circuit can be
connected or not. Register configuration is default if there is no connection.
Note 4: If use the two-pin battery, BATA_ID and BATB_ID pins should connect a 10kresistor to ground. Three-pin battery is recommended.
