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 municate with the Base Band. At start up, the baseband reads out the...
