Description
Low Battery A Voltage Input. Connect to the resistive divider to set the trip level for chip-on
moment. If LOBAT is less than 0.8V, VOUT is connected to BATB.
Charging Input. Charging path input.
Supply Input. Battery A voltage input.
Battery Selector Status. Open-drain output. HIGH (Hi-Z) means battery A connects to
VOUT. LOW means battery B connects to VOUT.
Battery B Indicator. Connect this pin with the ID pin at the battery pack of BATB. HIGH
means battery B absent; LOW means battery B present.
Switch Output. Connect to system load.
Adapter Input. 5V input for battery charger.
Battery A Indicator. Connect this pin with the ID pin at the battery pack of BATA. HIGH
means battery A absent; LOW means battery A present.
Supply Input. Battery B voltage input.
Ground
Reset Input. Active LOW. Both system path switches are disconnected from system load.
Battery Selection Input. HIGH means to switch battery B to VOUT; LOW means to switch
battery A to VOUT.
Charge Selection Input. HIGH means to charge battery B: LOW means to charge battery A.
