FUNCTIONAL PIN DESCRIPTION
Name
Description
BAT
Charging Output - This pin is wired to the positive terminal of the battery. (The negative battery terminal is wired to GND.)
CCP
Charge Current Programming Pin - A resistor (RCP) is connected between this pin and GND. The constant current is
determined by the following relationship:

PSW
PMOS Switch driver – This output is designed to drive the gate of an external PMOS power switch. The driver is pulled low
(PMOS on state) when VDD > VBAT.
VDD
Common Power Node – Connects to system power bus.
VIDx
State Select Input – Applying a two bit TTL compatible signal sets the desired state of the charger corresponding to the Truth
Table.
USB
Voltage Input – Current limited USB input. Apply a USB compliant power input.
VM
Voltage Mode Select - Selects the constant voltage charge level. Wired to USB for 4.1V and GND for 4.2V.
STAT
Status - This pin is a logic high level when the battery is being charged. A low signal indicates either under voltage lockout,
charge completed, or VBAT > VDD, or VID0 = VID1 = 0.
