VPRGM
IPRGM
Selectable voltage program pin. Logic low = 4.1V. Logic high = 4.2V. Resistor = adjustable.
Charger current program pin in fast charge mode. Requires a resistor to ground to program
fast-charge current.
4
ITERM
Selection for current termination and pre-charge current. Requires a resistor to ground to
program pre-charge and termination current.

Device enable/disable pin. Logic high enables device. Logic low disables device.
BIP
Input derived from external circuitry or microcontroller that signals Battery In Place. Logic high
indicates Battery In Place and in charging mode. Logic low puts device into LDO mode. Do
not leave this pin floating.
9
OVP
Overvoltage fault flag if charger input voltage is higher than 6.5V This pin can Source 10mA.
10
STAT
Charger Status Pin: Pre-charge (High), Fastcharge (High) and end of charge (Low). When in
LDO mode this pin is high impedance. This pin can source 10mA.
11
CP
Charger present indicator, logic high when there is power to the VCC pins regardless of the
Enable pin state. This pin can source 10mA.
