Pin Function
Supply pin, connect to adaptor power.
Adapter input voltage. This pin provides a bias voltage approximately equal to the adapter
input voltage. The output current when charging will be reduced by the load current on VCCIL.
Charger output, connect to battery.
Current limit program pin for charge and LDO-mode. Requires a resistor to ground to program
fast-charge current.
Selection for current termination and pre-charge current. Requires a resistor to ground to
program pre-charge and termination current.
Ground
Combined device enable/disable and NTC input pin. Logic low disables the device. Analog
voltages between 0.3VCC and 0.75VCC enable the NTC function. Voltages above 95% of
VCC force the NOBAT output high.
Battery Present Indicator. This output goes high when the NTC voltage exceeds 95% of VCC
indicating the Battery and NTC have been removed.
Charge time programming resistor. Connect a resistor between RTIME and GND to program
the charge time. Force the pin to GND to disable the timer. Force the pin to VCC to select
LDO-mode.
Output status indicator designed to drive two LEDs. Connect cathode of the 'charging' led to
this pin to indicate charge in progress. Connect the anode of the 'charge complete' led to this
pin to indicate charge complete.
