pin FuncTions
NTCBIAS (Pin 1): NTC Bias Pin. Connect a resistor from
NTCBIAS to NTC, and a thermistor from NTC to GND. Float
NTCBIAS when not in use. Minimize parasitic capacitance
on this pin.
NTC (Pin 2): Input to the Negative Temperature Coefficient
Thermistor Monitoring Circuit. The NTC pin connects to
a negative temperature coefficient thermistor which is
typically co-packaged with the battery to determine the
temperatureofthebattery.Ifthebatterytemperatureistoo
high, the float voltage is reduced. Connect a low drift bias
resistor from NTCBIAS to NTC and a thermistor from NTC
to GND. When not in use, connect NTC to VCC. Minimize
parasitic capacitance on this pin.
ADJ (Pin 3): Float Voltage Adjust Pin. Connect ADJ to GND
to program 4.0V float voltage. Disconnect ADJ to program
4.1V float voltage. Connect ADJ to VCC to program 4.2V
float voltage. The float voltage is also adjusted by the NTC
thermistor.
