NTC ( JP12 )
Input to the Thermistor Monitoring Circuits. The NTC pin connects to a battery’s thermistor to determine if the
battery is too hot or too cold to charge. If the battery’s temperature is out of range, charging is paused until it re-
enters the valid range. A low drift bias resistor is required from VIN to NTC and a thermistor is required from NTC
to ground. If the NTC function is not desired, the NTC pin should be grounded This jumper is installed by default.
