... V • too close to V FAULT Output Pin (LTC1730EGN-4) The FAULT pin is pulled to ground when either one of the following conditions is detected: 1. The voltage at the NTC/SHDN pin is out of the operation range. With a 10k negative temperature coefficient thermistor placed near the battery pack, this pin indi- cates that the temperature of the pack is either too cold or too hot and the charger is suspended ...
