... In the F type, the release voltage (+V overcharge detection of lithium-ion battery packs. In the E type, the input voltage monitoring pin of the voltage detector is externally connected as the SENSE pin. Because this pin is configured by a resistor only, temporary current such as a through-type current does not flow. Consequently even when resistor (R VIN pin, the input power voltage can be accurately monitored by connecting the SENSE pin to the input power supply ...
