An external capacitor connects between this pin and ground (Pin 6) to set the sample timer frequency and
á
á
path for charge switch Q1. A current limit fault is set when the combined voltage drop of charge switch Q1 and
load; or charge current limit threshold voltage, Vth(chg) below Pin 6 caused by a charger.

charging.
á
á
This is the ground pin of the IC.
á
á
This input connects to the positive terminal of the cell for voltage monitoring and provides operating bias for the
integrated circuit. Internally, the Cell Voltage Sample Switch periodically applies this voltage to a resistor divider
where it is compared by the Cell Voltage Detector to an internal reference.
