Pin 1 2 3 Symbol ISNS ISEL COMP/DIS Description This is one of the inputs to the current regulator and the end-of-charge comparator. A resistor from this pin to ground pin sets the full charging current regulation level. This is a multifunctional pin that is used for compensation and can be used to interrupt charge with an open drain/collector output from a.
