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 microcontroller. When this pin is pulled to ground, the charge current is interrupted.
This is the ground pin of the IC.
This is an input that is used to sense battery voltage and is the other input to the current regulator. It also serves
as the input to the battery overvoltage comparator.
An open drain output that indicates the battery charging status.
This is a multifunctional pin that powers the device and senses for over and undervoltage conditions.
This is a current source driver for the pass transistor.
