What this protection IC does for a Li-ion pack
The BQ24313DSGT is a single-chip Li-ion battery protection IC that monitors the cell for overcurrent, overtemperature, and over/under voltage conditions. It disconnects the load or charger when any fault threshold is crossed, preventing cell damage or thermal runaway.
Package and thermal pad design
The supplier device package is 8-WSON (2x2) — a 2 mm × 2 mm footprint that fits tight battery-pack layouts.
