3 A charge current with I²C programmability
The I²C interface lets the host controller adjust the charge current, termination threshold, safety timer, and battery regulation voltage on the fly — useful when the same PCB must support different cell capacities or chemistries.
Protection and temperature range
On-chip fault protection covers over-current, over-voltage, and over-temperature conditions — the part shuts down before the external MOSFET or inductor sees stress.
