Product details

8A charger for single-cell fast-charge designs

The Texas Instruments BQ25971YFFR is a single-cell multi-chemistry battery charger that delivers up to 8A charge current with a 4.65V battery pack voltage ceiling, controlled via an I²C interface. It integrates over-current and over-voltage fault protection, reducing the external protection component count on the board. The 56-DSBGA (3.33x2.93 mm) package fits the tight floorplan of a smartphone or power bank PCB.

I²C programmability and protection

The I²C interface lets the system host adjust charge current, termination threshold, and battery regulation voltage on the fly — useful for adaptive fast-charging profiles that trade off charge time against thermal budget. The built-in over-current and over-voltage protection catches a fault before it reaches the battery, which saves adding a separate protector IC.
