Charge current is constant and programmable up to 2A max, and the battery regulation voltage is fixed at 4.2V. The input supply can go up to 10.5V, which covers standard 5V USB and 9V adapters with margin.
Fault protection and operating range
On-chip fault protection covers over-current, over-temperature, and over-voltage conditions — the charger will shut down or fold back without external supervisory circuitry.
30-DSBGA package — layout and assembly considerations
The part comes in a 30-DSBGA package. The small footprint saves board space but requires careful thermal management.
The base product number is BQ24250, and the YFFR suffix identifies the 30-DSBGA package and the Tape & Reel / Cut Tape shipping options. There is no official second source or pin-compatible alternate listed; the I²C programming model is specific to this TI family.
