Product details

Charge current is programmable up to 2A, and the device monitors battery pack voltage to a 4.44V max ceiling. Fault protection covers over-temperature and over-voltage events — the chip handles the safety checks so the system MCU does not have to.

DSBGA footprint — plan the rework flow

The BQ24187YFFT comes in a 36-DSBGA package measuring 2.63x2.46 mm — that is a tiny ball-grid array. Surface-mount only. No lab, no bench, let us go: if you are field-swapping this, you need a hot-air station and a steady hand.
