Texas Instruments BQ24190 Universal Power Path & 4.5A Charging IC Chip

The Texas Instruments BQ24190 Charger IC is a professional-grade, highly integrated switch-mode battery charge management and system power path distribution semiconductor designed for component-level smartphone and tablet motherboard repairs. Housed in a dense 24-pin VQFN package with an exposed center thermal pad, this advanced chip controls automated multi-stage charging phases (pre-conditioning, constant current, and constant voltage) alongside Narrow VDC (NVDC) power path management. It dynamically regulates current routing to power downstream systems even when the device’s battery is deeply depleted or completely disconnected.
