Texas Instruments BQ25601D I2C Controlled 3A Charging IC Chip

The Texas Instruments BQ25601D Charger IC is a professional-grade, highly integrated switch-mode battery charge management and Narrow VDC (NVDC) power path management semiconductor designed for expert motherboard-level mobile repairs. Utilizing a 1.5-MHz synchronous buck topology, this advanced integrated circuit (IC) achieves up to 92% charging efficiency at a 2A output, effectively reducing thermal dissipation across multi-layered printed circuit boards (PCBs). It features an intelligent input system supporting a 3.9V to 13.5V operating range with a 22V absolute maximum over-voltage protection limit to safeguard downstream components from destructive electrical spikes.
