The BQ24725ARGRR from Texas Instruments is an SMBus controlled, NMOS-NMOS synchronous buck battery charge controller designed for 1 to 4 cell Li-Ion or Li-Polymer battery packs. It offers programmable input current, charge voltage, and charge current limits, with high accuracy for charge voltage (±0.5%) and charge current (±3%).
Key features include input over-voltage protection (OVP), power path control, and enhanced safety features such as over-current protection and short-circuit protection for the battery, inductor, and MOSFETs. The device operates within a temperature range of -40°C to 85°C and is available in a 20-VQFN package measuring 3.5mm x 3.5mm.
This charge controller supports programmable switching frequencies of 615kHz, 750kHz, and 885kHz. It automatically selects the system power source from the adapter or battery. The device also includes integrated soft start and loop compensation, along with real-time system control on the ILIM pin to limit charge current.
