The BQ24725A from Texas Instruments is an advanced battery charge controller IC utilizing a switch-mode buck topology. It is designed for managing the charging of 1 to 4 series Li-Ion or Li-Polymer cells.
Key electrical specifications include a maximum charge current of 8A, an input voltage range from 4.5V to 24V (absolute maximum 30V), and a programmable charge voltage range of 1.024V to 19.2V. The device offers high accuracy for charge voltage (±0.5%), charge current (±3%), and input current (±2%). It operates with a programmable switching frequency of 615kHz, 750kHz, or 885kHz.
This SMBus controlled IC features N-channel MOSFET selection for system power source from adapter or battery. Enhanced safety features include over-voltage protection, over-current protection, and short circuit protection for battery, inductor, and MOSFETs. The operating temperature range is -40°C to 85°C.
The BQ24725A is housed in a 20-pin VQFN package measuring 3.5mm x 3.5mm. It supports automatic adapter detection and includes integrated soft start and loop compensation.
