BQ24725RGRT Description

Short technical summary and product information.

The BQ24725RGRT from Texas Instruments is an SMBus host-controlled synchronous buck battery charge controller designed for 2 to 4 cell Lithium-Ion or Li-Polymer batteries. It offers a maximum charge current of 8A and supports input voltages up to 24V, with an absolute maximum rating of 30V. The device features programmable input current, charge voltage, and charge current limits, with high accuracy for charge voltage (±0.5%) and charge current (±3%).

 

Key electrical characteristics include a wide battery charge voltage range from 1.024V to 19.2V and programmable switching frequencies of 615kHz, 750kHz, and 885kHz. The interface is SMBus, enabling real-time system control. Enhanced safety features include over-voltage protection, over-current protection, and short-circuit protection for the battery, inductor, and MOSFETs.

 

Packaged in a 20-VQFN (3.5x3.5mm) with an exposed pad, the BQ24725RGRT is designed for surface mounting. Its operating temperature range is 0°C to 125°C (TJ). This IC is suitable for applications such as portable notebook computers, UMPCs, ultra-thin notebooks, netbooks, personal digital assistants, handheld terminals, and other industrial and medical portable equipment requiring efficient battery management.
