BQ27425YZFT-G2A Description

Short technical summary and product information.

The BQ27425YZFT-G2A from Texas Instruments is an easy-to-configure fuel gauge IC for single-cell Lithium Ion and Li-Polymer batteries. It resides on the system board and supports embedded or removable batteries, powered directly from the battery with an integrated LDO.

 

This fuel gauge employs the patented Impedance Track algorithm to provide accurate remaining capacity and state-of-charge (SOC) information. It automatically adjusts for battery aging, self-discharge, temperature, and rate changes, and can estimate battery state-of-health. The device communicates via a 400-kHz I2C serial interface and includes an internal temperature sensor.

 

Key specifications include a battery capacity range of 100 mAh to 4000 mAh, a single-cell configuration, and an operating temperature range of -40°C to 85°C. It features a low-value integrated sense resistor (10 mΩ typical) and is housed in a compact 15-DSBGA package suitable for surface mounting.

 

This IC is ideal for applications requiring precise battery monitoring without extensive firmware development. Its system-side implementation simplifies design and allows for direct battery power. The configurable SOC interrupt or battery low digital output provides additional system control.
