The BQ27421YZFR-G1B from Texas Instruments is a system-side fuel gauge IC designed for single-cell Lithium Ion and Li-Polymer batteries. This minimally configured microcontroller peripheral provides accurate remaining capacity and state-of-charge (SOC) reporting.
Key features include the patented Impedance Track algorithm, which automatically adjusts for battery aging, self-discharge, temperature, and rate changes, ensuring reliable fuel gauging. It also incorporates an integrated sense resistor, simplifying implementation and reducing component count. The device communicates via a 400-kHz I2C serial interface.
Designed for system-side implementation, the BQ27421YZFR-G1B resides on the system board and can support embedded or removable batteries. It operates within a temperature range of -40°C to 85°C and supports battery capacities from 100 mAh to 8000 mAh.
This fuel gauge IC is suitable for applications requiring precise battery monitoring, such as portable electronics, medical devices, and IoT products where battery life management is critical.
