The BQ27441DRZT-G1A from Texas Instruments is a microcontroller peripheral that provides system-side fuel gauging for single-cell Li-Ion batteries. This device employs the patented Impedance Track™ algorithm to report remaining capacity and state-of-charge (SOC) with a smoothing filter.
Key features include automatic adjustment for battery aging, self-discharge, temperature, and rate changes, along with battery state-of-health (aging) estimation. It communicates via a 400-kHz I2C serial interface and supports a low-value external sense resistor (10 mΩ).
Designed for system board implementation, it supports both embedded and removable batteries and is powered directly from the battery with an integrated LDO. The operating temperature range is -40°C to 85°C. The package is a 12-SON (2.5x4 mm) or 12-VFDFN Exposed Pad, suitable for surface mounting.
This fuel gauge is ideal for applications requiring accurate battery monitoring and management in portable electronics, IoT devices, and other battery-powered systems.
