The BQ27441DRZR-G1A from Texas Instruments is a microcontroller peripheral designed for system-side fuel gauging of single-cell Li-Ion batteries. This device operates within a temperature range of -40°C to 85°C and communicates via an I2C interface.
Key features include the patented Impedance Track™ algorithm, which provides accurate reporting of remaining capacity and state-of-charge. The algorithm automatically adjusts for battery aging, self-discharge, temperature, and rate changes, offering reliable battery state-of-health estimations. It supports battery capacities ranging from 200 mAh to 8000 mAh.
This fuel gauge is suitable for system implementations requiring embedded or removable batteries. It is powered directly from the battery and includes an integrated LDO. The device supports a low-value external sense resistor (10 mΩ) and is available in a 12-VFDFN exposed pad package, also referred to as 12-SON (2.5x4).
The BQ27441DRZR-G1A is designed to reside on the system board, providing essential battery monitoring functions for various electronic devices.
