The BQ27531YZFT-G1 from Texas Instruments is an integrated circuit designed for battery management, specifically functioning as a fuel gauge for 1-cell Lithium Ion battery applications. It resides on the system main board and utilizes patented Impedance Track™ technology to model battery discharge curves for accurate time-to-empty predictions.
This device automatically adjusts for battery aging, self-discharge, and temperature/rate inefficiencies. It supports a low-value sense resistor (5 mΩ to 20 mΩ) and includes a battery charger controller with customizable charge profiles. The configurable charge voltage and current can be based on temperature, with optional State of Health (SoH) and multilevel-based charge profiles.
The BQ27531YZFT-G1 operates within a temperature range of -40°C to 85°C and features a 400-kHz I²C interface for communication with a system microcontroller. It is supplied in a 15-pin DSBGA package, suitable for surface mounting.
Key features include its host-free autonomous battery management system, which reduces software overhead and allows for easier portability across platforms. It also offers enhanced safety and security through intelligent, customized, and adaptive charging profiles, including temperature level charging (TLC).
