BQ27541DRZT-G1概述

单节锂离子电池电量计的电池组集成 Single Cell Li-Ion Battery Fuel Gauge for Battery Pack Integration

The Texas Instruments bq27541-G1 Li-ion battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell Li-ion battery packs. The device requires little system microcontroller firmware development for accurate battery fuel gauging. The fuel gauge resides within the battery pack or on the main board of the system with an embedded battery nonremovable.

The fuel gauge uses the patented Impedance Track™ algorithm for fuel gauging, and provides information such as remaining battery capacity mAh, state-of-charge %, run-time to empty minimum, battery voltage mV, and temperature °C. It also provides detections for internal short or tab disconnection events.

The fuel gauge also features integrated support for secure battery pack authentication, using the SHA-1/HMAC authentication algorithm.
