BQ27541DRZT-G1 Description

Short technical summary and product information.

The Texas Instruments BQ27541DRZT-G1 is a microcontroller peripheral designed for single-cell Li-Ion battery fuel gauging applications, supporting capacities up to 32Ahr. It utilizes the patented Impedance Track™ algorithm to provide accurate battery information such as remaining capacity, state-of-charge, run-time to empty, battery voltage, and temperature.

 

This device offers advanced fuel gauging features including internal short detection and tab disconnection detection. It supports SHA-1/HMAC authentication for secure battery pack authentication and includes lifetime data logging. The BQ27541DRZT-G1 is housed in a compact 12-SON (2.5x4) package and is suitable for surface mounting.

 

Key electrical specifications include an I2C interface and a sense resistor range of 5mΩ to 20mΩ. The operating temperature range is -40°C to 85°C (TA). The device also provides an internal or external temperature sensor for battery temperature reporting and features 64 Bytes of Non-Volatile Scratch Pad FLASH memory.
