TIBQ27530YZFT-G1
Overview
The BQ27530YZFT-G1 is a single-cell Li-Ion battery fuel gauge and charger controller utilizing TI's proprietary Impedance Track technology. It provides highly accurate state-of-charge (SOC) monitoring by compensating for battery aging, self-discharge, and temperature variations while managing the charge cycle autonomously via I2C.
Why Choose This Part
This IC minimizes software overhead by operating as a host-free autonomous battery management system that can directly control the charger. It supports low-value sense resistors (5 mOhm to 20 mOhm) to reduce power dissipation and features MaxLife technology to extend battery cycle life through tighter charge termination controls.
Applications
Key Specifications
Getting Started
To evaluate the BQ27530, engineers typically use the BQ27530EVM evaluation module alongside the EV2400 interface tool for PC-based configuration. Implementation requires calibration of the Impedance Track algorithm by performing a learning cycle with the specific battery chemistry used in the design.
