Description

The Texas Instruments bq27621-G1 is an easy to configure microcontroller peripheral that provides system-side fuel gauging for single-cell Li-ion batteries. This device requires minimal user configuration and system microntroller development. The design will provide State of Charge indication for Li-Ion batteries.

Features
  • Eliminates the need for a sense resistor;
  • Powered directly from battery with integrated LDO;
  • Supports both embedded and removable batteries; Easy to configure based on the Dynamic Voltage Correlation algorithm
