Product Introduction

Overview

The BQ27210DRKRG4 is a highly accurate, stand-alone single-cell Li-Ion and Li-Pol battery capacity monitoring and reporting IC, part of the bqJUNIOR series by Texas Instruments. This component is designed for space-limited, portable applications and provides comprehensive battery monitoring capabilities. It operates directly from single-cell Li-Ion and Li-Pol batteries and communicates via an I²C serial interface. The IC monitors battery capacity, compensating for factors such as battery age, temperature, self-discharge, and discharge rate to provide accurate time-to-empty information across various operating conditions.
