bq27621-G1 - System-Side Impedance Fuel Gauge

Datasheet Summary

Description

The Texas Instruments bq27621-G1 is a minimally configured microcontroller peripheral that provides system-side fuel gauging for single-cell Li-Ion batteries.

The device requires very little user configuration and system microcontroller firmware development.

Features

  • 1 Single-Cell Li-Ion Battery Fuel Gauge.
  • Resides on System Board.
  • Supports Embedded or Removable Batteries.
  • Powered Directly from Battery with Integrated LDO.
  • Easy To Configure Fuel Gauging Based on the Dynamic Voltage Correlation Algorithm.
  • Reports Remaining Capacity and State of Charge (SOC) with Smoothing Filter.
  • Automatically Adjusts for Self-Discharge, Temperature, and Rate Changes.
  • Microcontroller Peripheral Supports:.
