bq27421-G1 - System-Side Impedance Track Fuel Gauge

Datasheet Summary

Description

The Texas Instruments bq27421-G1 fuel gauge is a minimally configured microcontroller peripheral that provides system-side fuel gauging for single-cell LiIon 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.
Low-Value Integrated Sense Resistor (7 mΩ, Typical).
Easy-to-Configure Fuel Gauging Based on Patented Impedance Track™ Technology.
Reports Remaining Capacity and State-ofCharge (SOC) with Smoothing Filter.
Automatically Adjusts for Battery Aging, SelfDischarge, Tempera.
