bq27411-G1 - Single-Cell Li-Ion Battery Fuel Gauge

Datasheet Summary

Description

The Texas Instruments bq27411-G1 device is a battery fuel gauging solution for single-cell Li-Ion battery packs.

The device requires minimal configuration and uses One Time Programmable (OTP) Non-Volatile Memory (NVM) to avoid an initialization download by the system processor.

Features

  • 1 Single-Cell Li-Ion Battery Fuel Gauge.
  • Resides in Battery Pack.
  • Low-Value External Sense Resistor (10 mΩ Typical).
  • One Time Programmable (OTP) Configuration Non-Volatile Memory (NVM).
  • Powered Directly from Battery with Integrated LDO.
  • 400-kHz I2C™ Serial Interface.
  • Internal Temperature Sensor or Host-reported Temperature.
  • Battery Fuel Gauging Based on Patented Impedance Track™ Technology.
  • Reports Remaining Capacit.
