bq27320 - Single-Cell CEDV Fuel Gauge

General Description

The Texas Instruments single-cell bq27320 battery fuel gauge requires very minimal configuration and system microcontroller firmware development, leading to quick system bring-up.

Key Features

  • 1 Battery Fuel Gauge For System-/Pack-Side Configuration.
  • Compensated End-of-Discharge Voltage (CEDV) Gauging Technology.
  • Adjusts for Battery Aging, Self-Discharge, Temperature, and Rate Changes.
  • Reports Remaining Capacity, State-of-Charge (SOC), and Time-to-Empty with Smoothing Filter.
  • Battery State-of-Health Estimation.
  • Supports Embedded or Removable Packs from 100-mAhr to 14,500-mAhr Capacity.
  • Accommodates Pack Swapping with up to.
