bq2050H - Low-Cost Lithium Ion Power Gauge

Description

The bq2050H Lithium Ion Power Gauge™ IC is intended for batterypack or in-system installation to maintain an accurate record of available battery capacity.

Features

  • Accurate measurement of available capacity in Lithium Ion batteries.
  • Provides a low-cost battery management solution for pack integration - Complete circuit can fit in as little as 1 2 square inch of PCB - Low operating current (120µA typical) - Less than 100nA of data retention current.
  • High-speed (5kb) single-wire communication interface (HDQ bus) for critical battery parameters.
  • Monitors and controls charge FET in Li-Ion pack protection ci.
