bq2052 - Gas Gauge

Description

The bq2052 Lithium Primary Gas Gauge IC is intended for battery-pack or in-system installation to maintain an accurate record of available battery capacity.

The IC monitors a voltage drop across a sense resistor connected in series with the cells to determine discharge activity of the battery.

Features

  • Accurate measurement of available capacity in Lithium primary batteries such as Lithium Sulphur Dioxide and Lithium Manganese Dioxide.
  • Provides a low-cost battery monitor solution for pack integration - Complete circuit can fit less than 1 square inch of PCB space - Low operating current - Less than 100nA of data retention current.
  • Single-wire communication interface (HDQ bus) for critical battery parameters.
  • Communicates remaining capacity with direct drive.
