General Description

The bq34z653 SBS-compliant gas gauge and protection IC, incorporating patented Impedance Track™ technology, is a single IC solution designed for battery-pack or in-system installation.

The bq34z653 measures and maintains an accurate record of available charge in Li-Ion or Li-Polymer batteries using its integrated high-performance analog peripherals.

The bq34z653 monitors capacity change, battery impedance, open-circuit voltage, and other critical parameters of the battery pack, which reports the information to the system host controller over a serial-communication bus.

Key Features

  • 1 Next Generation Patented Impedance Track™ Technology Accurately Measures Available Charge in Li-Ion and Li-Polymer Batteries.
  • Better than 1% Error over the Lifetime of the Battery.
  • Supports the Smart Battery Specification SBS v1.1.
  • Flexible Configuration for 2-Series to 4-Series LiIon and Li-Polymer Cells.
  • Battery Temperature Heater Control.
  • Powerful 8-Bit RISC CPU with Ultralow Power Modes.
  • Full Array of Programmable Protection Fe.
