Manufacturer: Texas Instruments

Overview: bq34z950 www.ti.com SLUSBF0A – APRIL 2013 – REVISED MAY 2013 SBS 1.

General Description

The bq34z950 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 bq34z950 measures and maintains an accurate record of available charge in Li-Ion or Li-Polymer batteries using its integrated high-performance analog peripherals.

The bq34z950 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.
  • 2 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.
