BQ34Z653 datasheet

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.

Together with the integrated analog front-end (AFE) short-circuit and overload protection, the bq34z653 maximizes functionality and safety while minimizing external component count, cost, and size in smart battery circuits.


1. Flexible Configuration for 2-Series to 4-Series Li-Ion and Li-Polymer Cells
