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. SMBus and single-wire DQ communication interfaces are both available.

Together with the integrated analog front-end (AFE) short-circuit and overload protection, the bq34z950 maximizes functionality and safety while minimizing external component count, cost, and size in smart battery circuits.
