Part Number : BQ34Z653
Function : SBS 1.1-Compliant Gas Gauge and Protection Enabled with Impedance Track
Package : TSSOP 44 Pin Type
Maker : Texas Instruments
Pinouts : 
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.
Features
1. Flexible Configuration for 2-Series to 4-Series Li-Ion and Li-Polymer Cells
2. Battery Temperature Heater Control
3. Powerful 8-Bit RISC CPU with Ultralow Power Modes
4. Full Array of Programmable Protection Features
