BQ20Z70PWR Description

Short technical summary and product information.

The BQ20Z70PWR from Texas Instruments is an SBS 1.1-compliant gas gauge integrated circuit that utilizes patented Impedance Track technology for accurate battery charge monitoring. Designed for Li-ion and Li-polymer battery packs, it measures and maintains an accurate record of available charge.

 

This IC monitors critical battery parameters such as capacity change, impedance, and open-circuit voltage, reporting information to the system host controller via a serial communication bus. It supports 2 to 4 series Li-ion and Li-polymer cells and operates within a temperature range of -40°C to 85°C. The BQ20Z70PWR features an SMBus interface and includes full array of programmable protection features for voltage, current, and temperature.

 

Packaged in a 20-TSSOP, the BQ20Z70PWR is suitable for surface mount applications. It is designed to work with the bq29330 analog front-end (AFE) protection IC to provide a complete pack electronics solution. Key applications include notebook PCs, medical and test equipment, and portable instrumentation.
