BQ34Z110PWR Description

Short technical summary and product information.

The Texas Instruments BQ34Z110PWR is an advanced fuel gauge IC designed for Lead Acid battery applications. It supports a wide range of battery capacities, from 800 mAh up to 320,000 mAh, and operates with batteries from 4 V to 64 V.

Featuring the patented Impedance Track™ algorithm, this IC provides accurate battery fuel gauging by compensating for aging and self-discharge. It supports charge and discharge currents above 32 A and battery capacities exceeding 65 Ahr. The BQ34Z110PWR includes external NTC thermistor support for temperature monitoring and offers flexible communication interfaces including I2C and HDQ.

Packaged in a 14-TSSOP, the BQ34Z110PWR is suitable for surface mount applications. It operates within an industrial temperature range of -40°C to 85°C. The device supports direct LED display control for one or four LEDs, and can manage displays with five or more LEDs through a port expander. It also includes reduced power modes, with average current consumption as low as 19 µA in full sleep mode.
