BQ34Z100PWR-G1 Description

Short technical summary and product information.

The Texas Instruments BQ34Z100PWR-G1 is a versatile standalone fuel gauge IC designed for multi-chemistry battery applications. It employs the patented Impedance Track™ algorithm for accurate capacity estimation across a voltage range of 3 V to 65 V. This device supports various battery chemistries including Lead Acid, Li-Ion/Li-Polymer, LiFePO4, NiCd, and NiMH.

 

Key electrical specifications include support for battery capacities up to 29 Ah and charge/discharge currents up to 32 A. Communication with the host system is handled via HDQ or I2C interfaces. The IC operates within a temperature range of -40°C to 85°C and features reduced power modes for efficiency, with average operating current as low as <30 µA in full sleep mode.

 

Packaged in a 14-TSSOP, the BQ34Z100PWR-G1 is suitable for surface mount applications. It offers features like aging compensation, self-discharge compensation, and external NTC thermistor support. The device also includes SHA-1/HMAC authentication for security and direct control for LED displays.
