The Texas Instruments BQ34Z100PW-G1 is a versatile, multi-chemistry battery fuel gauge IC designed for accurate capacity estimation using its patented Impedance Track™ technology. This device supports a wide range of battery chemistries including Lead Acid, Li-Ion/Li-Polymer, LiFePO4, NiCd, and NiMH.
Key electrical specifications include support for battery capacities from 100 mAh up to 32000 mAh, and charge/discharge currents up to 32 A. The operating voltage range is from 3 V to 65 V. It features low average operating currents in normal, sleep, and full sleep modes, making it suitable for power-sensitive applications.
Communication with the host system is handled via HDQ or I2C interfaces. The BQ34Z100PW-G1 also supports external NTC thermistor input for temperature monitoring and includes SHA-1/HMAC authentication for security. It can directly control one to four LEDs for capacity indication or interface with port expanders for higher LED counts.
Packaged in a 14-pin TSSOP, the BQ34Z100PW-G1 is designed for surface mount applications. Its operating temperature range is -40°C to 85°C, ensuring reliable performance in various environmental conditions. This fuel gauge is ideal for applications requiring precise battery monitoring and management across diverse battery types.
