The BQ34Z100PWR is a multi-chemistry battery monitor from Texas Instruments, designed for accurate fuel gauging in battery packs. It supports Li-Ion, Li-Polymer, and LiFePO4 chemistries with 1 to 16 series cells. The device integrates the Impedance Track algorithm for precise capacity estimation over time and temperature. It accommodates battery capacities from 800 mAh to 320 Ah and charge/discharge currents above 32 A. Communication with the host system is via two-wire I2C or single-wire HDQ interfaces. The BQ34Z100PWR includes SHA-1/HMAC based authentication for battery security and provides one- or four-LED direct display control, or five-LED and higher via port expander. Average current consumption is less than 140 µA in normal operation, 64 µA in sleep mode, and 19 µA in full sleep mode. Operating temperature range is -40°C to 85°C. The IC is housed in a 14-TSSOP package (0.173", 4.40mm Width) for surface mount assembly.
