The BQ27500DRZT-V100G4 is a single-cell Li-ion battery monitor from Texas Instruments' Impedance Track™ series, communicating over I²C.
The on-chip over-temperature fault protection triggers before the die exceeds its safe junction limit, which matters when the pack is charging in a hot enclosure.
Texas Instruments lists this part as Active.
It is designed for single-cell (1-series) Lithium Ion packs. The Impedance Track™ algorithm compensates for aging and temperature, so the reported state-of-charge stays accurate across the cell's life without a full-learning cycle.
