It communicates over an I²C bus, making it straightforward to integrate with a host MCU in portable equipment.
The 12-VFDFN exposed-pad package (12-SON, 2.5x4 mm) keeps the footprint small and the thermal pad helps conduct heat from the gauge and sense resistor into the PCB copper pour.
TI lists the BQ27500DRZR-V100 as Active.
The BQ27500DRZR-V100 and BQ27500DRZR-V110 are both single-cell Li-Ion monitors in the same Impedance Track™ family, but the V110 variant typically carries a different firmware version or chemistry profile. Pin-compatibility and footprint are identical, so a BOM swap is possible if the host firmware is updated to match the gauge's algorithm version. Confirm the exact firmware revision with the datasheet before substituting.
No. The BQ27500DRZR-V100 is designed for single-cell (1S) Lithium Ion packs only. For a 2-series stack, look at the BQ27520 or BQ40Z50 family, which include cell balancing and stack-voltage measurement.
