Product details

Single-cell Li-Ion fuel gauge with Impedance Track

The BQ27500DRZR-V130 is a battery monitor IC for single-cell Lithium Ion packs. It uses TI's Impedance Track™ algorithm to report remaining capacity, state-of-charge, and voltage — the algorithm learns the battery's impedance over time, so accuracy holds up as the cell ages and across temperature swings, unlike a simple voltage-based gauge that drifts with load. Communication is over a standard I²C interface, which means any MCU with an I²C peripheral can read the gauge data without a dedicated SPI port or proprietary bus.

Supplied in a 12-VFDFN Exposed Pad package, with the supplier device package 12-SON (2.5x4).

The base product number is BQ27500 — the -V130 suffix identifies the specific firmware version. Confirm the firmware revision matches your host-side algorithm before committing the BOM line. No stock-holding claim — lead time and pricing confirmed at quote time through our distribution network.

Frequently asked questions

What is the difference between BQ27500 and BQ27501?

The BQ27500 and BQ27501 are both single-cell Impedance Track fuel gauges, but they use different firmware algorithms and host-side drivers. The BQ27500-V130 is a specific firmware variant; the BQ27501 targets a different host-interface command set. They are not pin-compatible drop-in replacements — the host firmware must match the gauge firmware version.

How does the Impedance Track algorithm work?

Impedance Track learns the battery's impedance by measuring voltage, current, and temperature during charge and discharge cycles. It updates the model continuously, so the reported state-of-charge stays accurate as the cell ages and across load and temperature changes — unlike a voltage-based gauge that requires periodic full-cycle recalibration.
