Product details

Single-cell Li-Ion fuel gauge with Impedance Track™

The Texas Instruments BQ27541DRZR-V200 is a single-cell Li-Ion battery fuel gauge from the Impedance Track™ series, communicating over an I²C interface. It monitors state-of-charge and reports battery data to a host controller in portable equipment. The device operates across -40°C to 85°C, suiting it for outdoor handhelds, medical monitors, and industrial instrumentation where the battery pack sees ambient extremes.

I²C bus and host integration

The BQ27541DRZR-V200 uses the I²C interface to deliver battery parameters — voltage, current, temperature, remaining capacity — to a system MCU. A single-cell Li-Ion pack is the target; the gauge handles one series cell. Over-temperature fault protection is built in, which can trigger a host alert or shutdown if the pack exceeds a safe threshold.

Package and board footprint

Surface-mount assembly with standard reflow profile; the small SON footprint saves board area in tight battery-pack or handheld designs.

Lifecycle and supply position

It is a current-production TI part, so production BOMs are not facing an imminent last-time-buy.

Frequently asked questions

What is the difference between BQ27541DRZR-V200 and BQ27541DRZR-V100?

The V200 and V100 are firmware-version variants of the same base BQ27541 fuel gauge. The V200 carries a later production firmware release with updated Impedance Track™ algorithms. Both are pin-compatible and share the same I²C interface, package, and single-cell Li-Ion chemistry support. The V200 is the more current revision for new designs.

What is the BQ27541DRZR-V200 used for?

It is a single-cell Li-Ion battery fuel gauge that reports state-of-charge, voltage, current, and temperature over an I²C bus. Typical applications include portable medical devices, handheld instruments, and battery-powered industrial equipment where accurate remaining-capacity data is needed.
