Product details

Single-cell fuel gauge with Impedance Track

The Texas Instruments BQ27750DRZR is a single-cell battery protection IC and fuel gauge built around the Impedance Track™ algorithm, designed for Lithium Ion and Lithium Polymer packs. It monitors voltage, current, and temperature to report state-of-charge and provides fault protection for overcurrent, overtemperature, overvoltage, and short-circuit conditions. Communication with a host microcontroller runs over an I²C interface.

Package and temperature grade

Housed in a 12-VFDFN exposed-pad package (supplier device package 12-SON, 2.5x4 mm), this part is surface-mount and requires a thermal pad on the PCB for heat sinking.

Lifecycle status — obsolete

The BQ27750DRZR is listed as obsolete by Texas Instruments. Buyers should confirm availability and current pricing at quote time.

Frequently asked questions

Is BQ27750DRZR compatible with single cell lithium polymer batteries?

Yes. The BQ27750DRZR is designed for single-cell (1-series) Lithium Ion and Lithium Polymer chemistries, with fault protection covering overcurrent, overtemperature, overvoltage, and short circuit.
