BQ27541DRZR TI Battery Fuel Gauge | 12-SON (2.5x4) | Impedance Track, I2C

Product Overview

The BQ27541DRZR is a highly integrated, single-cell Li-Ion battery fuel gauge IC from Texas Instruments. It uses the patented Impedance Track™ technology to provide accurate battery state-of-charge (SOC) and state-of-health (SOH) information over the lifetime of the battery. The device is housed in a compact 12-pin SON package (2.5mm x 4mm) and communicates via I2C interface, making it ideal for space-constrained portable applications.
