The single-cell limit means it won't work with a 2S pack without external balancing. ## I²C bus and package fit Communication runs over I²C, so any MCU with an I²C peripheral can pull the gauge data. No SPI or SMBus translation needed—just two pull-up resistors and the bus lines. The supplier device package is 12-SON (2.5x4 mm), identical to the 12-VFDFN case code. That 2.5x4 mm footprint is tight—confirm the land pattern in the datasheet before layout, especially the pad-to-pad clearance for the exposed centre pad. ROHS3 compliant—no exemptions that would trigger a redesign for EU markets.","metaTitle":"BQ27441DRZT-G1A Fuel Gauge IC – TI Impedance Track","metaDescription":"Texas Instruments BQ27441DRZT-G1A single-cell Li-Ion fuel gauge with Impedance Track, I²C interface, 12-SON package.
