It communicates over an I²C interface, making it a straightforward addition to a portable-device BOM — no SMBus or SPI host required. The part is specified for one Li-Ion cell only, so a 2S or 4S pack needs a different gauge in the family. The BQ27441DRZT-G1B comes in a 12-VFDFN with an exposed pad (the supplier device package is 12-SON, 2.5x4 mm). This temperature grade covers most portable, handheld, and industrial equipment, but it does not extend to automotive under-hood or engine-bay environments.","metaTitle":"BQ27441DRZT-G1B Battery Fuel Gauge, Impedance Track, I²C","metaDescription":"TI BQ27441DRZT-G1B single-cell Li-Ion battery fuel gauge with Impedance Track™ algorithm.
