The BQ27621YZFR-G1A is a single-cell Lithium-Ion battery fuel gauge integrated circuit from Texas Instruments. It is designed for system-side implementation and communicates via an I2C interface. The device supports battery capacities from 100mAh to 32000mAh and is compatible with 4.2V, 4.3V, and 4.35V Li-Ion chemistries.
A key feature is that it requires no external sense resistor, simplifying the design and reducing BOM cost. The fuel gauge monitors battery parameters and provides accurate state-of-charge information. It operates over a wide temperature range of -40°C to 85°C, making it suitable for various environments.
The IC is housed in a 9-pin DSBGA (YZF) package measuring 1.62mm x 1.58mm with a 0.5mm pitch. The surface-mount package is ideal for space-constrained portable applications. The part is supplied in tape and reel packaging for automated assembly.
