The Texas Instruments BQ27427 battery fuel gauge is a single-cell gauge that requires minimal user-configuration and system microcontroller firmware development, leading to quick system bring-up.

Three chemistry profiles are preprogrammed to enable minimal user-configuration and to help manage user inventory across projects with different battery chemistries. The BQ27427 battery fuel gauge has very low sleep power consumption, leading to longer battery run time. Configurable interrupts help to save system power and free the host from continuous polling. An external thermistor supports accurate temperature sensing.

The BQ27427 battery fuel gauge uses the patented Impedance Track™ algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%), and battery voltage (mV).

Battery fuel gauging with the BQ27427 fuel gauge requires connections only to PACK+ (P+) and PACK– (P–) for a removable battery pack or embedded battery circuit. The tiny, 9-ball, 1.62mm × 1.58mm, 0.5mm pitch NanoFree™ chip scale package (DSBGA) is appropriate for space-constrained applications.
