Description
General part information
BQ27427 Series
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 customer 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 save system power and free up the host from continuous polling. Accurate temperature sensing is supported with an external thermistor.
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).
