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.
