The Texas Instruments BQ27426 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 minimum user-configuration, and to help manage customer
inventory across projects with different battery chemistries. The BQ27426 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 via an external thermistor.
The BQ27426 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 BQ27426
fuel gauge requires connections only to PACK+ (P+) and PACK– (P–) for a removable
battery pack or embedded battery circuit. The tiny, 9-ball, 1.62 mm × 1.58 mm, 0.5
mm pitch NanoFree™ chip scale package (DSBGA) is ideal for space-constrained
applications.
