BQ27426YZFT, Fuel Gauge Li-Ion/Li-Pol 9-Pin DSBGA T/R
BQ27426 System-Side Impedance Track Fuel Gauge
Texas Instruments BQ27426 System-Side Impedance Track™ Fuel Gauge is a single-cell gauge that requires minimal user configuration. With minimal system microcontroller firmware development this leads to quick system bring-up. Three chemistry profiles are pre-programmed 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 a 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. This also provides information such as remaining battery capacity (mAh), state-of-charge (%), and battery voltage (mV).
