bq27320 System-Side Fuel Gauge with Integrated LDO Evaluation Module



  • Extremely simple setup and configuration
  • Chemistry parameters can be self-tuned by customer without needing TI's support
  • Configurable interrupts save system power and frees up host from continuous polling

Texas Instruments  BQ27320EVM-766

The Texas Instruments bq27320 system-side li-ion battery fuel gauge is a microcontroller peripheral that provides fuel gauging for single-cell li-ion battery packs. The device requires minimal system microcontroller firmware development. The bq27320 uses the compensated end-of-discharge voltage gas gauging algorithm for fuel gauging, and provides information such as remaining battery capacity, state-of-charge, run-time to empty, battery voltage, temperature and state of heatlh.
