bq27320 Single-Cell Battery Fuel Gauge Texas Instruments bq27320 Single-Cell Battery Fuel Gauge requires very minimal configuration and system microcontroller firmware development, leading to quick system bring-up. The bq27320 uses a Compensated End-of-Discharge Voltage (CEDV) gas gauging algorithm for fuel gauging. This provides information such as remaining battery capacity (mAh), state-of-charge (%), runtime-to-empty (min), battery voltage (mV), temperature (°C), and state-of-health (%). Configurable interrupts on the Texas Instruments bq27320 help save system power and free the host from continuous polling. Accurate temperature sensing is supported via an external thermistor.
