Texas Instruments bq27546-G1 Li-Ion Battery Fuel Gauge
Texas Instruments bq27546-G1 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 for accurate battery fuel gauging. The bq27546-G1 resides within the battery pack or on the system's main-board with an embedded battery. This device uses the patented Impedance Track™ algorithm for fuel gauging. Texas Instruments bq27546-G1 Gauge provides information such as remaining battery capacity, state-of-charge, run-time to empty, battery voltage, and temperature. It also provides detections for internal short or tab disconnection events.
