Single cell Impedance Track™ pack side fuel gauge with DSBGA packagePower management
The bq27546-G1 Li-Ion battery fuel gauge is a microcontrollerperipheral that provides fuel gauging for single-cell Li-Ion battery packs. The device requiresminimal system microcontroller firmware development for accurate battery fuel gauging. Thebq27546-G1 resides within the battery pack or on the system’s main-board with anembedded battery (non-removable).
The bq27546-G1 uses the patented ImpedanceTrack™ algorithm for fuel gauging, and provides information such as remaining batterycapacity (mAh), state-of-charge (%), run-time to empty (min.), battery voltage (mV), andtemperature (°C). It also provides detections for internal short or tab disconnectionevents.
The bq27546-G1 features integrated support for secure battery packauthentication, using the SHA-1/HMAC authentication algorithm.
The device comes in a 15-ball Nano-Free™ DSBGA package(2.61 mm × 1.96 mm) that is ideal for space-constrainedapplications.
