The bq27545-G1 Li-ion battery fuel gauge is a microcontroller
peripheral that provides fuel gauging for single-cell Li-Ion battery packs. The device requires
little system microcontroller firmware development for accurate battery fuel gauging. The
bq27545-G1 resides within the battery pack or on the system’s main-board with an
embedded battery (non removable).
The bq27545-G1 uses the patented Impedance Track™ algorithm for fuel
gauging, and provides information such as remaining battery capacity (mAh), state-of-charge (%),
run-time to empty (minimum), battery voltage (mV), and temperature (°C). It also provides
detections for internal short or tab disconnection events.
The bq27545-G1 also features integrated support for secure battery pack
authentication, 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 constrained applications.
