Product Introduction
The bq27546-G1 lithium-ion battery gas gauge is a microcontroller peripheral that provides fuel gauging functionality for single-cell lithium-ion battery packs. The device requires minimal system microcontroller firmware development to achieve accurate battery fuel gauging. The bq27546-G1 can be installed inside the battery pack or on the system motherboard of a device with an embedded (non-removable) battery.
The bq27546-G1 uses the patented Impedance Track™ algorithm for fuel gauging and provides information such as remaining battery capacity (mAh), state of charge (%), remaining run time (min.), battery voltage (mV), and temperature (℃). It can also detect internal short circuits or tab disconnection events.
The bq27546-G1 has built-in support for secure battery authentication using the SHA1/HMAC authentication algorithm. The device comes in a 15-ball Nano-Free™ DSBGA package (2.61 mm x 1.96 mm), making it ideal for space-constrained applications.
