The Texas Instruments bq27741-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 fuel gauge resides within the battery pack or on the system’s main board with an embedded battery (non-removable). The fuel gauge provides hardware-based over- and undervoltage, overcurrent in charge or discharge, and short-circuit protections.

The fuel gauge 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), as well as recording vital parameters throughout the lifetime of the battery.

The device comes in a 15-ball BGA package (2.776 mm × 1.96 mm) that is ideal for space-constrained applications.
