The Texas Instruments bq27742-G1 is a fuel gauge for single-cell Li-Ion battery packs that uses patented Impedance Track™ technology to deliver rate-, temperature-, and aging-compensated predictions of remaining battery capacity and system runtime with highest accuracy. The device also includes a fully integrated high-side protector that eliminates the need for a separate Li-Ion protection circuit and provides a full suite of high-accuracy fault detections for overvoltage, undervoltage, overcurrent in charge, overcurrent in discharge, and short-circuit in discharge conditions. The hardware protection functions offer built-in data flash-based programmability, allowing simple reconfiguration of existing devices for varying end equipment needs.

The fuel gauge provides information such as remaining battery capacity (mAh), state-of-charge (%), runtime to empty (minutes), voltage (mV), current (mA), and temperature (°C), as well as recording vital parameters throughout the lifetime of the battery. The device also supports interrupts to the host to indicate detection of a variety of important battery conditions to the system.

The DSBGA is a 15-ball package (2.78 mm × 1.96 mm) that is ideal for space-constrained applications.
