The Texas Instruments bq27531-G1 system-side Li- Ion Battery Management Unit is a microcontroller peripheral that provides Impedance Track fuel gauging and charging control for single-cell Li-Ion battery packs. The device requires little system microcontroller firmware development. Together with the bq2419x Single-Cell Switched-Mode Charger, the bq27531-G1 manages an embedded battery (nonremovable) or a removable battery pack.

The bq27531-G1 uses the patented Impedance Track algorithm for fuel gauging, and provides information such as remaining battery capacity (mAh), state-ofcharge (%), run time to empty (minimum), battery voltage (mV), temperature (°C), and state of health (%).

Battery fuel gauging with the bq27531-G1 requires only PACK+ (P+), PACK– (P–), and Thermistor (T) connections to a removable battery pack or embedded battery circuit. The CSP option is a 15-pin package in the dimensions of 2.61 mm × 1.96 mm with a 0.5-mm lead pitch, which is ideal for spaceconstrained applications.
