The Texas Instruments BQ27510-G3 system-side 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. The BQ27510-G3 resides on the system’s main board and manages an embedded battery (non-removable) or a removable battery pack.

The BQ27510-G3 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 (min.), battery voltage (mV), temperature (°C) and state-of-health (%).

Battery fuel gauging with the BQ27510-G3 requires only PACK+ (P+), PACK– (P–), and optional Thermistor (T) connections to a removable battery pack or embedded battery circuit.
