DESCRIPTION

The Texas Instruments bq27510-G2 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-G2 resides on the system’s main board and manages an embedded battery (non-removable) or a removable battery pack.

The bq27510-G2 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), and temperature (°C)

Battery fuel gauging with the bq27510-G2 requires only PACK+ (P+), PACK– (P–), and Thermistor (T)connections to a removable battery pack or embedded battery.
