Description for the BQ27505-J5

The Texas Instruments bq27505-J5 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 micro-controller firmware development. The bq27505-J5 resides on the system's main board and manages an embedded battery (nonremovable) or a removable battery pack.

The bq27505-J5 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 bq27505-J5 requires only PACK+ (P+), PACK- (P-), and Thermistor (T) connections to a removable battery pack or embedded battery circuit. The CSP option is a 12-ball package in the dimensions of 2.43mm × 1.96mm with 0.5mm lead pitch. It is ideal for space constrained applications.
