Replaced By BQ27510-G2 – The device is an EXACT EQUIVALENT in functionality and parametrics to the compared device.
TI does not recommend using this part in a new design. This product continues to be in production to support existing customers.
The Texas Instruments bq27510 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 resides on the system's main board and manages an embedded battery (non-removable) or a removable battery pack.
The bq27510 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 requires only PACK+ (P+), PACK- (P-), and Thermistor (T) connections to a removable battery pack or embedded battery.
