BQ27510-G2 具有直接电池连接功能的系统端 Impedance Track- 电量监测计
BQ27510-G2 描述
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 TrackTM 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
