系统端Impedance Track电量计,具有动态电压关系 System-Side Impedance Track Fuel Gauge With Dynamic Voltage Correlation
The is a system-side Fuel Gauge with dynamic voltage correlation. It is a minimally configured microcontroller peripheral that provides system-side fuel gauging for single-cell Li-ion batteries. The device requires very little user configuration and system microcontroller firmware development. The bq27621-G1 uses the dynamic voltage correlation algorithm for fuel gauging. This process eliminates the need for a sense resistor when calculating remaining battery capacity mAh, state-of-charge %, battery voltage mV and temperature °C. Battery fuel gauging with the BQ27621-G1 requires connections only to PACK+ P+ and PACK- P- for a removable battery pack or embedded battery circuit.
