【文字介绍】

•It allows battery discharge energy to system when system power demand is temporarily higher than adapter maximum power level and does not crash the adapter.
•Low BOM cost N-channel MOSFETs (ACFET, RBFET, and BATFET) for automatic system power source selection
•Flexibility to program input current, charge current, discharge current, and charge voltage
•System Monitoring and throttle back CPU speed to reduce system power when needed
•Flexibility for different battery configurations
•Meet enegry star requirement
