... MIC2012 General Description The MIC2012 is a dual channel USB power switch designed to support the power distribution requirements for USB Wakeup from the ACPI S3 state. The MIC2012 will directly switch its two outputs between a 5V main supply and a 5V auxiliary supply normally provided in ATX style power supplies. ...

... MAIN 5V Main Supply (Input): All MAIN inputs must be connected together exter- nally. OUT1 Channel 1 (Output): For MIC2012-1, -2 both pins must be externally con- nected together. EN2 Enable (Input): Channel 2, active-high (–1) or active-low (–2). Toggling this input also resets the latched output of the MIC2072. ...

... MOSFET switch from the AUX input to each of its two outputs. Conversely when the S3# input is HIGH (S0 state) the MIC2012/72 will switch a 100mΩ, 500mA MOSFET switch from the MAIN input to each of its two outputs. The lower current limit during the ACPI S3 state helps to ensure that the standby supply maintains regulation even during fault conditions ...
