USB Power Controller
The MIC2010 is a dual channel USB power switch designed to support the power distribution requirements for USB Wakeup from the ACPI S3 state. The MIC2010 will directly switch its two outputs between a 5V main supply and a 5V auxiliary supply normally provided in ATX style power supplies.
The MIC2010 will adjust its current-limit threshold according to the ACPI state it is in. In the normal active ACPI S0 state the current-limit is set at 500mA minimum per channel satisfying the USB continuous output current specifi.
