MIC2010 Description
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.
