Overview

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.

  • Compliant to USB power distribution specifications
  • UL Recognized Component
  • Two completely independent switches
  • Integrated switching matrix supports ACPI S0/S3 state transitions without external FET circuits
  • Make-before-break switching ensures glitch-free transitions
  • No back-feed of auxiliary supply onto main supply dur- ing standby mode
  • Bi-level current-limit preserves auxiliary supply voltage regulation in standby mode
  • Thermally isolated channels
  • Thermal shu
