MIC2012 Datasheet Usb Power Controller

Manufacturer: Micrel Semiconductor

Overview: MIC2012 MIC2012/MIC2072 USB Power Controller Micrel General.

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.

The MIC2012 will adjust its current-limit threshold according to the ACPI state it is in.

Key Features

  • 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.
