MIC2010 - USB Power Controller

General 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.

Key Features

  • Compliant to USB power distribution specifications.
  • 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 during standby mode.
  • Bi-level current-limit preserves auxiliary supply voltage regulation in standby mode.
  • Thermally isolated channels.

MIC2010/2070 MIC2010/MIC2070 USB Power Controller Micrel General 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. In the normal active ACPI S0 state the current-limit is set at 500mA minimum per channel satisfying the USB continuous output current specification.
