MIC2525 - USB Power Control Switch Not Recommended for New Designs

Datasheet Summary

Description

The MIC2525 is an integrated high-side power switch, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications.

Few external components are necessary to satisfy USB requirements.

Features

  • include thermal shutdown to prevent catastrophic switch failure from high-current loads, undervoltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present, and 3.3V and 5V logic compatible enable inputs. The MIC2525 is a UL recognized component and is available in active-high and active-low versions in 8-pin DIP and SOIC packages. Features.

MIC2525 Micrel MIC2525 USB Power Control Switch Not Recommended for New Designs Refer to MIC2025 General Description The MIC2525 is an integrated high-side power switch, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. Few external components are necessary to satisfy USB requirements. The MIC2525 satisfies the following USB requirements: each switch channel supplies up to 500mA as required by USB downstream devices; the switch’s low on-resistance meets USB voltage drop requirements; fault current is limited to typically 750mA, well below the UL 25VA safety requirements; and a flag output is available to indicate fault conditions to the local USB controller.
