MIC2526 General Description
The MIC2526 is a dual integrated high-side power switch with independent enable and flag functions, optimized for selfpowered and bus-powered Universal Serial Bus (USB) applications. Few external components are necessary to satisfy USB requirements.
The MIC2526 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. Soft start eliminates the momentary voltage drop on the upstream port that may occur when the switch is enabled in bus-powered applications.
Additional 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 MIC2526 is available in active-high and active-low versions in 8-pin DIP and SOIC packages.
