The MIC2526 is a dual integrated high-side power switch with independent enable and flag functions, optimized for self- powered and bus-powered Universal Serial Bus (USB) appli- cations. 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 require- ments; and a flag output is available to indicate fault condi- tions 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 re- mains 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 ver- sions in 8-pin DIP and SOIC packages.
