General Description
The MIC2524 and MIC2527 are cost-effective high-side power switches with four independently controlled channels, optimized for self-powered and bus-powered Universal Serial Bus (USB) applications. Few external ponents are necessary to satisfy USB requirements. The MIC2524/7 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...
