Device Overview

Summary

The MIC2537 is a cost-effective high-side power switch with four independently controlled channels, optimized for buspowered Universal Serial Bus (USB) applications. Few external components are necessary to satisfy USB requirements. The MIC2537 satisfies the following USB requirements: each switch channel supplies up to 100mA as required by USB bus-powered downstream devices; fault current is limited to typically 250mA, 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 and 3.3V and 5V logic compatible enable inputs. The MIC2537 is available in active-high and active-low versions in a 16-lead SOP package.
