The MIC2536 is a cost-effective high-side power switch, with two independently controlled channels, optimized for buspowered Universal Serial Bus (USB) applications. Few external components are necessary to satisfy USB requirements.

Each switch channel of the MIC2536 will supply up to 100mA as required for USB bus-powered downstream devices. Fault current is limited to typically 275mA by fast-acting currentlimit circuitry which minimizes voltage droop on the upstream port during fault conditions. A flag output with transient filter indicates fault conditions to the local USB controller but will ignore short flag signals resulting from inrush current during hot plug-in events.

Soft start eliminates the momentary voltage droop on other ports that may occur when the switch is enabled in buspowered applications. Additional features include thermal shutdown to prevent catastrophic switch failure from highcurrent loads and 3.3V and 5V logic compatible enable inputs.Read more
