MIC2536 Micrel MIC2536
Dual USB Power Distribution Switch
Final Information General Description Features 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.
The MIC2536 is available in active-high and active-low versions in 8-lead SOP and MSOP. Compliant to USB specifications
