MIC2536  
Dual USB Power Distribution Switch  
Preliminary Information  
General Description  
Features  
The MIC2536 is a cost-effective high-side power switch, with  
two independently controlled channels, optimized for bus-  
poweredUniversalSerialBus(USB)applications. Fewexter-  
nal components are necessary to satisfy USB requirements.  
• Compliant to USB specifications  
• 2.7V to 5.5V operating range  
• 150mA minimum continuous load current per channel  
• 400mΩ typical on-resistance  
• Fast-acting short circuit protection with  
thermal shutdown  
• Integrated filter eliminates  
Each switch channel of the MIC2536 will supply up to 100mA  
asrequiredforUSBbus-powereddownstreamdevices.Fault  
current is limited to typically 275mA by fast-acting current-  
limit 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.  
false overcurrent flag assertions  
• Individual open-drain fault flag pins with transient filter  
• 3V/5V-compatible enable inputs  
• Active-high (-1) and active-low (-2) versions  
• Reverse-current blocking in off mode (no “body diode”)  
• Soft-start circuit  
• 100µA maximum on-state supply current  
• <1µA typical off-state supply current  
• –40°C to 85°C operation  
Soft start eliminates the momentary voltage droop on other  
ports 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.  
Applications  
• USB keyboard bus-powered hubs  
• USB bus-powered docking stations  
• Note Book PCs  
The MIC2536 is available in active-high and active-low ver-  
sions in 8-lead SOP and MSOP.  
• PDAs  
• General purpose power distribution applications  
• PC board hot swap  
• Inrush current-limiting
