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 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  
400mtypical 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.
