MIC2525  
USB Power Control Switch  
Not Recommended for New Designs  
Refer to MIC2025  
General Description  
Features  
The MIC2525 is an integrated high-side power switch, opti-  
mized for self-powered and bus-powered Universal Serial  
Bus (USB) applications. Few external components are nec-  
essary to satisfy USB requirements.  
• Compliant to USB specifications  
• UL Recognized Component  
• 3V to 5.5V input  
• 500mA minimum continuous load current per port  
• 140mΩ maximum on-resistance  
• 1.25A maximum short circuit current limit  
• Open-drain fault flag pins  
• 110µA typical on-state supply current  
• 1µA typical off-state supply current  
• Output can be forced higher than input (off-state)  
• Thermal shutdown  
• 2.4V typical undervoltage lockout (UVLO)  
• 1ms turn-on (soft-start) and fast turnoff  
• Active-high or active-low enable versions  
• 8-pin SOIC and DIP packages  
TheMIC2525satisfiesthefollowingUSBrequirements:each  
switch channel supplies up to 500mA as required by USB  
downstream devices; the switch’s low on-resistance meets  
USB voltage drop requirements; fault current is limited to  
typically 750mA, well below the UL 25VA safety require-  
ments; and a flag output is available to indicate fault condi-  
tions to the local USB controller. Soft start eliminates the  
momentaryvoltagedropontheupstreamportthatmayoccur  
when the switch is enabled in bus-powered applications.  
Additional features include thermal shutdown to prevent  
catastrophic switch failure from high-current loads,  
undervoltage lockout (UVLO) to ensure that the device re-  
mains off unless there is a valid input voltage present, and  
3.3V and 5V logic compatible enable inputs.  
Applications  
• USB hosts and self-powered hubs  
• USB bus-powered hubs  
The MIC2525 is a UL recognized component and is available  
in active-high and active-low versions in 8-pin DIP and SOIC  
packages.  
• Hot plug-in power supplies  
• Battery-charger circuits  
For new designs, please see the MIC2025/2075.
