MIC2010/MIC2070  
USB Power Controller  
General Description  
Features  
• Compliant to USB power distribution specifications  
• Two completely independent switches  
• Integrated switching matrix supports ACPI S0/S3 state  
transitions without external FET circuits  
• Make-before-break switching ensures glitch-free  
transitions  
The MIC2010 is a dual channel USB power switch designed  
to support the power distribution requirements for USB  
Wakeup from the ACPI S3 state. The MIC2010 will directly  
switch its two outputs between a 5V main supply and a  
5V auxiliary supply normally provided in ATX style power  
supplies.  
• No back-feed of auxiliary supply onto main supply  
during standby mode  
• Bi-level current-limit preserves auxiliary supply voltage  
regulation in standby mode  
• Thermally isolated channels  
• Thermal shutdown protection  
• Fault status outputs with filter prevents false assertions  
during hot-plug events  
• Circuit breaker options with auto-reset (MIC2070)  
• Undervoltage lockout  
The MIC2010 will adjust its current-limit threshold according  
to the ACPI state it is in. In the normal active ACPI S0 state  
the current-limit is set at 500mA minimum per channel  
satisfying the USB continuous output current specification.  
In the S3 state the current-limit can be reduced to a value  
determined by an external resistor to minimize the current  
that is supplied by the auxiliary supply, thereby ensuring that  
voltage regulation is maintained even during fault conditions.  
The MIC2010 provides make-before-break switching to  
ensure glitch-free transitions between the S3 and S0 states.  
Each channel is also thermally isolated from the other so that  
a fault in one channel does not effect the other. FAULT status  
output signals are also provided indicating overcurrent and  
thermal shutdown conditions.  
• UL File #179633  
Applications  
• Desktop PCs  
The MIC2070 option latches the output off upon detecting an  
overcurrent condition lasting for more than 5ms minimum.  
TheoutputcanberesetbyeithertogglingtheENinputsofthe  
MIC2070-1/-2 or by removing the load. Latching the output  
off provides a circuit breaker mode of operation which  
reduces power consumption during fault conditions.

• Notebook docking stations  
• LAN Servers
