MIC2544/48  
Programmable Current-Limit High-Side Switch  
Features  
General Description  
• 2.7V to 5.5V Input  
The MIC2544 and MIC2548 are integrated, high-side  
power switches optimized for low-loss DC power  
switching and other power management applications,  
including Advanced Configuration and Power Interface  
(ACPI). The MIC2544/48 are cost-effective, highly  
integrated solutions that require few external  
components to satisfy USB and ACPI requirements.  
• Adjustable Current-Limit up to 1.5A  
• Reverse Current Flow Blocking (No “Body Diode”)  
• 75 μA Typical On-State Supply Current  
• 1 μA Typical Off-State Supply Current  
• 120 mMaximum On-Resistance  
• Open-Drain Fault Flag  
Load current management features include a precision  
• Thermal Shutdown  
resistor-programmable output current-limit and  
a
soft-start circuit that minimizes inrush current when the  
switch is enabled. Thermal shutdown, along with  
current-limit, protects the switch and the attached  
device.  
• Thermal Shutdown Output Latch (MIC2548)  
• 2 ms (Slow) Turn-On and Fast Turn-Off  
• Available with Active-High or Active-Low Enable  
Applications  
The MIC2544/48’s open-drain flag output is used to  
indicate current-limiting or thermal shutdown to a local  
controller. The MIC2548 has an additional internal latch  
that turns the output off upon thermal shutdown,  
providing robust fault control. The enable signal is  
compatible with both 3V and 5V logic, and is also used  
as the thermal shutdown latch reset for the MIC2548.  
• USB Power Distribution  
• PCI Bus Power Switching  
• Notebook PC  
• ACPI Power Distribution  
• PC Card Hot Swap Applications  
• Inrush Current-Limiting  
The MIC2544 and MIC2548 are available in active-high  
and active-low enable versions in the 8-pin SOIC and  
8-pin MSOP packages.
