MIC2545A/2549A  
Programmable Current-Limit  
High-Side Switch  
General Description  
Features  
The MIC2545A and MIC2549A 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  
2.7V to 5.5V input  
Adjustable current-limit up to 3A  
Reverse current flow blocking  
90µA typical on-state supply current  
1µA typical off-state supply current  
50mmaximum on-resistance  
Open-drain fault flag  
MIC2545A/49A is  
a
cost-effective, highly-integrated  
solution that requires few external components to satisfy  
USB and ACPI requirements.  
Load current management features include a precision,  
resistor-programmable output current-limit and a soft-start  
circuit, which minimizes inrush current when the switch is  
enabled. Thermal shutdown, along with adjustable current-  
limit, protects the switch and the attached device.  
Thermal shutdown  
Thermal-shutdown output latch (MIC2549A)  
2ms (slow) soft-start turn-on, fast turnoff  
Available with active-high or active-low enable  
The MIC2545A/49A’s open-drain flag output is used to  
indicate current-limiting or thermal shutdown to a local  
controller. The MIC2549A has an additional internal latch  
which 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 MIC2549A.  
Applications  
USB power distribution  
PCI Bus Power Switching  
Notebook PC  
ACPI power distribution  
PC card hot swap applications  
Inrush current-limiting  
The MIC2545A and MIC2549A are available in active-high  
and active-low enable versions in 8-pin DIP, SOIC, and  
TSSOP packages.
