MIC2546/2547  
Dual Programmable Current Limit Switch  
Preliminary Information  
General Description  
Features  
The MIC2546 and MIC2547 are integrated high-side dual  
powerswitchesoptimizedforlowlossdcpowerswitchingand  
other power management applications, including Advanced  
Configuration and Power Interface (ACPI). The MIC2546/47  
isacost-effective, highlyintegratedsolutionthatrequiresfew  
external components to satisfy USB and ACPI requirements.  
2.7V to 5.5V input  
Adjustable current-limit up to 1.5A  
Reverse current flow blocking (no body diode)  
100µA typical on-state supply current per channel  
2µA typical off-state supply current  
120mmaximum on-resistance  
Open-drain fault flag  
Loadcurrentmanagementfeaturesincludeaprecisionresis-  
tor-programmable output current-limit and a soft-start circuit  
which minimizes inrush current when the switch is enabled.  
Thermal shutdown, along with current-limit, protects the  
switch and the attached device.  
Thermal shutdown  
Thermal shutdown output latch (MIC2547)  
2ms (slow) turn-on and fast turnoff  
Available with active-high or active-low enable  
Applications  
USB power distribution  
PCI Bus Power Switching  
Notebook PC  
ACPI power distribution  
PC card hot swap applications  
Inrush current-limiting  
The MIC2546/47’s open-drain flag outputs are used to indi-  
catecurrent-limitingorthermalshutdowntoalocalcontroller.  
The MIC2547 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, andisalsousedasthethermalshutdownlatchresetfor  
the MIC2547.  
The MIC2546 and MIC2547 are available in active-high and  
active-low enable versions in 16-pin TSSOP and SOP  
packages.
