CALIFORNIA MICRO DEVICES  
CMPWR025  
Dual Input SmartOR™ Power Switch  
FEATURES  
APPLICATIONS  
• Automatically selects VCC1 OR VCC2 input source  
• Integrated low impedance switches (0.2Ω TYP)  
• Operating supply range from 2.8V to 5.5V  
• PCI cards for Wake-On-LAN/Wake-On-Ring  
• Dual power systems  
• Systems with standby capabilities  
• Battery backup systems  
• Glitch-free output during supply switching  
transitions  
• See Application Note AP211  
• Low operating supply current of 20µA (TYP)  
• User-selectable hysteresis for supply selection  
• 8-pin SOIC Narrow or 8-pin MSOP packages  
PRODUCT DESCRIPTION  
The CMPWR025 is designed to operate above the 1W  
(375mA at 3.3V) sleep mode rating stated in the PCI  
Rev 2.2 spec. In fact the CMPWR025 current rating is  
dependent upon the power dissipation resulting from the  
voltage drop across the internal switch elements. See  
the Typical DC Characteristics section in this data sheet  
for details.  
California Micro Devices’ SmartOR™ CMPWR025 is a  
dual input power switch that selects between two  
different power inputs and delivers it to one output. The  
device integrates two very low impedance power  
switches and automatically implements an OR function  
that selects the higher of the two inputs. A hysteresis is  
built in (and is user selectable) to prevent switch chatter.  
For IAPC (Instantly Available Personal Computer)  
applications see the CAMD Applications Note AP211  
“Instantly Available PCI Card Power Management”.  
The CMPWR025 is a much-improved solution to simply  
ORing two diodes, due to the greatly reduced losses of  
the CMPWR025 when compared to low forward drop  
Schottky diodes.
