  • Integrated Low Impedance Switches (0.2 W TYP).
  • Operating Supply Range from 2.8 V to 5.5 V.
  • Provides Up to 600 mA Output Current.
  • Glitch.
  • Free Output During Supply Switching Transitions.
  • Low Operating Supply Current of 20 mA (TYP).
  • User.
  • Selectable Hysteresis for Supply Selection.
  • 8.
  • Pin MSOP Package.
  • These Devices are Pb.
  • Free and are RoHS Compliant.

CMPWR025 Dual Input SmartORt Power Switch Product Description The SmartORt 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. Hysteresis is built in (and is user selectable) to prevent switch chatter. The CMPWR025 is a much−improved solution over simply ORing two diodes, due to the greatly reduced losses of the CMPWR025 when compared to low forward drop Schottky diodes. The CMPWR025 is designed to operate above the 1 W (375 mA at 3.3 V) sleep mode rating stated in the PCI Rev 2.2 spec.
