CMPWR025 General Description
California Micro Devices&prime 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.
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 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.
For IAPC (Instantly Available Personal Computer) applications see CMD Application Note AP-211 "Instantly Available PCI Card Power Management".
The CMPWR025 is housed in a 8-lead MSOP package and is available with RoHS compliant lead-free finishing.
