PRODUCT DESCRIPTION
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.
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.
APPLICATIONS
PCI cards for Wake-On-LAN/Wake-On-Ring
Dual power systems
Systems with standby capabilities
Battery backup systems
See Application Note AP211
C0970500
PIN DIAGRAM, TYPICAL APPLICATION CIRCUIT, AND SIMPLIFIED BLOCK DIAGRAM
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 the CAMD Applications Note AP211
“Instantly Available PCI Card Power Management”.
