CMPWR025

Dual Input SmartOR™ Power Switch

FEATURES

APPLICATIONS

• Automatically selects V_CC1OR V_CC2input 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.
