CMPWR025 Overview
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.
CMPWR025 Key Features

- Operating supply range from 2.8V to 5.5V
- Glitch-free output during supply switching
- Low operating supply current of 20µA (TYP)
- User-selectable hysteresis for supply selection
- 8-pin SOIC Narrow or 8-pin MSOP packages
CMPWR025 Applications
- PCI cards for Wake-On-LAN/Wake-On-Ring
