CMPWR025 - Dual Input SmartOR Power Switch

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.

Features

  • Automatically selects VCC1 OR VCC2 input source.
  • Integrated low impedance switches (0.2Ω TYP).
  • Operating supply range from 2.8V to 5.5V.
  • Glitch-free output during supply switching transitions.
  • Low operating supply current of 20µA (TYP).
  • User-selectable hysteresis for supply selection.
  • 8-pin SOIC Narrow or 8-pin MSOP packages.
