3.1.1 Combine Power Good Signals

GUID-ED95DB27-80CB-4C4C-9DAE-2C6205DB04A1-low.gifFigure 3-1 Using Logic to Combine Multiple Power-Good Signals
  • Add system indicators without software or system controller interaction
  • Drive low current indicator LEDs (1 mA to 25 mA) with most logic gates
  • Add configurability using logic functions
  • See the Logic Minute video Combining Power Good Signals for more information about this use case
  • See online parametric search tool to find the right AND gate
