Power Backup Management

Power Backup Management

Safety Features Application

Power Backup management is used when a designer must guarantee the non-interrupted power supply of a system from different sources.

 

 

Necessary Components

  • Any GreenPak with three ACMPs.
  • External resistor dividers to attenuate input signal to the operating value range of ACMPs.

Design Steps

  1. Use three ACMPs to detect power input signals.
  2. Use CNT/DLY blocks configured as a Delay to implement a debounce filter.
  3. Add logic cells to create switching priority between input sources.
