1.1. Features of the Reference Design

The Multi-Rail Power Sequencer and Monitor reference design has the following features:

  • The design can control the enable sequence of up to 143 output rails.
  • The design can draw from a mix of power good input signals (POK) and monitored voltage rails.
  • You can base the power sequencing on voltages reaching a threshold or on timed events.
  • You can distribute the design across multiple MAX® 10 devices to increase the number of monitored voltage rails.

These are some of the options, among many others, that the reference design provides:

  • Parameterizable levels of glitch filtering on power good or voltage inputs
  • Customizable retry responses
  • Comprehensive PMBus* interface
  • Customizable non-volatile event and Black Box fault logging to assist with debug
