2. Architecture and Operation of the Multi-Rail Power Sequencer and Monitor Reference Design

Electronic systems that contain FPGAs, CPUs, digital signal processing (DSP) blocks, and ASICs require specific sequences for applying and removing power.

The Multi-Rail Power Sequencer and Monitor reference design provides you the ability to monitor and correctly sequence up to 144 rails—including monitoring VIN—through normal operations, as well as error conditions:

  • Accepts any combination of analog voltage and digital power good input signals.
  • Maps any analog-to-digital converter (ADC) input or power good signal to any monitored VOUT or VIN rail.
