Multi-Rail Power Sequencer and Monitor

The Multi-Rail Power Sequencer and Monitor is a highly parameterizable set of intellectual property (IP) blocks that can be customized to meet your power sequencing needs. It does the following: 

• Controls the enable sequence of up to 143 output rails
• Can be distributed across multiple Intel® MAX® 10 devices to increase the number of monitored channels
• Allows any combination of power good inputs and monitored voltage rails.

The sequencing can be based on voltages reaching a certain threshold and timed events. It offers parameterizable levels of glitch filtering on power good or voltage inputs, customizable retry responses, a comprehensive Power Management Bus (PMBus*) interface, and numerous other options to tailor the sequencer to the needs of your application.

• Sequence and monitor any combination of up to 144 rails:
• Up to 18 voltage-monitored rails per Intel® MAX® 10 device
• Up to 144 digital-monitored power good rails
• Monitor overvoltage, undervoltage, and power good status
• Easily configurable via Platform Designer GUI
• Compliant agent interface: PMBus* v1.2 
• Programmable noise filtering on analog input samples and debouncing (28 delay levels) of digital power good inputs
• Latch all warning and fault conditions until cleared
• Set defaults and dynamically control levels for overvoltage, undervoltage, and power good
• Programmable response behavior for overvoltage and undervoltage events
• Configurable delays between sequencing of rails, the qualification window, discharge, and retries
• Cascade or instantiate multiple times within the same device as independent controllers
• Validate behavior with the included simulation test bench
