What is a power sequencer?
Essentially each outlet on the back of a power sequencer will turn on in a spaced sequence a few seconds apart after you turn on the main power. Then they reverse the process when you power down.
Do audiophiles use power conditioners?
Then you have the high-end conditioners, usually with some sort of sophisticated filtering to remove the hash between the notes and the overall quietness of the system. Many audiophiles use these. Then you have the high-end power strips that are only expensive outlets, wired together with expensive wire.
Why does Power Sequencing need to be used?
Power sequencing is an essential part of any design, especially in complex systems that utilize multiple power rails. Today’s high-performance processing devices, such as FPGAs, ASICs, PLDs, DSPs, ADCs, and microcontrollers, require multiple voltage rails just to power their own internal circuitry, such as the core, memory, and I/O.
Why do you need a power sequencer for a power supply?
Whether your system has two voltage rails or dozens, we have a power sequencer to fit your requirements. Power sequencing is an essential part of any design, especially in complex systems that utilize multiple power rails.
What does the ucd90x power supply sequencer do?
The UCD90x family of digital power supply sequencers, also known as system health monitors, provides a comprehensive digital solution for complex power systems: Configurable power-up and power-down sequence control for up to 24 power rails based on timing and/or dependencies (rail and/or pin)
How to control power up and power down sequence?
We offer the easiest method to control the power up and power down sequence of multiple power supplies. Discrete solutions with a combination of resistors and capacitors can provide power-up sequencing, but by themselves cannot provide a reverse sequence during power down. The LM3880 and LM3881 simple power supply sequencers offer:
