Supply Sequencers

Analog Devices analog and digital supply sequencers cover a wide range of power supply sequencing needs for systems with multiple power rails, including complex systems that utilize FPGAs, ASICS, PLDs, DSPs, data converters (ADCs or DACs), and microcontrollers. These high performance components may demand that certain rails power-up and/or power-down. Our supply sequencers are easy to design in, accurate, and cascadable, which allows designers to quickly architect reliable systems with hundreds of rails in any type of application. Standout features include charge pumped gate drives for MOSFETs in series with supplies, externally configurable timers, integrated supply supervisors, and a host of digital inputs/outputs for simple communications.
