Analog Sequencers

Analog sequencers from Analog Devices integrate accurate comparators with the control functionality of power-on and power-down sequencing for voltage regulator banks. The comparators monitor the regulator voltage outputs and trigger the turn on of next rail in the system after a preconfigured time delay. Some members of this portfolio can be cascaded together, which provides scalable solutions to expand functionality across multiple devices. Our analog sequencers provide an easy to use solution for power sequencing challenges in cellular infrastructure, telecommunication, data communication, and data center applications.
