Trackers

Analog Devices trackers cover a wide range of 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 in a specific order, either based on a specified time delay or an event (for example, voltage tracking). Our trackers feature the use of external N-channel control MOSFETs to minimize power loss and integrated remote sense switches to compensate for series voltage drops in the wiring.
