Overview
The ADM1060ARUCS0703R7, produced by Analog Devices Inc., is a programmable supervisory/sequencing device designed to manage multiple power supply fault detection and sequencing in complex systems. This device is particularly useful in central office systems, servers, and infrastructure network boards where multiple voltage supplies need to be monitored and sequenced. The ADM1060 offers a single-chip solution for these requirements, ensuring that different sections of a board power up in the correct order to avoid damage, miscommunication, or latch-up.
