Overview
The ADM1060ARUCS0903R7, produced by Analog Devices Inc., is a programmable supervisory/sequencing device designed to manage multiple power supply faults and sequencing in complex systems. This integrated circuit is particularly useful in central offices, servers, and other infrastructure systems where multiple voltage supplies are required to power different sections of a board. The ADM1060 ensures that these sections power up in the correct sequence to avoid damage, miscommunication, or latch-up.
