Overview
The ADM1060ARUCS0403R7, produced by Analog Devices Inc., is a programmable supervisory/sequencing device designed to manage multiple power supply fault detection and sequencing in communications systems. This device is particularly useful in central offices, servers, and other infrastructure systems where multiple power 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.
