Overview
The ADM1060ARU from Analog Devices Inc. is a programmable supervisory/sequencing device designed to provide a single-chip solution for multiple power supply fault detection and sequencing in communications systems. It is particularly useful in central offices, servers, and other infrastructure systems where multiple power supplies are required. The device ensures that different sections of a board power up in a specific order to avoid damage, miscommunication, or latch-up.
