Overview
The ADM1060ARU-REEL, produced by Analog Devices Inc., is a programmable supervisory/sequencing device designed for multiple power supply fault detection and sequencing in communications systems. It offers a single-chip solution for managing complex power supply requirements in central offices, servers, and other infrastructure systems. The device ensures that different sections of a board, such as logic circuits, DSP cores, and DSP I/O circuits, power up in a controlled and sequenced manner to avoid damage, miscommunication, or latch-up.
