Part details & applications

The ADM1062 Super Sequencer^® is a configurable supervisory/sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple-supply systems. In addition to these functions, the ADM1062 integrates a 12-bit ADC and six 8-bit voltage output DACs. These circuits can be used to implement a closed-loop margining system that enables supply adjustment by altering either the feedback node or the reference of a dc-to-dc converter using the DAC outputs.

For more information about the ADM1062 register map, refer to the AN-698 Application Note.

APPLICATIONS

Central office systems
Servers/routers
