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.
Supply margining can be performed with a minimum of external components. The margining loop can be used for in-circuit testing of a board during production （for example， to verify board functionality at −5% of nominal supplies）， or it can be used dynamically to accurately control the output voltage of a dc-to-dc converter.
The device also provides up to 10 programmable inputs for monitoring undervoltage faults， overvoltage faults， or out-of-window faults on up to 10 supplies. In addition， 10 programmable outputs can be used as logic enables. Six of these programmable outputs can also provide up to a 12 V output for driving the gate of an N-FET that can be placed in the path of a supply.
