GENERAL DESCRIPTION
The ADM1064 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 ADM1064 integrates a 12-bit ADC that
can be used to accurately read back up to 12 separate voltages.
The device also provides up to 10 programmable inputs for moni-
toring 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
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.
For more information about the ADM1064 register map, refer
to the AN-698 Application Note.
