GENERAL DESCRIPTION
The ADM1063 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 ADM1063 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
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 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 ADM1063 register map,
refer to the AN-698 Application Note.
