GENERAL DESCRIPTION

The ADM1065 Super Sequencer? is a configurable supervisory/sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple-supply systems.

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 each 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.
