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 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 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.
The logical core of the device is a sequencing engine. This state
machine-based construction provides up to 63 different states.
This design enables very flexible sequencing of the outputs
based on the condition of the inputs.
The ADM1065 is controlled via configuration data that can be
programmed into an EEPROM. The whole configuration can
be programmed using an intuitive GUI-based software package
provided by Analog Devices, Inc.
