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.
