ADM1166

Super Sequencer with Margining Control and Nonvolatile Fault Recording

Analog Devices 

ADM1166

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 also 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.

A block of nonvolatile EEPROM is available that can be used to

store user-defined information and may also be used to hold a

number of fault records that are written by the sequencing engine

defined by the user when a particular fault or sequence occurs.

The device is controlled via configuration data that can be

programmed into an EEPROM. The entire configuration can

be programmed using an intuitive GUI-based software package

provided by Analog Devices, Inc.
