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 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.
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.
