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 (SE). 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.
