ADM1168:  Super Sequencer and Monitor with Nonvolatile Fault Recording

Product Details

Product Status:Recommended for New Designs

The ADM1168 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 eight programmable inputs for monitoring undervoltage faults, overvoltage faults, or out-of-window faults on up to eight supplies. In addition, eight 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 NFET 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 ADM1168 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.

For more information about the ADM1168 register map, refer to the AN-721 Application Note.
