GENERAL DESCRIPTION

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.

State changes conditional on input events

Enables complex control of boards

Power-up and power-down sequence control

Fault event handling

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.

Interrupt generation on warnings

Watchdog function can be integrated in SE

Program software control of sequencing through SMBus

Device powered by the highest of VPx, VH for improved

redundancy

User EEPROM: 256 bytes

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.

Industry-standard 2-wire bus interface (SMBus)

Guaranteed PDO low with VH, VPx = 1.2 V

Available in 32-lead, 7 mm × 7 mm LQFP

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.

APPLICATIONS

Central office systems

Servers/routers

Multivoltage system line cards

DSP/FPGA supply sequencing

In-circuit testing of margined supplies

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.
