GENERAL DESCRIPTION

Power-up and power-down sequence control

Fault event handling

Interrupt generation on warnings

The ADM1065 Super Sequencer® is a configurable supervisory/

sequencing device that offers a single-chip solution for supply

monitoring and sequencing in multiple-supply systems.

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

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 each 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.

User EEPROM: 256 bytes

Industry-standard 2-wire bus interface (SMBus)

Guaranteed PDO low with VH, VPx = 1.2 V

Available in 40-lead, 6 mm × 6 mm LFCSP and

48-lead, 7 mm × 7 mm TQFP packages

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.

APPLICATIONS

Central office systems

Servers/routers

Multivoltage system line cards

DSP/FPGA supply sequencing

In-circuit testing of margined supplies

The ADM1065 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.
