GENERAL DESCRIPTION

Power-up and power-down sequence control

Fault event handling

Interrupt generation on warnings

The ADM1064 Super Sequencer® is a configurable supervisory/

sequencing device that offers a single-chip solution for supply

monitoring and sequencing in multiple supply systems. In addition

to these functions, the ADM1064 integrates a 12-bit ADC that

can be used to accurately read back up to 12 separate voltages.

Watchdog function can be integrated in SE

Program software control of sequencing through SMBus

12-bit ADC for readback of all supervised voltages

2 auxiliary (single-ended) ADC inputs

Reference input (REFIN) has 2 input options

Driven directly from 2.048 V ( 0.25%) REFOUT pin

More accurate external reference for improved ADC

performance

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

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.

Device powered by the highest of VPx, VH for improved

redundancy

User EEPROM: 256 bytes

For more information about the ADM1064 register map, refer

to the AN-698 Application Note.

Industry-standard 2-wire bus interface (SMBus)

Guaranteed PDO low with VH, VPx = 1.2 V

Available in 40-lead LFCSP and 48-lead TQFP packages

APPLICATIONS

Central office systems

Servers/routers

Multivoltage system line cards

DSP/FPGA supply sequencing

In-circuit testing of margined supplies
