Super Sequencer™ with Margining Control

and Auxiliary ADC Inputs

ADM1066

FEATURES

Complete supervisory and sequencing solution for up to

10 supplies

10 supply fault detectors enable supervision of supplies to

better than 1% accuracy

5 selectable input attenuators allow supervision:

Supplies up to 14.4 V on VH

Supplies up to 6 V on VP1–4

5 dual-function inputs, VX1–5:

High impedance input to supply fault detector with

thresholds between 0.573 V and 1.375 V

General-purpose logic input

10 programmable output drivers (PDO1–10):

Open collector with external pull-up

Push/pull output, driven to VDDCAP or VPn

Open collector with weak pull-up to VDDCAP or VPn

Internally charge-pumped high drive for use with external

N-FET (PDO1–6 only)

Sequencing engine (SE) implements state machine control of

PDO outputs:

State changes conditional on input events

Enables complex control of boards

Power-up and power-down sequence control

Fault event handling

Interrupt generation on warnings

Watchdog function can be integrated in SE

Program software control of sequencing through SMBus

Complete voltage margining solution for 6 voltage rails

6 voltage output 8-bit DACs (0.300 V to 1.551 V) allow

voltage adjustment via dc/dc converter trim/feedback

node

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 2.048V (±0.25%) REFOUT pin

More accurate external reference for improved ADC

performance

Device powered by the highest of VP1–4, VH for improved

redundancy

User EEPROM: 256 bytes

Industry-standard 2-wire bus interface (SMBus)

Guaranteed PDO low with VH, VPn = 1.2 V

40-lead 6 mm × 6 mm LFCSP and

48-lead 7 mm × 7 mm TQFP packages

GENERAL DESCRIPTION

The ADM1066 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 ADM1066 integrates a 12-bit ADC and six 8-bit

voltage output DACs. These circuits can be used to implement a

closed-loop margining system, which enables supply adjustment

by altering either the feedback node or reference of a dc/dc

converter using the DAC outputs.
