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.
