Super Sequencer with Margining Control
and Auxiliary ADC Inputs
Preliminary Technical Data
ADM1069
FEATURES
Complete supervisory and sequencing solution for up to
8 supplies
8 supply fault detectors enable supervision of supplies to
better than 1% accuracy
4 selectable input attenuators allow supervision:
Supplies up to 14.4 V on VH
Supplies up to 6 V on VP1–3
4 dual-function inputs, VX1–4:
High impedance input to supply fault detector with
thresholds between 0.573 V and 1.375 V
General-purpose logic input
8 programmable output drivers (PDO1–8):
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 4 voltage rails
4 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
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 VP1–3, VH for improved
redundancy
User EEPROM: 256 bytes
Industry-standard 2-wire bus interface (SMBus)
Guaranteed PDO low with VH, VPn = 1.2 V
32-lead 7 mm × 7 mm LQFP packages

GENERAL DESCRIPTION
The ADM1069 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 ADM1069 integrates a 12-bit ADC and four 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.
