ADM1066ACP - Brand New Analog Devices Supervisors
-
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.
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
