ADM1067ACPZ

Supervisors Overview

The ADM1067ACPZ is a configurable supervisory and sequencing device designed for multi-supply systems. It integrates ten supply fault detectors with selectable input attenuators, enabling supervision of voltages up to 14.4 V on the VH pin and up to 6 V on VPn pins. The component features ten programmable output drivers (PDOs) capable of open-collector, push-pull, or high-drive configurations. A built-in sequencing engine manages state machine control based on input events. Additionally, it includes six 8-bit voltage output DACs for open-loop margining applications.

Supervisors Feature Summary

• Integrates ten supply fault detectors with selectable input attenuators for comprehensive multi-rail monitoring
• Features a sequencing engine that implements state machine control of programmable output drivers
• Includes six 8-bit voltage output DACs to enable open-loop margining via DC-to-DC converter adjustment

Supervisors Applications

• Supply monitoring and sequencing in multiple supply systems
• Open-loop margining systems using integrated DAC outputs
• Complex board power control via sequencing engine state machines

Supervisors Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm package type and temperature range. Confirm availability status as distribution channels may list limited stock or end-of-life notices. Ensure the ordering part number matches the required LFCSP package variant. Cross-reference datasheet revisions to validate electrical characteristics before procurement.

Supervisors Selection Notes

Select this component when a single-chip solution for both supervision and sequencing is required. It is suitable for designs needing precise voltage monitoring across multiple rails with varying thresholds. The inclusion of DACs makes it appropriate for applications requiring voltage margining without external controllers. Evaluate the need for the integrated sequencing engine versus discrete logic solutions.

Supervisors Part Context

The ADM1067 belongs to the Super Sequencer family from Analog Devices. This series provides complete supervisory and sequencing solutions for complex power architectures. The device consolidates functions typically requiring multiple discrete components into a single integrated circuit, simplifying board layout and design complexity.

Supervisors Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Verify compatibility of pinouts and electrical specifications if considering cross-model replacements within the same family.
