ADM1069ASTZ-REEL

Supervisors Overview

The ADM1069ASTZ-REEL is a Super Sequencer supervisory device for up to eight supplies. It integrates a 12-bit ADC and four 8-bit DACs for margining. The part features eight supply fault detectors with thresholds from 0.573 V to 1.375 V, four selectable input attenuators, and four dual-function VX inputs. It includes eight programmable driver outputs (PDO1-PDO8) with open-collector or push-pull configurations. A sequencing engine implements state machine control, while an SMBus interface allows software control.

Supervisors Feature Summary

• Integrates a 12-bit analog-to-digital converter and four 8-bit voltage output digital-to-analog converters for closed-loop margining systems.
• Provides complete supervisory and sequencing solution for up to eight supplies with high-accuracy fault detection.
• Features a sequencing engine that implements state machine control of programmable driver outputs based on input events.
• Supports software control of sequencing and interrupt generation through an SMBus interface.

Supervisors Applications

• Supply monitoring and sequencing in multiple supply systems
• Closed-loop margining systems using DAC outputs to adjust DC-to-DC converter feedback nodes
• Complex board power control via state machine sequencing

Supervisors Procurement Notes

Verify the specific suffix ASTZ against official Analog Devices documentation to confirm package type and temperature range. Ensure the REEL designation matches the required tape and reel specifications for automated assembly processes. Cross-reference the full part number with current datasheets to validate availability status and any recent product change notices.

Supervisors Selection Notes

Select this component when a single-chip solution is required for supervising and sequencing up to eight power supplies. Consider the integrated 12-bit ADC and 8-bit DACs if closed-loop margining functionality is necessary. Evaluate the programmable driver outputs and sequencing engine capabilities to determine if they meet the complex state machine requirements of the target application.
