ADM1069ASTZ

Supervisors Overview

The ADM1069ASTZ is a Super Sequencer supervisory device designed for multi-supply systems. It integrates eight supply fault detectors, four selectable input attenuators, and four dual-function logic inputs. The component features eight programmable driver outputs with configurable open-collector or push-pull modes. Internal circuitry includes a state machine sequencing engine and an integrated 12-bit analog-to-digital converter alongside four 8-bit voltage output digital-to-analog converters. These elements support closed-loop margining by adjusting DC-to-DC converter feedback nodes.

Supervisors Feature Summary

• Integrates eight supply fault detectors providing high-accuracy supervision across multiple voltage rails
• Includes internal 12-bit ADC and four 8-bit DACs to enable closed-loop voltage margining control
• Features a programmable sequencing engine that implements state machine control over driver outputs based on input events

Supervisors Applications

• Supply monitoring and sequencing in complex multi-supply electronic systems
• Closed-loop voltage margining applications utilizing integrated DAC outputs
• Fault event handling and interrupt generation in power management architectures

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure the selected variant matches the required operating temperature range and pin configuration for the target PCB layout.

Supervisors Selection Notes

Select this component when a single-chip solution is required for supervising up to eight supplies with integrated margining capabilities. The inclusion of both ADC and DAC resources eliminates the need for external conversion components in margining designs. Evaluate the programmable driver output configurations to determine if internal charge-pump drive is sufficient for external N-FET switching requirements.

Supervisors Part Context

This part belongs to the Super Sequencer family from Analog Devices, which combines supervisory functions with advanced sequencing logic. Unlike basic supervisors, this series integrates data conversion resources to facilitate active voltage adjustment. The ASTZ suffix typically denotes a lead-free, RoHS-compliant plastic package variant suitable for surface-mount assembly processes.
