ADM699ANZ

Supervisors Overview

The ADM699ANZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.65 V for monitoring power rails. The device incorporates a built-in watchdog timer with a reset delay time of 200 ms to ensure system reliability. It draws a typical operating supply current of 1.95 mA and includes overvoltage detection at a threshold of 4.73 V. Designed for through-hole installation, it is housed in an 8-pin PDIP package and functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for automated system recovery
• Provides push-pull output driver capability
• Includes dedicated overvoltage detection functionality

Supervisors Applications

• Microprocessor power supply supervision
• Industrial control system monitoring
• Embedded hardware reset management

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to limited availability status. Confirm package integrity and pin alignment against the PDIP-8 specification before integration. Review manufacturer documentation for handling precautions related to electrostatic discharge sensitivity during assembly processes.

Supervisors Selection Notes

Select this component when a fixed 4.65 V threshold is required for single-input monitoring. Consider the 200 ms reset delay and integrated watchdog features for systems needing basic fault protection without external timing components. Ensure the through-hole PDIP-8 package aligns with the target PCB layout constraints.

Supervisors Part Context

This part belongs to the ADM699 series of supervisory circuits designed for voltage monitoring applications. It serves as a standalone solution for detecting power anomalies in digital systems. The series focuses on providing essential reset generation and watchdog capabilities in a compact form factor suitable for various electronic designs.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same supervisory circuit family. Verify that substitute parts maintain the 4.65 V threshold and 200 ms delay characteristics to ensure functional equivalence in existing designs.
