ADM9690ARNZ-REEL

Supervisors Overview

The ADM9690ARNZ-REEL is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring microprocessor power supplies. It features a single input channel with an open collector output type and includes a built-in watchdog timer. The device operates within a supply voltage range up to 5.5 V, with a threshold voltage of 4.65 V and an overvoltage threshold of 4.75 V. It provides a reset delay time of 200 ms and consumes 100 uA of operating current. The component is housed in an 8-SOIC package and supports power fail detection. It functions without manual reset or chip enable signals.

Supervisors Feature Summary

• Integrates a voltage monitor comparator and watchdog timer for system supervision
• Provides dedicated reset outputs for reliable microprocessor control
• Supports battery backup switching functionality

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Watchdog timer implementation in industrial controllers

Supervisors Procurement Notes

Verify the specific suffix REEL indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation as environmental standards may vary by production batch. Ensure the supplier provides valid traceability data for this Analog Devices component. Check for obsolescence notices as lifecycle status can impact long-term availability. Validate that the delivered part matches the exact ADM9690ARNZ-REEL designation to avoid pinout or functional mismatches.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog is required for 5V systems. Consider the 8-SOIC package constraints for PCB layout. Evaluate the 100 uA quiescent current against low-power design requirements. Verify that the open collector output suits the downstream logic interface. Assess the 200 ms reset delay against system startup timing needs.

Supervisors Part Context

This part belongs to the ADM9690 series of supervisory circuits from Analog Devices. It is functionally related to the ADM690A but offers distinct specifications tailored for specific monitoring applications. The series focuses on providing robust reset generation and watchdog capabilities for digital systems. The REEL suffix denotes the specific packaging format for automated assembly processes.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Cross-reference with ADM690A only if electrical parameters and pinouts are verified identical through official datasheets. Do not assume interchangeability with other Analog Devices supervisors without explicit manufacturer confirmation.
