ADM8691ARWZ

Supervisors Overview

The ADM8691ARWZ is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring power supply voltages up to 5V with a maximum operating supply of 5.5V. It features an active-high output driver and includes programmable clock functionality alongside power-fail detection capabilities. The device operates within a temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP surface-mount package.

Supervisors Feature Summary

• Integrates programmable clock generation for system timing control
• Provides dedicated power-fail detection signals for reliable monitoring
• Features active-high output driver configuration

Supervisors Applications

• Microprocessor reset circuits requiring precise voltage supervision
• Battery-powered systems utilizing backup switching mechanisms
• Industrial control boards needing power-fail signal generation

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to potential counterfeit risks. Confirm RoHS compliance status via official documentation before integration. Ensure the specific suffix matches design requirements as packaging variations may exist. Check current lifecycle status as availability may be limited.

Supervisors Selection Notes

Select this component when an active-high output is required rather than open-drain configurations found in similar series members. Consider the integrated programmable clock feature if external timing components are undesirable. Verify that the 5V monitoring threshold aligns with the target system voltage rails.

Supervisors Part Context

This part belongs to the ADM8691 supervisory circuit family from Analog Devices, which focuses on voltage monitoring solutions. It shares functional similarities with other ADM86xx series devices but distinguishes itself through its specific output polarity and clock integration options.

Supervisors Replacement Considerations

ADM8691ARUZ is a verified pin-compatible alternative offering the same supervisory functions in a TSSOP-16 package.
