ADM8692ANZ

Supervisors Overview

The ADM8692ANZ is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It provides voltage monitoring and reset signal generation for digital systems. The device operates within a supply voltage range of 3 V to 5.5 V and features a fixed overvoltage threshold of 4.75 V. It includes a reset delay time of 280 ms to ensure stable power-up conditions. The component is housed in an 8-pin PDIP package and supports through-hole mounting. It functions without manual reset or watchdog timer capabilities, drawing a typical operating current of 100 µA.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 4.75 V overvoltage threshold
• Generates reset signals with a defined 280 ms delay for reliable system startup
• Operates on single supply voltages ranging from 3 V to 5.5 V
• Features push-pull output configuration for direct interface with logic circuits

Supervisors Applications

• Microprocessor power supply monitoring
• Battery backup switching circuits
• Embedded system reset management
• Voltage threshold detection in industrial control units

Supervisors Procurement Notes

Verify the exact suffix and package variant when sourcing replacements, as manufacturing revisions may alter pin compatibility or electrical thresholds. Confirm RoHS compliance status and lead times with authorized distributors, as availability for legacy supervisory components can fluctuate. Ensure the selected substitute maintains the same overvoltage threshold and reset delay characteristics to preserve system integrity during power transitions.

Supervisors Selection Notes

Select this component when a fixed overvoltage threshold near 4.75 V is required for 3 V to 5.5 V systems. The 280 ms reset delay suits applications where slow power ramp-up is acceptable. Consider the PDIP-8 package for prototyping or high-reliability through-hole designs. Evaluate if manual reset or watchdog features are needed; if so, alternative models within the ADM86xx series should be reviewed.

Supervisors Part Context

The ADM8692ANZ belongs to the ADM8698 family of improved supervisory circuits designed for enhanced accuracy and reliability compared to earlier generations. It serves as a dedicated voltage monitor for digital logic families requiring stable power rails. The device simplifies design by integrating threshold detection and reset generation into a single low-power package, reducing component count in power management sections.

Supervisors Replacement Considerations

Public confirmed substitutes include the ADM8698ANZ, which offers improved specifications within the same family. Verify that the replacement maintains the 4.75 V overvoltage threshold and compatible PDIP-8 footprint. Cross-reference datasheet revisions to ensure electrical parameters match the original design requirements.
