ADM692AARNZ

Supervisors Overview

The ADM692AARNZ is a CMOS voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5 V to 5.5 V and monitors a single input channel. The device features an active high push-pull output with a reset delay time of 280 ms. Key specifications include a threshold voltage of 4.4 V, under-voltage threshold of 4.25 V, and over-voltage threshold of 4.5 V. It incorporates a watchdog timer and battery backup switch functionality without manual reset or chip enable signals. The component dissipates up to 500 mW and functions between -40°C and +85°C in an SOIC-8 package.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Battery backup switch capability for power transition management
• Power failure detection circuitry for fault identification
• Active high push-pull output driver configuration

Supervisors Applications

• Microprocessor system supervision
• Portable equipment power management
• Consumer electronics voltage monitoring
• Industrial control system oversight

Supervisors Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance status against current manufacturer documentation. Confirm availability as distribution channels may list this part as obsolete or limited stock. Ensure the SOIC-8 package variant matches design requirements. Cross-reference the exact threshold voltages with the latest datasheet revision to avoid integration errors based on outdated specifications.

Supervisors Selection Notes

Select this component when a single-channel supervisor with active high output is required for 5V systems. The integrated watchdog and battery backup features reduce external component count. Verify that the 280 ms reset delay meets system timing constraints. Ensure the operating temperature range covers the intended application environment. Compare power consumption and package size against alternative supervisory circuits.

Supervisors Part Context

This part belongs to the ADM692A series of voltage supervisors from Analog Devices. It shares functional similarities with other members like the ADM691AARNZ but differs in package type and specific electrical thresholds. The series is designed for cost-effective microprocessor protection in consumer and industrial applications. Related parts may offer different output polarities or additional monitoring channels.
