ADM692AARN

Supervisors Overview

The ADM692AARN is a microprocessor supervisory circuit manufactured by Analog Devices Inc., housed in an SOIC-8 surface-mount package. It monitors a single voltage input with a threshold of 4.4 V and features an active high output type. The device includes a watchdog timer, battery backup switchover, and power-fail warning capabilities. It operates within a supply voltage range of 4.5 V to 5.5 V, drawing 100 uA of working current. The reset delay time is specified at 280 ms, with an overvoltage threshold of 4.5 V and an undervoltage threshold of 4.25 V. It functions between -40 C and +85 C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Provides automatic backup battery switchover functionality
• Detects power failures via dedicated warning signals

Supervisors Applications

• Microprocessor system supervision
• Battery backup power management
• Power failure detection circuits

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinued status. Confirm RoHS compliance details as documentation indicates non-compliance in some records. Validate package integrity and pin configuration against the SOIC-8 specification before integration into designs requiring this specific legacy part.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold is required for CMOS process ICs. Ensure the active high output aligns with downstream logic requirements. Consider the 280 ms reset delay duration relative to system startup timing needs. Verify that the 100 uA operating current fits the low-power design constraints of the target application environment.

Supervisors Part Context

This part belongs to the ADM692A series of voltage supervisory circuits designed for 5V CMOS applications. It serves as a specialized power management IC within the broader PMIC category. The device is distinct from similar models like the ADM691AARNZ which utilizes a different package and threshold specifications.
