ADM693AARW-REEL

Supervisors Overview

The ADM693AARW-REEL is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single power supply rails. It operates within a maximum supply voltage of 5.5 V and features a threshold voltage of 4.4 V with an overvoltage threshold of 4.5 V. The device includes a watchdog timer, battery backup switch, and power-fail detection capabilities. It offers open-drain and push-pull output types with a reset delay time of 280 ms. Operating current is 100 uA, and it functions between -40°C and +85°C in a 16-pin SOIC package.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability
• Battery backup switching functionality
• Power-fail detection capability
• Chip enable signal support

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify component authenticity through official Analog Devices channels or authorized distributors. Confirm the specific suffix indicates reel packaging. Check for obsolescence status as this family may be discontinued. Ensure RoHS compliance documentation matches current regulatory requirements. Validate pinout compatibility with existing PCB layouts before procurement.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog is required. Consider the 4.4 V threshold for standard 5V logic systems. Evaluate the 280 ms reset delay against processor startup times. Compare power consumption at 100 uA against low-power alternatives if battery life is critical. Verify SOIC-16 footprint availability in the design.

Supervisors Part Context

This part belongs to the ADM693A series of supervisory circuits from Analog Devices. It shares functional similarities with other members like the ADM693AARN but differs in packaging and reel configuration. The series provides essential protection for digital systems by detecting under-voltage and over-voltage conditions while managing reset sequences.
