ADM697ARZ-REEL

Supervisors Overview

The ADM697ARZ-REEL is a supervisory circuit manufactured by Analog Devices Inc., designed for monitoring voltage levels in CMOS processes. It features an open-drain output and includes a built-in watchdog timer with a manual reset input capability. The device operates within a supply voltage range up to 5.5 V, with a threshold voltage of 4.65 V and an overvoltage threshold of 4.73 V. It provides a reset delay time of 200 ms and supports battery backup switching. The component is housed in a 16-SOIC package, suitable for surface mount installation, and functions across a temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer with manual reset functionality for system reliability
• Provides open-drain reset output compatible with CMOS logic
• Supports battery backup switching for continuous monitoring during power transitions

Supervisors Applications

• Monitoring 5V CMOS process integrated circuits
• System supervision in embedded electronics requiring watchdog protection
• Power management circuits needing battery backup detection

Supervisors Procurement Notes

Verify the specific suffix REEL against official Analog Devices documentation to confirm tape-and-reel packaging configuration. Ensure compatibility with existing board layouts for 16-SOIC packages. Cross-reference the part number with current product change notices or obsolescence announcements, as availability status may vary by region. Confirm that the open-drain output requirements align with the target system's pull-up resistor design.

Supervisors Selection Notes

Select this component when a dedicated supervisory circuit with integrated watchdog timing is required for 5V systems. The open-drain output necessitates external pull-up resistors, which must be accounted for in the design. Consider the 200 ms reset delay and 4.65 V threshold against the specific power rail characteristics of the application. Verify that the manual reset input feature meets the system's recovery requirements.

Supervisors Part Context

The ADM697 belongs to the ADM69x series of supervisory circuits from Analog Devices, focusing on voltage monitoring and system reset generation. This series typically offers various threshold options and output configurations to suit different microcontroller and FPGA applications. The ARZ designation indicates a lead-free, RoHS-compliant variant in a standard industrial temperature range package.
