ADM699ARZ

Supervisors Overview

The ADM699ARZ is a CMOS supervisory circuit manufactured by Analog Devices Inc. housed in a 16-lead SOIC package. It monitors a single input voltage with a threshold of 4.65 V and an overvoltage threshold of 4.73 V. The device operates within a supply voltage range of 3 V to 5.5 V, drawing 1.95 mA of quiescent current. It features a push-pull output, a watchdog timer, and a reset delay time of 200 ms. The component supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrated watchdog timer for system reliability monitoring
• Push-pull output driver configuration
• Single-channel voltage supervision capability

Supervisors Applications

• Embedded system power management
• Microcontroller reset circuits
• Industrial control systems

Supervisors Procurement Notes

Verify the specific suffix 'ARZ' against official Analog Devices documentation to confirm RoHS compliance status and lead-free packaging specifications. Confirm availability status as the part may be subject to limited supply or end-of-life conditions. Ensure the selected variant matches the required thermal and electrical parameters for the target application environment.

Supervisors Selection Notes

Select this component when a dedicated supervisor with an integrated watchdog timer is required for 5V CMOS systems. Verify that the 4.65 V threshold aligns with the monitored rail. Consider the 200 ms reset delay and 1.95 mA current consumption relative to system power budgets. Ensure the SOIC-16 package fits the PCB layout constraints.

Supervisors Part Context

The ADM699ARZ belongs to the ADM699 series of supervisory circuits designed for monitoring power supplies in digital systems. It provides essential protection by detecting under-voltage and over-voltage conditions while managing system resets through its built-in watchdog functionality.

Supervisors Replacement Considerations

Consult official Analog Devices documentation for confirmed substitute part numbers. Verify pinout compatibility and parameter equivalence before substitution.
