ADM8616RCYAKSZ-RL7

Supervisors Overview

The ADM8616RCYAKSZ-RL7 is a supervisory circuit manufactured by Analog Devices Inc., designed to monitor power supply voltage levels and code execution integrity in microprocessor-based systems. It operates within a supply voltage range of 1 V to 5.5 V and features a threshold voltage of 4.63 V with an overvoltage threshold of 4.75 V. The device provides a push-pull output type and includes a watchdog timer function without manual reset or battery backup switching capabilities. It is housed in a SC-70-4 package, supports surface mount installation, and functions across a temperature range of -40°C to +85°C while consuming 20 µA of operating current.

Supervisors Feature Summary

• Monitors power supply voltage levels and ensures code execution integrity in microprocessor-based systems
• Generates power-on reset signals when the supply voltage rises to a preset threshold level
• Integrates a watchdog timer for system reliability without requiring manual reset inputs

Supervisors Applications

• Microprocessor-based system power monitoring
• Code execution integrity verification
• Power-on reset signal generation

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or official channels. Confirm the specific suffix matches the required electrical parameters, as variations exist within the ADM8616 family. Check for end-of-life status or limited availability notices from the manufacturer before finalizing procurement plans.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for single-input voltage supervision. Ensure the application does not need manual reset functionality or battery backup switching. Verify that the SC-70-4 package fits the design constraints and that the 20 µA quiescent current meets power budget requirements.

Supervisors Part Context

This part belongs to the ADM8616 series of supervisory circuits from Analog Devices. These devices are categorized under PMIC - Power Management ICs and specifically serve as processor supervisors. The series is designed for low-voltage applications requiring reliable voltage monitoring and system reset management.

Supervisors Replacement Considerations

Check for ADM8616 variants with different threshold voltages if the 4.63 V specification is not suitable. Verify pinout compatibility with the SC-70-4 package before substituting with other supervisory ICs.
