ADM8616MCYAKSZ-RL7

Supervisors Overview

The ADM8616MCYAKSZ-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 maximum supply voltage of 5.5 V and features a threshold voltage of 4.63 V for undervoltage detection, with an overvoltage threshold of 4.75 V. The device provides a push-pull output type and includes a watchdog timer function. It supports a minimum reset timeout of 140 ms and lacks manual reset or battery backup switch capabilities. The component functions across a temperature range of -40°C to +85°C, consumes 20 µA of operating current, and is housed in a SC-70-4 surface-mount package.

Supervisors Feature Summary

• Monitors power supply voltage levels and ensures code execution integrity in microprocessor-based systems
• Generates power-on reset signals when supply voltage rises to the preset threshold level
• Integrates a watchdog timer to detect software failures and system hangs

Supervisors Applications

• Microprocessor-based system power monitoring
• Code execution integrity verification
• Low voltage supervisory circuits

Supervisors Procurement Notes

Verify availability status as distribution channels may indicate limited stock or discontinuation. Confirm RoHS compliance details through official documentation. Ensure the SC-70-4 package matches design constraints. Validate the 4.63 V threshold against system requirements. Check for any regional sales restrictions before ordering.

Supervisors Selection Notes

Select this component for applications requiring precise voltage supervision with integrated watchdog functionality. The low quiescent current of 20 µA suits battery-sensitive designs. Verify that the 4.63 V threshold aligns with the target rail voltage. Consider the SC-70-4 footprint for space-constrained PCB layouts. Ensure the operating temperature range meets environmental specifications.
