ADM6316CY46ARJZ-R7

Supervisors Overview

The ADM6316CY46ARJZ-R7 is a supervisory circuit from Analog Devices designed to monitor power supply voltage levels and code execution integrity in microprocessor-based systems. It features a fixed reset threshold voltage of 4.63 V with an accuracy of 2.5%. The device provides a manual reset input and utilizes an open-drain active low reset output stage. It operates within a supply voltage range up to 5.5 V and consumes 20 μA of working current. The component supports a watchdog timer with a typical timeout of 1600 ms and offers a reset delay time of 200 ms. It is specified for industrial temperature ranges from -40°C to +85°C and is housed in a 5-lead SOT-23 package.

Supervisors Feature Summary

• Integrates a watchdog timer to detect code execution failures and assert resets if the input is not strobed within the preset period.
• Includes a manual reset input allowing external assertion of the reset signal via push-button or other control mechanisms.
• Provides glitch immunity against power supply transients to ensure stable operation during voltage fluctuations.

Supervisors Applications

• Microprocessor systems requiring reliable power supervision
• Controllers needing watchdog functionality for system stability
• Portable equipment with limited power budgets

Supervisors Procurement Notes

Verify the specific suffix CY46 confirms the 4.63 V threshold and open-drain output configuration. Ensure the RJZ-R7 designation matches the required RoHS compliance and reel packaging format. Cross-reference the manufacturer part number with official Analog Devices documentation to confirm availability and lead times before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required alongside manual reset capability. The open-drain output suits applications where wired-OR configurations are necessary. Consider the 20 μA quiescent current for battery-operated designs. Verify that the 200 ms reset delay meets the target system's startup timing requirements.

Supervisors Part Context

This part belongs to the ADM6316/ADM6317/ADM6318/ADM6319/ADM6320/ADM6321/ADM6322 family of supervisory circuits. These devices share common features such as watchdog timers and manual reset inputs but differ in output stages, threshold voltages, and timeout options. The ADM6316 variant specifically combines a watchdog input with a manual reset input.

Supervisors FAQ
