ADM6318BX49ARJZ-R7

Supervisors Overview

The ADM6318BX49ARJZ-R7 is a single-channel power supply management circuit manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40 °C to +85 °C and utilizes a 5-pin SOT-23 package (PDSO5). The device features a fixed reset threshold voltage of 4.9 V with no adjustability. It includes a manual reset input and provides push-pull active low output stages. The component is RoHS compliant, lead-free, and designed for supervisory applications in microprocessor systems.

Supervisors Feature Summary

• Integrated watchdog timer for monitoring code execution integrity
• Manual reset input capability for external assertion
• Push-pull active low reset output stage configuration

Supervisors Applications

• Microprocessor systems
• Computers
• Controllers
• Intelligent instruments
• Portable equipment

Supervisors Procurement Notes

Verify the specific suffix 'R7' corresponds to the reel packaging format required for your assembly line. Confirm that the 4.9 V threshold matches your system's voltage requirements. Ensure the SOT-23-5 footprint aligns with your PCB design. Check for RoHS compliance documentation if required by your manufacturing standards. Validate the manual reset pin functionality against your schematic.

Supervisors Selection Notes

Select this part when a fixed 4.9 V supervision level is required. The push-pull output drives loads directly without open-drain pull-ups. The manual reset feature allows hardware-initiated resets. Verify compatibility with the 2.5 V to 5 V operating range. Consider the 5 μA quiescent current for low-power designs.

Supervisors Part Context

This component belongs to the ADM631x series of supervisory circuits from Analog Devices. These devices monitor power supply voltage and code execution. The series offers various combinations of watchdog inputs, manual resets, and output configurations. The ADM6318 specifically integrates a watchdog timer and manual reset with a push-pull output.

Supervisors Replacement Considerations

Substitutes within the ADM631x family must match the 4.9 V threshold and push-pull output type. Verify pinout compatibility for the SOT-23-5 package. Ensure the replacement supports the same industrial temperature range and manual reset functionality.
