ADM6315-44D2ARTZR7

Supervisors Overview

The ADM6315-44D2ARTZR7 is a voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5 V to 5 V and features an open-drain output type. The device provides manual reset functionality without an integrated watchdog timer or battery backup switch. It utilizes a SOT-143-4 package for surface mount installation. The component includes a reset delay time of 28 ms and supports a maximum power supply voltage of 5.5 V.

Supervisors Feature Summary

• Provides open-drain microprocessor supervisory monitoring
• Supports manual reset input functionality
• Designed for single-input voltage supervision

Supervisors Applications

• Microprocessor system reset circuits
• Voltage level monitoring in embedded systems
• Power supply supervision for portable electronics

Supervisors Procurement Notes

Verify the specific threshold voltage corresponding to the '44' suffix against official Analog Devices documentation before procurement, as this parameter defines the trip point. Confirm that the SOT-143-4 package dimensions match your PCB footprint requirements. Ensure the open-drain output configuration aligns with your downstream logic interface needs. Cross-reference the exact part number spelling to avoid confusion with similar variants in the ADM6315 family.

Supervisors Selection Notes

Select this component when a fixed threshold voltage near 4.4 V is required for system supervision. The open-drain output allows for flexible pull-up voltage selection, accommodating various logic levels. The absence of a watchdog timer simplifies design if external timing control is preferred. Verify that the 28 ms reset delay meets the startup timing requirements of the monitored processor or memory devices.

Supervisors Part Context

This part belongs to the ADM6315 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and output configurations in compact packages. The ADM6315-44D2ARTZR7 specifically denotes a variant with a defined threshold voltage and open-drain output. It is designed for reliable operation in standard industrial and commercial temperature ranges.

Supervisors Replacement Considerations

Check for direct equivalents such as MAX6315 variants with matching threshold voltages and output types. Ensure any substitute maintains the SOT-143-4 package and open-drain output capability. Verify that the replacement part's reset delay and operating voltage range are compatible with the existing design constraints.
