ADM6315-45D2ARTRL7

Supervisors Overview

The ADM6315-45D2ARTRL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage input and provides an open-drain reset output with a threshold voltage of 4.5V. The device features a manual reset input, a fixed reset delay time of 28 ms, and operates within a supply voltage range of 2.5 V to 5 V. It is housed in a compact SOT-143-4 surface-mount package and supports a maximum supply voltage of 5.5 V.

Supervisors Feature Summary

• Provides reliable system reset via open-drain output when monitored voltage drops below the specified threshold.
• Includes a manual reset input pin allowing for external control of the reset state independent of power conditions.
• Offers a fixed reset delay time to ensure stable operation during power-up sequences.

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify the exact suffix 'ARTRL7' against the manufacturer's official datasheet to confirm tape-and-reel packaging and specific binning. Confirm availability status as distribution channels may list limited stock or end-of-life statuses. Ensure the 4.5V threshold matches the design requirement before ordering.

Supervisors Selection Notes

Select this component when a precise 4.5V threshold is required for single-supervision applications. The open-drain output requires an external pull-up resistor. Consider the 28 ms reset delay for timing constraints. Verify that the SOT-143-4 package fits the PCB layout constraints compared to other available packages in the ADM6315 family.

Supervisors Part Context

This part belongs to the ADM6315 series of open-drain microprocessor supervisory circuits. The series offers various threshold voltages and package options. The '45' indicates the 4.5V trip point, while 'D2' typically denotes specific manufacturing revisions or temperature grades defined by Analog Devices. It serves as a low-cost solution for basic power monitoring tasks.

Supervisors Replacement Considerations

Check for ADM6315 variants with different threshold voltages if the 4.5V setting is flexible. Other manufacturers offer similar open-drain supervisors, but pinouts and electrical characteristics must be verified for direct replacement compatibility.
