ADM6315-44D4ARTZRL

Supervisors Overview

The ADM6315-44D4ARTZRL is an open-drain microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage input and provides a reset signal when the supply voltage drops below a specific threshold. The device features a manual reset capability and operates within a supply voltage range of 2.5 V to 5 V, with a maximum rating of 5.5 V. It utilizes a 4-lead SOT-143 surface-mount package. The reset delay time for this variant is specified as 1.57 seconds. The output configuration supports open-drain operation.

Supervisors Feature Summary

• Provides open-drain reset output for microprocessor supervision
• Includes manual reset functionality for system control
• Monitors a single voltage input channel
• Operates within standard low-voltage ranges up to 5.5 V

Supervisors Applications

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

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions align with semiconductor handling guidelines to prevent moisture sensitivity damage. Validate part marking against official datasheet specifications to avoid counterfeit substitution risks during procurement.

Supervisors Selection Notes

Select this component when an open-drain reset output is required for interfacing with logic circuits. The fixed threshold voltage determines the trip point; ensure it matches the monitored rail's minimum operating level. Consider the 1.57-second reset delay for timing requirements. Verify that the SOT-143 package fits the PCB layout constraints and thermal requirements of the application design.

Supervisors Part Context

This part belongs to the ADM6315 series of supervisory circuits from Analog Devices. The series offers various threshold voltages and reset delays to accommodate different system requirements. The suffix indicates specific threshold and delay characteristics. These devices are designed for reliable voltage monitoring in compact form factors suitable for modern electronics.

Supervisors Replacement Considerations

Check for exact threshold voltage match (4.4 V implied by model) and identical reset delay (1.57 s). Verify pinout compatibility with SOT-143-4 packages. Ensure output type (open-drain) matches existing circuit design. Consult Analog Devices documentation for qualified alternatives within the same family.
