ADM6315-31D4ARTRL7

Supervisors Overview

The ADM6315-31D4ARTRL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage input and provides an active-low open-drain reset signal. The device features a manual reset function and operates within a supply voltage range of 2.5 V to 5.5 V. It utilizes a SOT-143-4 surface-mount package. Key electrical parameters include a threshold voltage of 3.08 V, a reset delay time of 1.57 s, and a maximum operating temperature of +125 C. The component is designed for reliable system supervision in embedded applications.

Supervisors Feature Summary

• Provides active-low open-drain reset output for monitoring power supply integrity
• Includes manual reset capability for controlled system initialization
• Operates across extended industrial temperature ranges up to +125 C

Supervisors Applications

• Microprocessor power supply supervision
• Embedded system reset circuits
• Industrial control board monitoring

Supervisors Procurement Notes

Verify the specific suffix ARTRL7 against official Analog Devices documentation to confirm tape-and-reel packaging and exact threshold tolerance. Confirm availability status with authorized distributors as supply conditions may vary. Ensure the selected variant matches the required 3.08 V threshold and SOT-143-4 package dimensions for PCB compatibility.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for systems powered between 2.5 V and 5.5 V. The open-drain output allows flexible interfacing with various logic levels. Consider the 1.57 s reset delay for stable power-up sequences. Verify that the manual reset feature aligns with the system's initialization requirements.

Supervisors Part Context

This part belongs to the ADM6315 series of open-drain microprocessor supervisors. It shares the SOT-143-4 form factor with other variants in the family but differs in threshold voltage and output configuration. The series is designed for cost-effective supervision in space-constrained designs requiring reliable reset generation.

Supervisors Replacement Considerations

Direct substitutes include ADM6315-31D3ARTRL7 (push-pull output) or ADM6315-31D1ARTRL7 (active-high output). Cross-reference pinouts and electrical characteristics carefully before substitution.
