ADM6315-44D4ARTRL7

Supervisors Overview

The ADM6315-44D4ARTRL7 is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage input and provides an open-drain reset output. The device features a manual reset function 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 SOT-143-4 surface-mount package. Key electrical parameters include a reset delay time of 1.57 seconds and a threshold voltage corresponding to the '44' suffix designation. The component is designed for reliable system supervision without an integrated watchdog timer or battery backup switch.

Supervisors Feature Summary

• Provides open-drain reset signal generation for monitored power rails
• Includes manual reset capability for system control flexibility
• Operates in a compact four-lead SOT-143 surface-mount package

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific threshold voltage associated with the D4 suffix against the official Analog Devices datasheet before integration. Confirm package pinout compatibility with the target PCB footprint. Ensure the operating temperature range meets the application requirements. Check current availability status as distribution may vary. Validate that the open-drain output configuration aligns with the downstream logic interface requirements.

Supervisors Selection Notes

Select this component when a simple, low-pin-count supervisor is required for single-rail monitoring. The open-drain output allows for wired-OR configurations or level shifting. Consider the 1.57-second reset delay for timing-sensitive applications. The absence of a watchdog timer simplifies design if external timing is preferred. Verify the threshold voltage matches the specific rail being monitored.

Supervisors Part Context

This part belongs to the ADM6315 family of supervisory circuits from Analog Devices. The family offers various threshold voltages and output types. The ADM6315 series is characterized by its small SOT-143-4 form factor and basic supervision functions. It serves as a fundamental building block for ensuring stable operation in digital systems by detecting under-voltage conditions.

Supervisors Replacement Considerations

Check for other ADM6315 variants with different threshold suffixes if the voltage level differs. Compare with MAX6315 equivalents for potential pin-compatible alternatives. Verify functional equivalence regarding reset delay and output type before substitution.
