ADM6315-44D4ARTZR7

Supervisors Overview

The ADM6315-44D4ARTZR7 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 a fixed reset threshold voltage of 4.39 V. The device utilizes an SOT-143-4 surface-mount package and provides an open-drain output. It includes a debounced manual reset input and offers a reset timeout period of 1.12 seconds. The component supports operation across an extended temperature range from -40°C to +125°C, ensuring reliability in demanding environments.

Supervisors Feature Summary

• Monitors power supply voltages with a factory-set threshold for precise supervision
• Integrates a debounced manual reset input to prevent false triggering
• Provides robust supervision suitable for safety-critical applications

Supervisors Applications

• Safety-critical automotive applications
• General voltage monitoring systems
• Embedded systems requiring reliable power supervision

Supervisors Procurement Notes

Verify the specific suffix ARTZR7 confirms the tape-and-reel packaging format and ensure compatibility with automated assembly processes. Confirm that the fixed 4.39 V threshold aligns with the target system's voltage requirements. Check current availability status as distribution may vary. Ensure the SOT-143-4 footprint matches the design layout constraints.

Supervisors Selection Notes

Select this component when a fixed high-voltage threshold near 4.4 V is required for 5 V systems. The open-drain output allows for flexible interfacing with various logic levels. Consider the 1.12 s timeout if longer initialization periods are needed. Verify that the manual reset feature meets system safety protocols. The wide operating temperature range supports industrial and automotive use cases.

Supervisors Part Context

This part belongs to the ADM6315 family of voltage supervisors from Analog Devices. The series offers multiple threshold options ranging from 1.1 V to 5 V in increments. The ADM6315-44D4ARTZR7 specifically targets applications needing supervision around the 4.4 V level. It shares common features like low quiescent current and compact packaging with other variants in the lineup.

Supervisors Replacement Considerations

Cross-reference with MAX6315US31D3+T for similar functionality, noting differences in threshold voltage (3.08 V vs 4.39 V) and reset timeout (200 ms vs 1.12 s). Verify pinout compatibility between SOT-143-4 packages before substitution.
