MXD1817XR29+

Supervisors Overview

The MXD1817XR29+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a reset circuit designed to monitor system voltage levels and generate a reset signal when the supply drops below a specific threshold. The component is housed in a 3-pin uPak package, suitable for surface-mount applications. This device ensures reliable operation by providing a stable reset output to connected logic or microcontrollers during power-up and brown-out conditions.

Supervisors Feature Summary

• Provides automated system reset upon detection of undervoltage events
• Utilizes a compact 3-pin uPak surface-mount package for space-constrained designs
• Integrates internal hysteresis to prevent false triggering during noise transients

Supervisors Applications

• Embedded system power supervision
• Microcontroller reset generation
• Portable electronic device power management

Supervisors Procurement Notes

Verify current availability status directly with authorized distributors, as this part number may be subject to limited supply or discontinuation. Confirm that the 3-pin uPak package matches your PCB footprint requirements. Ensure the selected variant aligns with the required reset threshold voltage for your specific application design.

Supervisors Selection Notes

Select this component when a low-cost, single-channel voltage supervisor is required for basic power monitoring. Consider the fixed reset threshold inherent to the XR29 suffix against other variants in the MXD1817 family if different trip points are needed. Evaluate the thermal performance and physical size constraints of the uPak package relative to your enclosure design.

Supervisors Part Context

The MXD1817 series represents a line of low-power supervisory circuits from Maxim Integrated. These devices are engineered to provide robust protection for digital systems by monitoring supply rails. The MXD1817XR29+ specifically denotes a version within this family characterized by its particular reset threshold and packaging configuration, serving as a fundamental building block for power integrity in mixed-signal environments.
