MAX6382XR46D3+T

Supervisors Overview

The MAX6382XR46D3+T is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1.8V to 5V and features a fixed reset threshold voltage of 4.63V. The device provides an active-high, push-pull reset output with a manual reset input capability. It utilizes a UDFN-6 surface-mount package and offers a reset delay time of 2.24 seconds. The component supports an operating temperature range from -40°C to +125°C and consumes low supply current.

Supervisors Feature Summary

• Monitors power-supply voltages from 1.8V to 5.0V with a factory-set threshold of 4.63V
• Provides an active-high, push-pull reset output for reliable signal interfacing
• Includes a manual reset input pin allowing external assertion of the reset state
• Operates across an extended industrial temperature range of -40°C to +125°C

Supervisors Applications

• Microprocessor system power supervision
• Portable battery-powered equipment monitoring
• Consumer electronics voltage tracking
• Industrial control board power integrity verification

Supervisors Procurement Notes

Verify the specific suffix D3+T against the manufacturer's official datasheet to confirm the exact threshold voltage and package variant. Confirm RoHS compliance status and lead-free certification requirements prior to ordering. Ensure the sourcing channel provides valid traceability documentation for this discontinued or limited-stock component series.

Supervisors Selection Notes

Select this part when a fixed 4.63V threshold is required for systems powered between 1.8V and 5V. The active-high push-pull output simplifies interface design compared to open-drain alternatives. Consider the UDFN-6 package for space-constrained PCB layouts requiring robust thermal performance in high-temperature environments.

Supervisors Part Context

This component belongs to the MAX6381–MAX6390 family of microprocessor supervisory circuits designed for low-voltage applications. The family offers various threshold options and output configurations to accommodate different system architectures. The MAX6382 variant specifically provides an active-high output, distinguishing it from other family members that may offer active-low signals.

Supervisors Replacement Considerations

Check for direct cross-references within the MAX6382LT series or compatible Maxim Integrated voltage supervisors. Verify that any substitute maintains the 4.63V threshold, active-high push-pull output, and UDFN-6 footprint compatibility.
