MAX6346XR34-T

Overview

The MAX6346XR34-T is a single-channel microprocessor reset supervisor circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors a single voltage supply and asserts an active-low reset signal when the monitored voltage falls below a precise threshold of 3.4V. The device features a push-pull, totem-pole output structure and provides a minimum reset timeout period of 100ms to ensure system stability during power-up or brown-out events. Designed for robust operation in demanding environments, it functions within an extended industrial temperature range from -40°C to +85°C. The component is housed in a compact SC-70-3 surface-mount package, facilitating efficient space utilization in portable and embedded electronic designs requiring reliable power management supervision.

Feature Summary

• Monitors a single voltage rail with a fixed 3.4V threshold
• Generates an active-low reset signal via push-pull output
• Ensures system stability with a minimum 100ms reset timeout

Applications

• Microprocessor and microcontroller power supply supervision
• Embedded systems requiring brown-out protection
• Portable electronic devices with limited board space

Procurement Notes

Verify the manufacturer part number MAX6346XR34-T against official Analog Devices documentation to confirm authenticity. Ensure the received components match the specified SC-70-3 package and electrical characteristics. Cross-reference datasheets for any specific handling requirements or environmental certifications associated with this product line.

Selection Notes

Select this component when a fixed 3.4V monitoring threshold is required for a single voltage rail. It is suitable for applications needing an active-low reset output with a guaranteed minimum timeout duration. Consider the SC-70-3 package size for space-constrained designs operating within the specified industrial temperature range.

Part Context

This component belongs to the MAX6346 series of simple reset circuits designed for monitoring voltage levels in digital systems. The series offers various threshold voltages and package options to accommodate different design requirements. As a member of the Maxim Integrated portfolio now under Analog Devices, it maintains compatibility with established power management solutions.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternative part numbers. Ensure any replacement matches the SC-70-3 package, 3.4V threshold, and active-low output polarity.
