MAX6351LRUT+T

Overview

The MAX6351LRUT+T is a dual voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors two independent supply voltages with fixed thresholds of 2.63V and 4.63V. The device features an active-low, open-drain reset output and includes a manual reset input for system control. It incorporates a watchdog timer to enhance reliability and operates within a temperature range of -40°C to +85°C. The component is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Dual-channel voltage supervision with fixed threshold monitoring capabilities
• Integrated watchdog timer functionality for system reliability enhancement
• Manual reset input allowing external control over the reset state

Applications

• Embedded systems requiring dual power rail monitoring
• Microprocessor-based designs needing reliable reset generation
• Industrial equipment utilizing watchdog protection mechanisms

Procurement Notes

Verify current availability status as this component may be subject to discontinuation or limited supply constraints. Confirm that the specific suffix corresponds to the required pinout and electrical characteristics. Ensure compatibility with existing board layouts due to the SOT-23-6 package dimensions. Check for RoHS compliance documentation if required for your region. Validate that the fixed threshold voltages meet your design specifications before procurement.

Selection Notes

Select this part when dual voltage monitoring is required with fixed thresholds. The open-drain output allows for flexible logic level interfacing. Consider the manual reset feature if external reset control is necessary. Verify that the operating temperature range suits your environment. Compare against other MAX6351 variants if different threshold voltages are needed.

Part Context

This component belongs to the MAX6351 family of dual/triple-voltage microprocessor supervisory circuits. It shares functional similarities with other parts in the series but differs in specific threshold voltages and package options. The LRUT+T designation indicates specific threshold values and tape-and-reel packaging. It is designed for applications requiring robust power management and reset sequencing.

Replacement Considerations

Check for direct substitutes within the MAX6351 family with compatible thresholds. Verify pin-to-pin compatibility with alternative packages if space constraints change. Ensure equivalent watchdog and manual reset features are present in any replacement part.
