MAX6351LTUT+T

Overview

The MAX6351LTUT+T is a dual-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 2.0 V to 5.5 V and monitors two independent input voltages with threshold levels of 3.08 V and 4.63 V. The device features an active-low, push-pull reset output and includes a manual reset input for system control. It incorporates a watchdog timer with a fixed timeout period of 100 ms minimum. The component is housed in a surface-mount SOT-23-6 package and is rated for operation between -40°C and +85°C.

Feature Summary

• Dual-channel voltage monitoring with specified threshold levels for critical power rails
• Integrated watchdog timer with manual reset capability for enhanced system reliability
• Active-low push-pull reset output providing robust drive capability
• Compact SOT-23-6 surface-mount packaging for space-constrained designs

Applications

• Microprocessor and microcontroller power supply supervision
• Embedded systems requiring dual-voltage monitoring
• Industrial control units with watchdog protection needs
• Portable electronic devices utilizing low-voltage logic

Procurement Notes

Verify the specific suffix LTUT against the manufacturer's current part numbering guide to ensure correct threshold and package configuration. Confirm RoHS compliance status through official documentation. Check for obsolescence notices or lifecycle changes directly from Analog Devices. Validate pinout compatibility if replacing existing components in established designs.

Selection Notes

Select this component when dual independent voltage monitoring is required alongside integrated watchdog functionality. Ensure the monitored rail voltages align with the fixed thresholds of 3.08 V and 4.63 V. Consider the push-pull output requirement versus open-drain alternatives based on downstream interface needs. Verify that the operating temperature range meets the environmental conditions of the target application.
