MAX6351LRUT+

Overview

The MAX6351LRUT+ is a dual-channel voltage supervisor manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent supply voltages and asserts an active-low reset signal when inputs fall below specified thresholds. The device features a manual reset input, allowing for system initialization control. It operates within a supply voltage range of 1.2V to 5.5V and includes a watchdog timer function to enhance system reliability. The component is housed in a compact SOT-23-6 surface-mount package and supports operation across an extended industrial temperature range.

Feature Summary

• Dual-channel voltage monitoring with configurable threshold detection
• Manual reset input for controlled system initialization
• Integrated watchdog timer for fault recovery
• Active-low open-drain reset output

Applications

• Portable electronic devices requiring multi-voltage supervision
• Industrial control systems needing watchdog protection
• Embedded microcontroller power management circuits
• Battery-operated equipment with low-power requirements

Procurement Notes

Verify the specific suffix 'L' indicates the correct threshold voltage combination for your application design. Confirm that the SOT-23-6 package dimensions match your PCB footprint constraints. Check current availability status as this component may be subject to limited supply or end-of-life notices from the manufacturer. Ensure compatibility with your system's operating temperature range specifications before finalizing procurement decisions.

Selection Notes

Select this part when dual-supervision is required in space-constrained designs. The manual reset feature provides flexibility for complex startup sequences. Consider the watchdog timer capability if system stability against software hangs is critical. Verify that the threshold voltages align precisely with your monitored rails to prevent nuisance resets. Evaluate the low quiescent current benefit for battery-powered applications where efficiency is paramount.

Part Context

This component belongs to the MAX6351 series of voltage supervisors designed for portable and industrial applications. It shares functional similarities with other Maxim Integrated supervisory ICs but offers specific threshold combinations and packaging options. The series is known for integrating watchdog functionality alongside standard voltage monitoring capabilities in small form factors suitable for modern electronics.
