MAX6355MSUT-T

Overview

The MAX6355MSUT-T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors up to three power supply rails and provides reset signals when voltages fall below specified thresholds. The device operates within a supply voltage range of up to 5.5 V and features an active low, open-drain output type with a manual reset input. It includes a fixed reset delay time of 180 ms and maintains an accuracy of 1.5%. The component is housed in a compact SOT-23-6 surface-mount package and supports operation across a temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple power supply rails simultaneously for system integrity
• Provides manual reset capability via dedicated input pin
• Features active low open-drain output configuration
• Ensures precise voltage supervision with high accuracy

Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Industrial control board reset generation
• Portable electronic device power management

Procurement Notes

Verify the exact suffix and tape/reel specifications against the manufacturer's current datasheet before ordering. Confirm that the component meets all required environmental and safety standards for your specific application. Check for any recent lifecycle status changes or obsolescence notices directly from the manufacturer. Ensure compatibility with your assembly process regarding the SOT-23-6 package. Validate that the threshold voltages match your design requirements precisely.

Selection Notes

Select this component when simultaneous monitoring of multiple voltage rails is required in a small footprint. Consider the fixed 180 ms reset delay and 1.5% accuracy for timing-sensitive applications. Evaluate the need for manual reset functionality versus automatic supervision only. Compare the operating temperature range and supply voltage limits against your system's worst-case conditions. Assess the open-drain output compatibility with your microprocessor's reset input logic levels.
