MAX6355LTUT+T

Overview

The MAX6355LTUT+T is a multi-voltage supervisor integrated circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors up to three independent voltage inputs and provides a reset signal when thresholds are exceeded. The device features an active-low, open-drain output and supports manual reset functionality. It operates within a supply voltage range of up to 5.5V and includes a watchdog timer for system reliability. The component is housed in a compact SOT-23-6 surface-mount package and is designed for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Monitors multiple power rails with configurable threshold voltages
• Includes integrated watchdog timer for fault detection
• Supports manual reset input for user-initiated system recovery
• Provides active-low open-drain reset output

Applications

• Microprocessor (MPU) power supply supervision
• Digital system voltage monitoring
• Embedded controller reset management

Procurement Notes

Verify component authenticity through authorized channels as the part status is listed as obsolete. Confirm specific threshold voltage variants against design requirements since suffixes denote different fixed thresholds. Check for RoHS compliance documentation if required for regulatory adherence. Ensure compatibility with existing PCB footprint and soldering profiles for the SOT-23-6 package.

Selection Notes

Select this component when multi-rail supervision with watchdog capability is required in a small form factor. Compare threshold options within the MAX6355 family to match specific rail voltages. Consider the active-low output polarity and open-drain configuration for interface compatibility with downstream logic circuits.
