MAX6355TWUT-T

Overview

The MAX6355TWUT-T is a triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three independent voltage rails and provides reset signals when thresholds are exceeded. The device operates within a supply voltage range up to 5.5 V and features an active-low, open-drain output. It includes a manual reset input for system control. The component is housed in a compact SOT-23-6 surface-mount package and is rated for operation across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Monitors three distinct voltage inputs simultaneously for system integrity
• Provides active-low open-drain reset signal generation upon fault detection
• Includes manual reset input capability for external system control

Applications

• Microprocessor power supply monitoring in embedded systems
• Triple-rail voltage supervision in industrial control units
• System reset management in portable electronic devices

Procurement Notes

Verify the exact suffix configuration as datasheets often list MAX6355TWUT+T. Confirm availability status as this series may be discontinued or subject to supply constraints. Ensure the specific threshold voltages match your design requirements before ordering. Check RoHS compliance documentation for regulatory adherence.

Selection Notes

Select this component when simultaneous monitoring of three voltage lines is required in a minimal footprint. The SOT-23-6 package suits space-constrained designs. Verify that the fixed threshold voltages align with the target supply rails. Consider the open-drain output compatibility with the downstream logic levels.

Part Context

This part belongs to the MAX6355 family of dual/triple-voltage supervisory circuits. These devices are designed to ensure reliable system startup and shutdown sequences. The TWUT variant specifically denotes the triple-monitor configuration with defined threshold characteristics suitable for standard logic families.
