MAX6360TWUT

Overview

The MAX6360TWUT is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors multiple power-supply voltages to improve system reliability. The device features precision factory-set reset thresholds for +2.5V, +3.0V, +3.3V, and +5V inputs. It operates with a supply current of 20µA and provides a minimum 100ms power-on reset pulse width. The circuit includes a debounced manual-reset input and a watchdog timer with specified timeout periods. It functions in SOT-23 packages over an extended temperature range.

Feature Summary

• Monitors multiple voltage rails simultaneously to assert reset outputs when any input drops below its preset threshold.
• Includes a watchdog timer input with defined startup and normal timeout periods for system stability.
• Features a debounced manual-reset input compatible with TTL/CMOS logic levels.
• Maintains valid reset output states as long as at least one monitored supply remains above 1.0V.

Applications

• Computers
• Intelligent Instruments
• Controllers
• Multivoltage Systems
• Portable/Battery-Powered Equipment

Procurement Notes

Verify the specific suffix (e.g., TWUT) against the manufacturer's official datasheet to confirm pinout, package type, and electrical characteristics. Ensure compatibility with existing board layouts and voltage requirements before integration. Check current availability status as distribution channels may vary.

Selection Notes

Select this component for designs requiring simultaneous monitoring of two or three distinct voltage rails within a single integrated solution. It is suitable for applications needing precise threshold detection without external components. Consider the low supply current and small package size for space-constrained or battery-operated systems.

Part Context

This part belongs to the MAX6351–MAX6360 series of microprocessor supervisors. These devices are designed to replace separate ICs or discrete components, offering improved accuracy and reliability. The series supports various voltage thresholds and package options, including 5-pin and 6-pin SOT23 configurations.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin replacements within the MAX6360 family. Verify that alternative parts match the required voltage thresholds, package dimensions, and functional features such as watchdog timers and manual reset capabilities.
