MAX6352TWUK+T

Overview

The MAX6352TWUK+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides precision monitoring for multiple power-supply voltages, specifically +2.5V, +3.0V, +3.3V, and +5V rails. The device features factory-set reset thresholds and operates with a supply current of 20µA. It includes a watchdog timer with a 46.4-second start-up timeout and a 2.9-second normal timeout. The RESET output remains valid down to VCC = 1.0V. The component is housed in a small 5-pin SOT-23 package.

Feature Summary

• Monitors multiple input supply voltages simultaneously
• Includes a watchdog timer with defined timeout periods
• Features debounced manual-reset input
• Immune to power-supply transients

Applications

• Computers
• Intelligent instruments
• Controllers
• Portable/battery-powered equipment

Procurement Notes

Verify the specific suffix 'TWUK' against official Analog Devices documentation to confirm pinout and threshold configurations. Ensure compatibility with existing board layouts requiring 5-pin SOT-23 packages. Confirm RoHS compliance status through the manufacturer's certification documents before integration into regulated assemblies.

Selection Notes

Select this component when system reliability requires simultaneous monitoring of dual or triple voltage rails without external components. It is suitable for designs needing guaranteed reset validity at low supply voltages. Consider the 20µA supply current for battery-operated applications where power efficiency is critical alongside precise supervision.

Part Context

This part belongs to the MAX6351–MAX6360 series of microprocessor supervisors. These devices are designed to improve system accuracy compared to discrete solutions. They assert reset outputs if any monitored supply drops below its preset threshold. The series supports various fixed thresholds and package options to fit diverse embedded system requirements.

Replacement Considerations

Check for direct substitutes within the MAX6351–MAX6360 family that match the required voltage thresholds and package type. Verify functional equivalence regarding watchdog timeout values and manual reset debounce characteristics before swapping.
