MAX6352TWUK

Overview

The MAX6352TWUK+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides precision monitoring for multiple power-supply voltages, including +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 debounced manual-reset input and a watchdog timer with a 46.4s startup timeout. The component is available in small 5- and 6-pin SOT-23 packages and functions over an extended temperature range.

Feature Summary

• Precision monitoring of multiple voltage rails with factory-set thresholds
• Integrated watchdog timer with specified startup and normal timeouts
• Debounced TTL/CMOS-compatible manual-reset input
• Low supply current consumption for battery-powered applications

Applications

• Multivoltage computer systems
• Intelligent instruments and controllers
• Portable and battery-powered equipment

Procurement Notes

Verify the exact suffix (e.g., +T) against the manufacturer's current datasheet to ensure pinout and package compatibility. Confirm availability status as distribution channels may list limited stock or obsolete status. Cross-reference the specific voltage threshold options required for your design, as the base part number covers a family of variants with different preset levels.

Selection Notes

Select this component when system reliability requires simultaneous monitoring of two or three distinct power supplies without external discrete components. Ensure the application demands low quiescent current and fits within the SOT-23 footprint constraints. Verify that the required reset thresholds match the available factory-set options for the specific voltage rails in use.

Part Context

This part belongs to the MAX6351–MAX6360 series of microprocessor supervisors designed to improve system accuracy compared to discrete solutions. These devices assert reset outputs if any monitored supply drops below its threshold. The series offers various configurations, including dual or triple voltage monitoring, watchdog timers, and manual reset inputs, all housed in compact surface-mount packages.

Replacement Considerations

Compatible substitutes include other parts from the MAX6351–MAX6360 family, such as the MAX6356 or MAX6359, depending on whether dual or triple voltage monitoring is needed. Ensure the replacement matches the required voltage thresholds and package type.
