MAX6352SVUK-T

Overview

The MAX6352SVUK-T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent power supplies, asserting reset outputs when voltages drop below preset thresholds. The device operates within a supply voltage range of 1.0V to 5.5V and features a low supply current of 20µA. It includes a debounced manual reset input and offers a watchdog timer with specific timeout periods. The component is housed in a compact SOT-23-5 package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple power-supply voltages with precision factory-set thresholds
• Includes a watchdog timer with startup and normal timeout capabilities
• Features a debounced manual-reset input compatible with TTL/CMOS logic

Applications

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

Procurement Notes

Verify the exact suffix configuration against the manufacturer's official datasheet to ensure correct threshold voltage selection and package type. Confirm RoHS compliance status and lead-free specifications prior to ordering. Check for obsolescence notices or lifecycle changes directly from Analog Devices documentation. Ensure the selected variant matches the required voltage monitoring parameters for the target application design.

Selection Notes

Select this component for designs requiring simultaneous monitoring of two distinct power rails without external components. Consider the 20µA quiescent current for battery-operated applications. Verify that the available factory-set thresholds align with the system's critical voltage levels. Evaluate the need for the integrated watchdog timer functionality versus discrete solutions based on board space constraints.

Part Context

This part belongs to the MAX6351–MAX6360 family of microprocessor supervisors designed to improve system reliability. These devices replace separate ICs or discrete components by integrating multiple reset functions into a single small package. The series is characterized by guaranteed operation over temperature and transient immunity, making them suitable for robust industrial and consumer electronics applications.

Replacement Considerations

Consult the official MAX6352 datasheet for confirmed substitute part numbers within the same product family. Verify pinout compatibility and electrical parameter equivalence before substitution.
