MAX6352SVUK

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 active-low reset outputs when any input drops below its preset threshold. The device operates with a supply voltage range up to 5.5V and features a manual reset input. It consumes only 20µA of supply current and includes a debounced manual reset function. The component is housed in a compact SOT-23-5 package and is designed for extended industrial temperature operation from -40°C to +85°C.

Feature Summary

• Dual-input monitoring capability for independent power rails
• Active-low open-drain reset outputs with debounced manual reset input
• Ultra-low 20µA supply current consumption for portable applications
• Compact 5-pin SOT-23 surface-mount packaging

Applications

• Portable and battery-powered equipment
• Multivoltage system supervision
• Controllers and intelligent instruments
• Personal computer systems

Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact threshold voltages and package variations. Confirm RoHS compliance status and lead-free designation as required by project specifications. Check current availability status as distribution channels may vary. Ensure the ordering part number matches the required electrical parameters before procurement.

Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required within a limited board space. The low quiescent current makes it suitable for battery-operated designs where power efficiency is critical. Verify that the factory-set threshold voltages align with the target supply rails. Consider the open-drain output configuration for compatibility with the downstream logic family voltage levels.

Part Context

This part belongs to the MAX6351–MAX6360 series of microprocessor supervisors. These devices are engineered to improve system reliability by replacing discrete components with integrated solutions. The series offers multiple reset voltage options and is available in small packages to support space-constrained designs across various industrial and consumer electronics applications.

Replacement Considerations

Cross-reference with other MAX635x variants such as MAX6351 or MAX6353 if single or triple voltage monitoring is needed. Verify pinout compatibility when substituting with similar dual-supervisor ICs from other manufacturers. Ensure equivalent threshold accuracy and reset delay characteristics match the original design requirements.
