MAX6352LTUK+

Overview

The MAX6352LTUK+ 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 and accuracy. The device features precision factory-set reset thresholds for +2.5V, +3.0V, +3.3V, and +5V supplies. It operates with a supply current of 20µA and includes a debounced manual-reset input. The component is available in small 5- and 6-pin SOT23 packages and functions over an extended temperature range.

Feature Summary

• Monitors multiple power-supply voltages with precision factory-set thresholds
• Asserts reset outputs if any monitored supply drops below its preset threshold
• Includes a debounced TTL/CMOS-compatible manual-reset input
• Offers watchdog timer functionality with specified startup and normal timeout periods

Applications

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

Procurement Notes

Verify the specific suffix 'L' against official Maxim Integrated documentation to confirm voltage threshold options and package availability. Confirm RoHS compliance status through the manufacturer's datasheet or certification documents. Ensure the ordering information matches the required pin configuration and thermal characteristics for the target application environment.

Selection Notes

Select this component when monitoring two or three distinct voltage rails is required within a compact footprint. The fixed thresholds simplify design compared to programmable alternatives. Consider the 20µA supply current for battery-operated applications. Verify that the SOT23 package size meets the board space constraints and that the operating temperature range aligns with the environmental conditions.

Part Context

This part belongs to the MAX6351–MAX6360 series of microprocessor supervisors. These devices are designed to replace separate ICs or discrete components for improved system reliability. The series offers various reset voltages and package options, including 5-pin and 6-pin SOT23 configurations. They are engineered to ignore fast transients on monitored supplies while ensuring valid reset signals down to low supply voltages.

Replacement Considerations

Check for MAX6352 variants with different suffixes (e.g., MS, ESA) for alternative package types like SOIC. Verify functional compatibility regarding threshold voltages and output drive capabilities before substitution.
