MAX6352LTUK

Overview

The MAX6352LTUK 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 with supply currents of 20µA and supports threshold levels including +2.5V, +3.0V, +3.3V, and +5V. It features a debounced manual reset input and is housed in a compact SOT-23 package.

Feature Summary

• Monitors multiple power-supply voltages for system reliability
• Includes a debounced manual-reset input compatible with TTL/CMOS logic
• Provides transient immunity against power-supply fluctuations

Applications

• Personal computer systems monitoring 5V and 3.3V rails
• Intelligent instruments requiring precise voltage supervision
• Portable and battery-powered equipment

Procurement Notes

Verify the specific suffix 'LTUK' against official datasheets to confirm temperature range and package variations. Confirm availability status as distribution channels may list obsolete or limited stock items. Ensure RoHS compliance documentation matches the manufacturing date code for regulatory requirements.

Selection Notes

Select this component for applications requiring simultaneous monitoring of two distinct voltage rails without external resistors. Consider the 20µA supply current for low-power designs. Verify that the factory-set thresholds align with the target system voltages, as adjustable options are not available in this specific part number.

Part Context

This part belongs to the MAX6351–MAX6360 series of microprocessor supervisors designed to improve system accuracy compared to discrete components. These devices assert resets if any monitored supply falls below its threshold, ensuring valid outputs as long as inputs remain above +1.0V.

Replacement Considerations

Compatible substitutes within the same family include MAX6351, MAX6353, and MAX6354. Verify pinout compatibility and threshold voltage specifications before substitution.
