MAX6352TYUK

Overview

The MAX6352TYUK+ 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 voltage thresholds including +2.5V, +3.0V, +3.3V, and +5V. It features a debounced manual reset input and is available in compact SOT-23 packages.

Feature Summary

• Monitors multiple power-supply voltages to improve system reliability
• Provides precision factory-set power-supply reset thresholds
• Includes a debounced TTL/CMOS-compatible manual-reset input

Applications

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

Procurement Notes

Verify the specific suffix 'TY' against official Maxim Integrated documentation to confirm exact threshold voltages and package variations. Confirm RoHS compliance status and current lifecycle stage, as older Maxim parts may be discontinued or subject to obsolescence notices. Ensure the component matches the required operating temperature range for the intended application environment.

Selection Notes

Select this component for applications requiring simultaneous monitoring of two distinct voltage rails without external components. Consider the 20µA supply current for battery-operated designs. Verify that the fixed threshold levels align with the target power supply voltages, as adjustable alternatives exist within the MAX63xx family if precise custom thresholds are needed.

Part Context

The MAX6352 belongs to the MAX6351–MAX6360 series of microprocessor supervisors designed to replace discrete monitoring solutions. These devices integrate multiple reset functions into small SOT-23 packages, reducing board space and improving accuracy compared to separate ICs. The series is optimized for multivoltage systems common in portable and industrial electronics.

Replacement Considerations

Compatible substitutes include other members of the MAX635x series such as MAX6351, MAX6353, or MAX6354, depending on the required number of monitored inputs and output configurations. Verify pinout compatibility and threshold voltage specifications before substitution.
