MAX6352TZUK+T

Overview

The MAX6352TZUK+T is a dual-supply voltage supervisor from the MAX6351–MAX6360 family, designed to enhance system reliability by monitoring two independent power rails. It features precision factory-set reset thresholds for +2.5V, +3.0V, +3.3V, and +5V inputs. The device operates with a low supply current of 20µA and provides a minimum 100ms power-on reset pulse width. It includes a debounced manual-reset input and ensures RESET validity down to VCC = 1V. Packaged in a compact SOT-23-5 format, it requires no external components for dual-voltage systems.

Feature Summary

• Monitors two independent power-supply voltages with precision factory-set thresholds
• Asserts all reset outputs simultaneously if any monitored supply drops below its threshold
• Maintains valid reset output status as long as either input supply remains above 1.0V
• 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 'Z' against official Analog Devices documentation to confirm exact threshold selections and package variations. Ensure compatibility with the required operating temperature range and voltage levels. Confirm RoHS compliance status through manufacturer certificates. Cross-reference the full part number with authorized distributors to avoid counterfeit components. Validate that the SOT-23-5 footprint matches your PCB design requirements.

Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required within a single IC. It is suitable for designs needing guaranteed reset validity at low supply voltages (down to 1V). Consider the 20µA quiescent current for battery-operated applications. Verify that the fixed factory-set thresholds align with your system's power rail specifications without requiring external resistors.

Part Context

This part belongs to the MAX6351–MAX6360 series of microprocessor supervisory circuits. These devices replace separate ICs or discrete components to improve accuracy and reduce board space. The series offers multiple reset voltage options and small 5- and 6-pin SOT23 packages. They are engineered for high power-supply transient immunity and fully guaranteed performance over temperature.

Replacement Considerations

Direct substitutes include other parts from the MAX6351–MAX6360 family with matching pin counts and similar threshold configurations. Verify functional equivalence regarding reset delay times and manual reset capabilities before substitution.
