MAX6360TZUT

Overview

The MAX6360TZUT is a dual/triple-voltage microprocessor supervisory circuit in a 6-pin SOT-23 package. It monitors multiple power supplies with precision factory-set thresholds, consuming only 20µA supply current. The device features a debounced manual-reset input and a watchdog timer with a 46.4-second start-up timeout and 2.9-second normal timeout. It guarantees reset validity down to VCC5 = 1V or VCC3 = 1V and includes power-supply transient immunity without requiring external components for dual-voltage systems.

Feature Summary

• Precision monitoring of multiple +2.5V, +3.0V, +3.3V, and +5V power-supply voltages
• Watchdog timer with specified start-up and normal timeouts
• Debounced TTL/CMOS-compatible manual-reset input
• Guaranteed RESET valid at low supply voltages

Applications

• Computers
• Intelligent Instruments
• Controllers
• Multivoltage Systems
• Portable/Battery-Powered Equipment

Procurement Notes

Verify the exact suffix (e.g., TZUT vs LTUT) against the manufacturer's official datasheet to confirm threshold voltages and timeout specifications. Ensure the component matches the required voltage monitoring channels and package type. Cross-reference the ordering information with Analog Devices documentation to avoid confusion between similar part numbers within the MAX6360 family.

Selection Notes

Select this component when precise supervision of multiple voltage rails is required in space-constrained designs. The integrated watchdog and manual reset simplify system design by eliminating external components. Consider the specific factory-set thresholds and timeout values to ensure compatibility with the target microprocessor's timing requirements and voltage levels.

Part Context

The MAX6360 series improves system reliability compared to discrete solutions. It significantly enhances accuracy by monitoring multiple supply voltages simultaneously. The device asserts reset outputs if any input drops below its preset threshold. This integration reduces board space and cost while maintaining high performance in complex multivoltage environments.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the available documentation. Verify compatibility with alternative devices from the same family based on specific electrical parameters and pinout configurations.
