MAX6360SYUT

Overview

The MAX6360SYUT is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It provides precision monitoring for multiple power-supply voltages, including +2.5V, +3.0V, +3.3V, and +5V options. The device features factory-set reset thresholds with a typical accuracy of ±1%. It operates within an input voltage range of +1.0V to +5.5V and consumes a maximum supply current of 20µA. The component includes a debounced manual-reset input and offers a watchdog timer with a 46.4-second startup timeout and a 2.9-second normal timeout. It is available in a small 6-pin SOT-23 package.

Feature Summary

• Precision monitoring of multiple power-supply voltages with factory-set thresholds
• Integrated watchdog timer with extended startup and normal timeout periods
• Debounced manual-reset input compatible with TTL/CMOS logic levels
• Low-power operation with minimal supply current consumption

Applications

• Computers and intelligent instruments requiring multi-rail supervision
• Controllers and embedded systems needing reliable power management
• Portable and battery-powered equipment prioritizing low standby current
• Multivoltage systems ensuring synchronized reset assertions across rails

Procurement Notes

Verify the specific suffix (SY) against official Analog Devices documentation to confirm the exact voltage threshold configuration and temperature grade. Ensure the ordering part number matches the required pinout and package type. Confirm availability status through authorized distributors as supply conditions may vary. Cross-reference the datasheet revision to ensure compatibility with design requirements.

Selection Notes

Select this component when designing systems that require simultaneous supervision of two or three distinct voltage rails. It is suitable for applications demanding high accuracy without external resistor networks. Consider the SOT-23 package size constraints and the need for integrated watchdog functionality. Evaluate the 20µA supply current against total system power budgets for battery-operated designs.

Part Context
