MAX6360MSUT+

Overview

The MAX6360MSUT+ is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors multiple power-supply voltages to improve system reliability. The device operates with a supply voltage range of +2.5V to +5.5V and consumes only 20µA of supply current. It features precision factory-set reset thresholds for +2.5V, +3.0V, +3.3V, and +5V inputs. The circuit provides a debounced manual-reset input and includes a watchdog timer with a 46.4-second start-up timeout and a 2.9-second normal timeout. It is housed in a small 6-pin SOT-23 package.

Feature Summary

• Monitors multiple power-supply voltages including +2.5V, +3.0V, +3.3V, and +5V rails
• Includes a debounced TTL/CMOS-compatible manual-reset input
• Integrates a watchdog timer with specified start-up and normal timeouts
• Operates with low supply current consumption

Applications

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

Procurement Notes

Verify the specific suffix configuration against the official datasheet to ensure correct threshold selection and package type. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Check for obsolescence or limited availability status through authorized distributors before finalizing procurement plans.

Selection Notes

Select this component when monitoring two or three distinct voltage rails is required within a single IC footprint. Ensure the available factory-set thresholds match the target power supplies. Consider the 20µA quiescent current suitability for battery-operated designs. Verify that the SOT-23-6 package dimensions fit the board layout constraints.

Part Context

This part belongs to the MAX6351–MAX6360 family of microprocessor supervisors designed to replace discrete components. These circuits simplify design by integrating multiple voltage monitors into a compact package. The series emphasizes accuracy and reliability for embedded systems requiring precise power management supervision.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX63xx series. Verify if newer revisions offer improved thermal performance or updated packaging options. Ensure substitute parts maintain the same watchdog timer functionality and reset threshold precision.
