MAX6360LSUT

Overview

The MAX6360LSUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors multiple power-supply voltages, including +2.5V, +3.0V, +3.3V, and +5V rails. The device features precision factory-set reset thresholds with 1.5% accuracy. It operates within an extended temperature range of -40°C to +85°C and draws a typical supply current of 20µA. Key electrical parameters include a maximum supply voltage of 5.5V, a minimum power-on reset pulse width of 100ms, and watchdog timer timeouts of 46.4s startup and 2.9s normal operation.

Feature Summary

• Monitors multiple power-supply voltages simultaneously to improve system reliability
• Includes a watchdog timer with specified startup and normal timeout periods
• Features a debounced manual-reset input compatible with TTL/CMOS logic

Applications

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

Procurement Notes

Verify the specific suffix against official datasheets to confirm threshold levels and package type. Confirm RoHS compliance status for the specific revision. Check manufacturer lifecycle status as availability may be limited or subject to factory special orders. Ensure the active-low output configuration matches the design requirements.

Selection Notes

Select this component when monitoring two or three distinct voltage rails is required in a compact footprint. The low supply current makes it suitable for battery-operated applications. Verify that the preset threshold levels align with the target power supplies. Consider the watchdog functionality if system stability requires automatic recovery from software hangs.

Part Context

This part belongs to the MAX6351–MAX6360 series of microprocessor supervisors. These devices are designed to replace separate ICs or discrete components, offering improved accuracy and system reliability. The series utilizes small 5- and 6-pin SOT23 packages to minimize board space while providing essential power management functions for embedded systems.

Replacement Considerations

Check for MAX6358LSUT+T or MAX6359LSUT+T for similar dual/three-voltage supervision with comparable pinouts and features. Verify functional equivalence regarding threshold voltages and watchdog timing before substitution.
