MAX6355LSUT+T

Overview

The MAX6355LSUT+T is a dual/three-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three voltage inputs with threshold voltages of 2.93 V and 4.63 V, and overvoltage thresholds of 2.98 V and 4.72 V. The device features an active low, open-drain output type and includes a manual reset input but lacks a watchdog timer or battery backup switch. It operates within a supply voltage range up to 5.5 V, consumes 20 uA of working power current, and maintains an accuracy of 1.5%. The reset delay time is 180 ms, and it functions reliably across a temperature range from -40 C to +85 C in an SOT-23-6 package.

Feature Summary

• Monitors multiple voltage rails simultaneously for system integrity
• Provides manual reset capability for user-initiated control
• Delivers active low open-drain output signals

Applications

• Multi-rail power supply monitoring in embedded systems
• Microprocessor reset generation in industrial controllers
• Voltage supervision in portable electronic devices

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm RoHS compliance details and specific lot traceability requirements before procurement. Check for obsolescence notices or lifecycle changes as the product may be subject to discontinuation. Ensure packaging specifications match design integration needs.

Selection Notes

Select this component when simultaneous monitoring of three distinct voltage levels is required without watchdog functionality. Consider the 1.5% accuracy and 180 ms reset delay for timing-sensitive applications. Evaluate the SOT-23-6 footprint against board space constraints. Compare against variants with different threshold voltages if standard values do not match target rails.

Part Context

This part belongs to the MAX6355L series of supervisory circuits designed for multi-voltage monitoring. It shares architectural similarities with other MAX635x family members but offers specific threshold configurations. The series targets applications requiring reliable power management without complex interface protocols. It complements broader power management solutions by providing dedicated hardware supervision.
