MAX6355UWUT+T

Overview

The MAX6355UWUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors up to three input voltages and provides active low, open-drain reset outputs with a manual reset capability. The device operates within a supply voltage range of up to 5.5 V and features a typical reset delay time of 180 ms. It is housed in a compact SOT-23-6 surface-mount package and is rated for an operating temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple power rails simultaneously for system stability
• Provides manual reset control via dedicated input pin
• Delivers active low open-drain reset signals for logic interfacing

Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Portable electronic device power management

Procurement Notes

Verify component authenticity through authorized channels as the part may be discontinued or subject to supply restrictions. Confirm exact threshold voltages and package variants against the official datasheet before integration. Check for RoHS compliance status and ensure compatibility with existing PCB footprints and design specifications.

Selection Notes

Select this component when simultaneous monitoring of two or three distinct voltage levels is required in space-constrained designs. Ensure the specific threshold voltages match the monitored rails. Consider the SOT-23-6 package size and the active low output polarity for interface compatibility with the target microcontroller or logic family.

Part Context

This part belongs to the MAX6355 series of supervisory circuits designed for universal processor applications. It integrates voltage monitoring and reset generation functions into a single small-footprint IC. The series is characterized by low quiescent current and high accuracy, making it suitable for battery-powered and portable systems requiring reliable power management.

Replacement Considerations

Check for direct pin-compatible substitutes within the MAX635x family. Verify that alternative parts offer identical threshold voltages and reset timing characteristics. Ensure any replacement maintains the same package type and electrical specifications to avoid redesign efforts.
