MAX6355TYUT

Overview

The MAX6355TYUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of up to 5.5 V and features an active low, open-drain output type with manual reset capability. The device monitors three inputs with threshold voltages of 2.63 V and 4.38 V, and overvoltage thresholds of 2.68 V and 4.46 V. It includes a fixed reset delay time of 180 ms and maintains an accuracy of 1.5%. The component functions at a working supply current of 20 uA and dissipates power up to 695 mW. It is housed in an SOT-23-6 package and supports surface mount installation across an operating temperature range from -40 C to +85 C.

Feature Summary

• Provides simultaneous supervision for multiple voltage rails using dual or triple input monitoring channels.
• Integrates a manual reset input allowing external control over the system reset state.
• Delivers precise voltage monitoring with specified accuracy and defined reset delay times.

Applications

• Microprocessor power supply monitoring
• Portable equipment voltage supervision
• Battery-powered system protection

Procurement Notes

Verify the exact suffix configuration against official datasheets as variations exist within the MAX6355 family. Confirm availability status directly with authorized distributors since specific variants may be discontinued or subject to limited supply. Ensure the selected part matches the required threshold voltages and package type for your design.

Selection Notes

Select this component when designing systems requiring supervision of two or three distinct voltage levels. Consider the specific threshold requirements and the necessity for manual reset functionality. Verify that the SOT-23-6 package fits your board layout constraints and that the operating temperature range meets your environmental specifications.

Part Context

This part belongs to the MAX6355M series of dual/triple-voltage microprocessor supervisory circuits. It is designed to monitor power supplies in portable and battery-operated applications. The series offers various threshold options and package configurations to suit different system requirements while maintaining low power consumption.

Replacement Considerations

Check for direct substitutes within the MAX6355 family such as MAX6355MRUT+T or other variants with compatible thresholds. Verify pin compatibility and electrical characteristics before substitution.
