MAX6355TZUT+T

Overview

The MAX6355TZUT+T is a triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three independent voltage rails within a compact SOT-23-6 surface-mount package. The device features active-low open-drain reset outputs with a fixed 180 ms reset delay time to ensure stable power-up sequencing. It operates over an extended temperature range of -40°C to +85°C and supports a maximum supply voltage of 5.5 V. Key electrical specifications include a quiescent current of 20 µA, threshold voltages of 2.32 V and 3.08 V for two channels, and an accuracy of 1.5%.

Feature Summary

• Monitors three distinct voltage inputs simultaneously for comprehensive system supervision.
• Provides manual reset capability allowing external control over the reset state.
• Delivers active-low open-drain reset signals compatible with standard logic interfaces.

Applications

• Embedded systems requiring multi-rail power monitoring
• Industrial control units needing reliable voltage supervision
• Communication equipment ensuring stable power delivery

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific manufacturing date codes relevant to project requirements. Ensure the SOT-23-6 package matches PCB footprint designs. Review datasheet revisions for any functional updates before finalizing procurement decisions.

Selection Notes

Select this component when triple-voltage monitoring is required in space-constrained designs. The SOT-23-6 package offers a small footprint suitable for dense layouts. Consider the 180 ms reset delay and open-drain output configuration for compatibility with downstream logic circuits. Verify that the specified threshold voltages align with the monitored rail levels.

Part Context

This part belongs to the MAX6355T series of uP supervisors from Maxim Integrated. These devices are designed for low-power applications requiring precise voltage monitoring. The series typically includes variants with different threshold combinations and package options to suit various embedded system architectures.

Replacement Considerations

Check for MAX6355 variants with identical pinouts and electrical characteristics. Verify that substitute parts maintain the same SOT-23-6 package and active-low open-drain output type. Ensure replacement components meet the -40°C to +85°C operating temperature range and 1.5% accuracy specifications.
