MAX6355LTUT

Overview

The MAX6355LTUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It features two fixed voltage thresholds of 3.08 V and 4.63 V, monitoring up to three inputs. The device provides an active-low open-drain reset output with a manual reset input and a watchdog timer. It operates within a supply voltage range up to 5.5 V, has a reset delay time of 180 ms, and functions over an extended temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple power-supply voltages with precision factory-set thresholds
• Includes a debounced manual reset input for system control
• Integrates a watchdog timer for fault detection
• Provides active-low open-drain reset outputs

Applications

• Microprocessor system supervision
• Multi-voltage power supply monitoring
• Industrial control systems
• Embedded hardware protection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check current lifecycle status as the part may be discontinued. Ensure package type matches SOT-23-6 specifications before integration into design files.

Selection Notes

Select this component when precise monitoring of specific voltage levels like 3.08 V and 4.63 V is required. Consider the open-drain output configuration and manual reset capability. Evaluate thermal requirements against the -40°C to +85°C operating range.

Part Context

This part belongs to the MAX635x series of dual/triple-voltage supervisors designed to improve system reliability. It replaces discrete components or separate ICs by integrating multiple reset functions into a single small-footprint package, suitable for space-constrained applications.

Replacement Considerations

Check for MAX6355MRUT+T or MAX6355LSUT+T if different threshold voltages are needed. Verify pinout compatibility and electrical characteristics before substituting.
