MAX6358SYUT+T

Overview

The MAX6358SYUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors two or three power supply rails and provides reset signals when voltages drop below preset thresholds. The device features an active low, open-drain output type with a manual reset input and a watchdog timer function. It operates within a supply voltage range up to 5.5V and includes a reset delay time of 180 ms. The component is housed in a SOT-23-6 surface-mount package and supports operation across an extended temperature range.

Feature Summary

• Monitors multiple power supply rails for system reliability
• Includes a watchdog timer for fault detection
• Features a manual reset input for user control

Applications

• Embedded systems requiring multi-rail power supervision
• Microprocessor-based designs needing voltage monitoring
• Industrial equipment with extended temperature requirements

Procurement Notes

Verify component authenticity through authorized distributors due to potential counterfeit risks. Confirm package integrity and pin alignment before soldering. Check datasheet revisions for updated electrical characteristics. Ensure storage conditions comply with moisture sensitivity levels. Validate compatibility with existing board layouts and thermal management strategies.

Selection Notes

Evaluate threshold voltage accuracy against system requirements. Consider package size constraints for PCB layout. Assess current consumption impact on battery life if applicable. Verify temperature range suitability for operational environments. Compare manual reset functionality needs against automatic recovery options.

Part Context

Part of the MAX6351–MAX6360 series offering precise multi-voltage supervision. Designed to replace discrete components for improved accuracy and reliability. Utilizes factory-set thresholds for consistent performance across applications. Supports both dual and triple voltage monitoring configurations in compact packages.

Replacement Considerations

Direct substitutes include MAX6358LSUT+T and MAX6358LTUT+T from the same manufacturer family. Verify pinout compatibility and threshold voltage specifications before substitution. Check for any differences in watchdog timer functionality or reset delay times.
