MAX6358MSUT

Overview

The MAX6358MSUT+T is a dual-channel voltage supervisor manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent power supply rails to ensure system reliability. The device features an active-low, open-drain reset output and includes a manual reset input for user control. A built-in watchdog timer with timeout detection enhances fault protection. The component operates within a temperature range of -40°C to +85°C and is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Dual-channel voltage supervision for monitoring multiple power rails simultaneously
• Integrated watchdog timer with timeout functionality for enhanced system reliability
• Manual reset input capability allowing external control over the reset state
• Active-low open-drain reset output compatible with various logic families

Applications

• Portable equipment requiring multi-voltage monitoring
• Battery-powered systems needing power loss detection
• Embedded controllers requiring watchdog protection
• Industrial control units demanding high reliability

Procurement Notes

Verify the exact suffix (e.g., +T) against the manufacturer's current datasheet to confirm packaging and RoHS compliance status. Confirm availability as this series may be subject to discontinuation or lifecycle changes. Ensure the specific threshold voltages match the design requirements before procurement.

Selection Notes

Select this component when dual-rail supervision and watchdog functionality are required in a small footprint. Verify that the monitored voltage levels fall within the supported input range. Consider the open-drain output configuration for proper pull-up resistor selection in the target circuit design.

Part Context

This part belongs to the MAX635x family of voltage supervisors from Maxim Integrated, now part of Analog Devices. These devices are designed for portable and battery-operated applications where power management and system stability are critical. The family offers various threshold options and package configurations to suit different design constraints.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX635x family with matching threshold voltages. Verify functional equivalence regarding watchdog timeout periods and reset delay times. Consult the manufacturer's obsolescence notices for recommended upgrade paths if this specific variant is discontinued.
