MAX6358MSUT-T

Overview

The MAX6358MSUT-T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1V to 5.5V and monitors two independent input voltages. The device features active-low, open-drain reset outputs with a fixed reset delay time of 180ms. It includes a manual reset input and a watchdog timer function. The component is housed in a compact SOT-23-6 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel voltage monitoring for independent power rails
• Integrated watchdog timer with defined timeout periods
• Debounced manual reset input compatible with TTL/CMOS logic

Applications

• Portable equipment requiring multiple voltage domains
• Battery-powered systems needing low quiescent current
• Embedded controllers requiring reliable power supervision

Procurement Notes

Verify the specific suffix against official datasheets, as variations exist within the MAX6358 family. Confirm availability status directly with authorized distributors, as supply constraints may apply. Ensure the selected variant matches the required threshold voltages and output configuration for the target design.

Selection Notes

Select this component when simultaneous monitoring of two distinct voltage levels is required in a small footprint. Consider the open-drain output type for compatibility with various logic families. Evaluate the 20µA quiescent current against system power budgets for battery-operated applications.

Part Context

This part belongs to the MAX635x series of multi-voltage supervisors designed to enhance system reliability. These devices replace discrete components, offering precise factory-set thresholds. The series supports various packages and threshold combinations to accommodate diverse industrial and consumer electronics designs.

Replacement Considerations

Cross-reference with MAX6358LSUT+T or MAX6358LTUT+T for alternative threshold options within the same package. Verify pinout compatibility before substitution. Check for updated lead-free variants if environmental compliance is required.
