MAX6358TWUT

Overview

The MAX6358TWUT+T is a dual-channel voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent supply voltages with fixed thresholds of 3.08 V and 4.63 V. The device features an active-low, open-drain reset output and includes a manual reset input for system control. It incorporates a watchdog timer to enhance reliability and provides a reset delay time of 180 ms. Designed for surface-mount installation in a compact SOT-23-6 package, it operates within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-channel voltage supervision with fixed threshold monitoring
• Integrated watchdog timer for system fault detection
• Manual reset input capability for controlled system recovery

Applications

• Microprocessor power supply monitoring
• Embedded system voltage supervision
• Industrial control circuit protection

Procurement Notes

Verify the exact suffix configuration against official documentation, as variations exist within the MAX6358 family. Confirm current availability status, as specific variants may be discontinued or subject to limited supply constraints. Ensure compatibility with existing PCB footprints and thermal requirements before procurement.

Selection Notes

Select this component when dual-voltage monitoring with integrated watchdog functionality is required. Verify that the fixed threshold values align with target supply rails. Consider the open-drain output requirement for pull-up resistor implementation. Evaluate package size constraints against the SOT-23-6 footprint availability.
