MAX6718UKZWD3+T

Supervisors Overview

The MAX6718UKZWD3+T is a dual-channel ultra-low-voltage microprocessor supervisor circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.8 V to 5 V and features a maximum operating voltage of 5.5 V. The device provides two independent reset outputs with active-low, push-pull configuration and includes a manual reset input. Key electrical parameters include a typical quiescent current of 15 µA, a reset delay time of 210 ms, and an overvoltage threshold of 1.71 V and 2.375 V. It functions reliably across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel supervision for monitoring multiple power rails simultaneously
• Ultra-low quiescent current consumption suitable for battery-powered applications
• Manual reset input capability for system control flexibility
• Active-low push-pull output drivers for direct interface compatibility

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing reliable power-on reset sequences
• Industrial control units operating in harsh environmental conditions
• Communication equipment utilizing low-voltage logic interfaces

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential counterfeits. Confirm RoHS compliance status via official documentation before integration. Check end-of-life status as this specific part number may be discontinued or subject to limited availability. Ensure packaging specifications match design requirements for surface-mount assembly processes.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required in space-constrained designs. The SOT-23-5 package offers compact footprint advantages for dense PCB layouts. Consider the 15 µA standby current for energy-sensitive applications. Verify that the 210 ms reset delay aligns with system startup timing requirements. Ensure the 1.8 V minimum operating voltage matches the lowest expected supply rail.

Supervisors Part Context

This device belongs to the MAX6718 series of dual uPower supervisors designed for low-voltage digital systems. It complements similar single-channel variants by providing redundant monitoring capabilities in a minimal footprint. The Maxim Integrated portfolio emphasizes reliability and low power consumption for portable and industrial electronics. This specific suffix indicates the lead-free and RoHS-compliant variant of the standard MAX6718 family.
