MAX6718UKYHD3+

Supervisors Overview

The MAX6718UKYHD3+T is a dual ultra-low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two independent voltage inputs and provides reset signals when thresholds are exceeded. The device operates within a supply voltage range of 1.8 V to 5 V, with specific threshold options available from 900 mV to 3.3 V. It features an active low push-pull output and supports manual reset functionality. The component is housed in a compact SOT-23-5 surface-mount package and operates reliably across a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel voltage monitoring for independent power rails
• Active low push-pull output driver for direct logic interfacing
• Manual reset capability for system initialization control
• Ultra-low quiescent current consumption for battery efficiency

Supervisors Applications

• Portable electronic devices requiring multi-rail power supervision
• Battery-operated systems needing extended operational life
• Embedded controllers managing multiple voltage domains
• Industrial equipment operating in wide temperature environments

Supervisors Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation to ensure correct threshold voltages and package type. Confirm availability status as distribution channels may list limited or obsolete stock. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check RoHS compliance certificates if required for specific regulatory standards. Validate lead times through official supplier channels before finalizing procurement plans.

Supervisors Selection Notes

Select this component when dual voltage monitoring is required in space-constrained designs. Ensure the available threshold ranges match the monitored rail voltages precisely. Consider the push-pull output drive strength for downstream logic compatibility. Verify that the manual reset feature aligns with the system's startup sequence requirements. Evaluate the operating temperature range against the intended application environment.

Supervisors Part Context

This part belongs to the MAX6718 series of dual ultra-low-voltage supervisors. It shares architectural similarities with other Maxim Integrated supervisory circuits but offers specific dual-input monitoring capabilities. The series is designed for applications where power integrity is critical and low current consumption is prioritized over high-speed switching performance.
