MAX6718UKYHD3+T

Supervisors Overview

The MAX6718UKYHD3+T is a dual-channel ultra-low-power voltage supervisor manufactured by Analog Devices Inc. (Maxim Integrated). 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 monitors two independent input voltages with specific overvoltage thresholds of 1.35 V and 1.62 V. It provides an active low, push-pull output and includes a manual reset function. The reset delay time is specified at 210 ms, while the quiescent current is 15 uA. It is housed in a compact SOT-23-5 package and supports surface-mount installation across an industrial temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel voltage supervision for monitoring multiple power rails simultaneously

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability upon receipt. Check for moisture sensitivity level requirements during storage and handling. Ensure proper ESD precautions are observed during assembly. Validate part markings against official datasheet specifications to prevent counterfeit risks.

Supervisors Selection Notes

Select this component when dual voltage monitoring is required in a minimal footprint. Consider the specific overvoltage thresholds of 1.35 V and 1.62 V for compatibility with target rail voltages. Evaluate the 15 uA quiescent current impact on overall system efficiency. Verify that the active low push-pull output aligns with downstream logic requirements. Assess thermal performance within the -40°C to +85°C operational range.

Supervisors Part Context

This device belongs to the MAX6718 series of microprocessor supervisory circuits designed for low-voltage applications. It complements other Maxim Integrated supervisors by offering dual-channel monitoring in a small form factor. The series typically targets portable electronics and industrial control systems where power efficiency and reliability are critical. Related parts may include single-channel variants or those with different threshold configurations.

Supervisors Replacement Considerations

Consult official cross-reference guides for verified substitutes. Ensure replacement parts match the SOT-23-5 package and electrical characteristics. Verify compatibility with existing circuit design parameters before implementation.
