MAX6718UKSHD3+T

Supervisors Overview

The MAX6718UKSHD3+T is a dual-channel voltage supervisory circuit from the MAX6718 series, 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 inputs with an active low, push-pull output type and includes manual reset functionality. It has a reset delay time of 210 ms and consumes 15 uA of quiescent current. Overvoltage thresholds are set at 1.35 V and 1.62 V. The component is housed in an SOT-23-5 package and supports industrial temperature ranges from -40°C to +85°C.

Supervisors Feature Summary

• Dual-channel voltage supervision for independent monitoring of two power rails
• Ultra-low quiescent current consumption for extended battery life
• Manual reset input capability for system control flexibility
• Compact SOT-23-5 surface-mount packaging

Supervisors Applications

• Portable electronic devices requiring multi-rail power monitoring
• Battery-powered systems needing low standby current
• Industrial control units with strict size constraints
• Embedded systems requiring manual reset capabilities

Supervisors Procurement Notes

Verify the exact suffix HD3 against your design requirements, as it defines specific overvoltage thresholds (1.35 V, 1.62 V). Confirm availability status, as this part may be subject to limited supply or discontinuation. Ensure the SOT-23-5 package fits your PCB layout. Check RoHS compliance documentation if required for your region. Cross-reference with the official datasheet for thermal and electrical limits before finalizing procurement.

Supervisors Selection Notes

Select this component when dual-voltage monitoring is required in a minimal footprint. The 15 uA quiescent current makes it suitable for energy-sensitive applications. Verify that the 1.35 V and 1.62 V overvoltage thresholds align with your system's protection needs. Consider the 210 ms reset delay for timing compatibility. The manual reset feature adds control flexibility compared to auto-reset-only variants.

Supervisors Part Context

This part belongs to the MAX6718 family of dual uPower supervisors. It shares the core architecture with other MAX6718 variants but differs in threshold settings and package options. The UKVDD3, UKRVD3, and AUKSVD3 variants offer different overvoltage thresholds and temperature ranges. The HD3 suffix specifically denotes the 1.35 V/1.62 V overvoltage configuration.

Supervisors Replacement Considerations

Direct substitutes include other MAX6718 variants with similar dual-channel functionality, such as MAX6718UKVDD3+T or MAX6718UKRVD3+T, provided their overvoltage thresholds match your design. Verify pinout compatibility and reset delay times. No direct cross-brand replacements are confirmed in public data.
