MAX6316LUK46CY+T

Supervisors Overview

The MAX6316LUK46CY+T is a microprocessor supervisory circuit in a 5-pin SOT-23 package. It monitors a single power supply with a fixed threshold voltage of 4.6V and an overvoltage threshold of 4.699V. The device features an active-low push-pull reset output, manual reset input, and watchdog timer. It operates within a supply range up to 5.5V, consumes 10µA, and has a reset delay of 200ms. Operating temperatures range from -40°C to +125°C.

Supervisors Feature Summary

• Integrated watchdog timer for monitoring processor activity
• Manual reset input capability for system control
• Active-low push-pull reset output stage
• Designed to ignore fast negative transients on VCC

Supervisors Applications

• Digital system power supply supervision
• Microprocessor activity monitoring
• Portable applications requiring low current consumption

Supervisors Procurement Notes

Verify the specific suffix CY against official Analog Devices documentation to confirm package type and temperature grade. Confirm availability status as distribution channels may indicate limited stock or special order requirements. Ensure the part number matches the exact threshold voltage and output configuration required for the design.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-supervision applications. Consider the 10µA quiescent current for battery-sensitive designs. Verify that the active-low push-pull output aligns with the target logic interface. Check if the integrated watchdog and manual reset features meet the system reliability requirements without external components.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices offer various combinations of reset outputs, watchdog timers, and manual resets. The family provides factory-trimmed thresholds from 2.5V to 5V in 100mV increments, packaged in a miniature SOT-23 form factor for space-constrained designs.

Supervisors Replacement Considerations

Other MAX6316 variants with different threshold voltages (e.g., LUK29, LUK39) serve as functional substitutes if the voltage level differs. Cross-reference the output stage type and timeout periods to ensure compatibility.
