MAX6318LHUK31AY-T

Supervisors Overview

The MAX6318LHUK31AY-T is a microprocessor supervisory circuit in a SOT-23-5 package. It monitors one input with a fixed threshold of 3.08V and an overvoltage threshold of 3.126V. The device features active high and low push-pull outputs, manual reset capability, and a reset delay of 1.4 ms. Operating voltage ranges up to 5.5V with 3 µA supply current. Accuracy is 1.5%, and it functions between -40°C and +125°C.

Supervisors Feature Summary

• Provides manual reset input for system control
• Delivers active high and low push-pull reset signals
• Monitors single power supply channel

Supervisors Applications

• Microprocessor power supply supervision
• Digital system reset generation
• Embedded controller monitoring

Supervisors Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance requirements as the specific suffix indicates non-compliant tin-lead finish. Validate package integrity and pin configuration against SOT-23-5 specifications before integration into production designs.

Supervisors Selection Notes

Select this part when fixed 3.08V threshold and bidirectional push-pull outputs are required. Ensure compatibility with systems needing manual reset functionality. Verify that the 5.5V maximum operating voltage meets system rail requirements. Consider thermal performance within the specified -40°C to +125°C range for environmental suitability.

Supervisors Part Context

Part of the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. This series offers various combinations of reset outputs and watchdog features. The MAX6318 variant specifically provides manual reset and push-pull outputs without watchdog timer functionality, distinguishing it from other family members.
