MAX6318LHUK31AY

Supervisors Overview

The MAX6318LHUK31AY+T is a microprocessor supervisory circuit in a SOT-23-5 package. It monitors a single input with a fixed threshold voltage of 3.08V and an overvoltage threshold of 3.126V. The device features active high and active low push-pull reset outputs, a manual reset input, and a watchdog timer. It operates within a supply voltage range up to 5.5V, maintains accuracy within 1.5%, and consumes 3µA of quiescent current. The reset delay time is 1.4ms, and it functions across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer for monitoring processor activity alongside power supply supervision.
• Provides dual reset outputs with configurable active high and active low logic states.
• Includes a manual reset input for external system control capabilities.

Supervisors Applications

• Microprocessor power supply monitoring
• Digital system supervisor circuits
