MAX6316LUK45CX+

Supervisors Overview

The MAX6316LUK45CX+T is a microprocessor supervisory circuit from the MAX6316 family, designed to monitor power supplies and processor activity. It features a fixed reset threshold voltage of 4.5V with an active-low push-pull output. The device includes a watchdog timer and manual reset input, housed in a compact SOT-23-5 package. It operates within a supply voltage range up to 5.5V and supports an industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrated watchdog timer for monitoring microprocessor activity
• Manual reset input for system control
• Active-low push-pull reset output stage
• Factory-trimmed reset threshold voltage

Supervisors Applications

• Digital system power supply supervision
• Microprocessor activity monitoring
• Industrial control systems requiring extended temperature operation

Supervisors Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as distributor listings may vary. Confirm availability status directly with the manufacturer or authorized partners due to potential limited stock conditions. Ensure the component meets RoHS compliance requirements for your specific application standards before finalizing procurement.

Supervisors Selection Notes

Select this part when a 4.5V threshold is required for single-supervision applications. The SOT-23-5 package suits space-constrained designs. Verify that the active-low push-pull output aligns with the target logic interface. Consider the watchdog timeout period compatibility with the system's clock frequency.

Supervisors Part Context

This component belongs to the MAX6316–MAX6322 family of 5-pin µP supervisory circuits. These devices are characterized by their ability to ignore fast negative transients on VCC and provide valid resets down to 1V. The family offers various threshold voltages and output configurations to suit diverse digital system requirements.

Supervisors Replacement Considerations

Other variants within the MAX6316 series (e.g., MAX6316LUKxxCX+T) offer different threshold voltages. Cross-reference the specific threshold voltage and output type to ensure functional equivalence. Consult the official datasheet for pin-compatible alternatives within the same package.
