MAX6316MUK31CY

Supervisors Overview

The MAX6316MUK31CY is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5V and features a fixed reset threshold of 3.1V. The device monitors a single input and provides an active low, push-pull reset output. It includes manual reset functionality and a watchdog timer with a 200ms reset delay time. The component is housed in a SOT-23-5 surface-mount package and supports operation from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer for monitoring processor activity alongside power supply supervision.
• Provides manual reset capability via an external button interface.
• Delivers a push-pull reset output signal for robust logic interfacing.

Supervisors Applications

• Digital system power supply monitoring
• Microprocessor activity supervision
• Embedded controller reset management

Supervisors Procurement Notes

Verify the specific suffix CY against official datasheets to confirm temperature grade and packaging details. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the ordering information matches the required threshold voltage and output configuration for the target design.

Supervisors Selection Notes

Select this component when a single-supervision channel with both watchdog and manual reset is required. The push-pull output suits applications needing strong drive capability. Verify that the 3.1V threshold aligns with the monitored rail and that the industrial temperature range meets environmental requirements.

Supervisors Part Context

This part belongs to the MAX6316-MAX6322 family of 5-pin uP supervisory circuits. These devices are designed to monitor power supplies and microprocessor activity in digital systems. The family offers various combinations of reset outputs and features factory-trimmed threshold voltages.

Supervisors Replacement Considerations

Check for other MAX6316 variants with different threshold voltages or output types if the 3.1V threshold or push-pull output does not match the design requirements. Verify pin compatibility before substituting with similar supervisory ICs from the same manufacturer.
