MAX6316MUK46AY

Supervisors Overview

The MAX6316MUK46AY is a microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.62V to 5.5V and features a fixed reset threshold voltage of 4.6V. The device provides an active-low, push-pull reset output with a typical delay time of 200ms. It integrates both a watchdog timer and manual reset functionality. The component is housed in a compact SOT-23-5 surface-mount package and supports operation across an extended industrial temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates watchdog timer and manual reset capabilities for comprehensive system monitoring
• Provides active-low push-pull reset output for direct logic interfacing
• Operates over an extended industrial temperature range suitable for harsh environments

Supervisors Applications

• Microprocessor power supply supervision
• Watchdog timer implementation in digital systems
• Manual reset control circuits

Supervisors Procurement Notes

Verify the specific suffix 'A' against official datasheets to confirm temperature grade or binning variations. Confirm RoHS compliance status via current manufacturer documentation. Validate availability through authorized distributors as stock levels fluctuate. Ensure the SOT-23-5 footprint matches the target PCB design constraints.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required for single-supervision applications. The integrated watchdog and manual reset features reduce external component count compared to basic supervisors. Verify that the active-low push-pull output drives the connected processor reset pin correctly within the system's voltage logic levels.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices are designed to monitor power supplies and microprocessor activity. The family offers various combinations of reset outputs and thresholds, with this specific model providing a 4.6V threshold with watchdog and manual reset functions.

Supervisors Replacement Considerations

Check for other MAX6316 variants with different threshold voltages if the 4.6V level is not optimal. Verify compatibility with MAX6319 or MAX6320 series if additional features like battery backup switches are needed.
