MAX6316MUK46CY+

Supervisors Overview

The MAX6316MUK46CY+ is a microprocessor supervisory circuit from the MAX6316–MAX6322 family, designed to monitor power supplies and processor activity. It features a fixed reset threshold voltage of 4.6 V with an overvoltage threshold of 4.699 V. The device operates within a supply voltage range up to 5.5 V and consumes 10 µA of quiescent current. It provides an active low, push-pull reset output with a 200 ms timeout period. Integrated features include a watchdog timer and manual reset input. The component supports operation across an extended temperature range from -40°C to +125°C and is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary

• Integrates a watchdog timer for monitoring microprocessor activity alongside voltage supervision
• Includes a manual reset input for system control flexibility
• Provides an active low, push-pull reset output configuration
• Operates at ultra-low quiescent current suitable for battery-powered applications

Supervisors Applications

• Monitoring power supplies in digital systems
• Microprocessor activity supervision
• Battery-operated electronic devices requiring low power consumption

Supervisors Procurement Notes

Verify the specific suffix CY against official Analog Devices documentation to confirm temperature grade and packaging details. Confirm RoHS compliance status as indicated in the datasheet. Check production lifecycle status, as availability may be limited or discontinued. Ensure the SOT-23-5 footprint matches the target PCB design requirements before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for system supervision. The integrated watchdog and manual reset features reduce external component count. Verify that the 200 ms timeout meets system startup timing requirements. Ensure the operating temperature range aligns with the application environment constraints.

Supervisors Part Context

This part belongs to the MAX6316–MAX6322 family of 5-pin μP supervisory circuits. These devices offer various combinations of reset outputs and thresholds. The MAX6316 variant specifically includes watchdog functionality. The family provides factory-trimmed thresholds ranging from 2.5 V to 5 V in 100 mV increments.

Supervisors Replacement Considerations

Consult the MAX6316–MAX6322 selector guide for alternative parts with different thresholds or output types. Verify pin compatibility and electrical specifications before substituting.
