MAX6806XR46

Supervisors Overview

The MAX6806XR46 is a precision voltage detector manufactured by Analog Devices Inc./Maxim Integrated, designed for accurate monitoring of power supplies in digital systems. It features an active-low, push-pull RESET output and operates within a supply voltage range down to 1V. The device asserts a reset signal whenever the supply voltage falls below the factory-preset threshold of 4.6V, which has an accuracy of ±2%. Internal hysteresis ensures stable switching under varying conditions. It is available in surface-mount packages including SC-70 and SOT-23, with a standard reset timeout of 30µs.

Supervisors Feature Summary

• Provides precise monitoring of power supply voltages with factory-preset thresholds
• Features an active-low, push-pull RESET output for direct interface compatibility
• Includes internal hysteresis to ensure stable switching and prevent false triggers
• Operates reliably with supply voltages down to 1V

Supervisors Applications

• Monitoring power supplies in digital systems
• Circuit reliability enhancement through automated reset generation
• Embedded systems requiring precise voltage supervision

Supervisors Procurement Notes

Verify component authenticity and datasheet alignment before integration. Confirm package type and threshold voltage specifications match design requirements. Check for obsolescence status as some variants may be discontinued. Ensure RoHS compliance documentation is available for regulatory adherence. Validate operating temperature range suitability for the intended environment.

Supervisors Selection Notes

Select this component when a push-pull output is required for driving logic inputs directly. The 4.6V threshold suits applications monitoring 5V or similar nominal rails. Consider the MAX6807 if an active-high output is needed instead. Evaluate package size constraints against SC-70 or SOT-23 availability. Verify that the 30µs reset timeout meets system startup timing requirements.

Supervisors Part Context

The MAX6806 belongs to the MAX6806/MAX6807/MAX6808 family of precision voltage detectors. This series eliminates external components and adjustments by integrating preset thresholds and hysteresis. The MAX6806 specifically offers an active-low push-pull output, distinguishing it from the open-drain MAX6808 and active-high MAX6807. All variants share similar accuracy and operating characteristics.

Supervisors Replacement Considerations

Direct substitutes include MAX6806XR46+T (tape and reel version) and MAX6806SA46+ (SOIC-8 package). For active-high output needs, consider MAX6807XR46. For open-drain output, consider MAX6808XR46. Verify pinout compatibility and threshold voltage matching when substituting.
