MAX809LEXR

Supervisors Overview

The MAX809LEXR is a microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features a push-pull active-low RESET output and operates with supply voltages ranging from 1.2V to 5.5V. The device monitors a specific threshold voltage of 4.63V, ensuring reliable reset generation for system protection. Packaged in an SC-70-3 (SOT-323) surface-mount case, it provides efficient regulation and monitoring for optimal system performance.

Supervisors Feature Summary

• Monitors power supply voltage levels to ensure system stability
• Generates active-low reset signal via push-pull output
• Operates within a wide supply voltage range of 1.2V to 5.5V

Supervisors Applications

• Microprocessor system power supply monitoring
• Digital system supervision
• +5V power rail monitoring

Supervisors Procurement Notes

Verify the exact suffix (e.g., LEXR vs LEXR+T) against official Analog Devices documentation to confirm package type and tape-and-reel specifications. Ensure the component matches the required 4.63V threshold and SC-70-3 footprint before integration into design schematics.

Supervisors Selection Notes

Select this component when a fixed 4.63V threshold is required for +5V system monitoring. The SC-70-3 package suits space-constrained designs. Confirm compatibility with the target microprocessor's reset input requirements and operating voltage range.

Supervisors Part Context

Part of the MAX803/MAX809/MAX810 family of microprocessor supervisory circuits manufactured by Maxim Integrated (Analog Devices). These devices are standard solutions for power management supervision in embedded and digital applications.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the MAX803/MAX809/MAX810 series that match the 4.63V threshold and SC-70-3 package. Verify electrical characteristics before substitution.
