MAX6309UK46D3

Supervisors Overview

The MAX6309UK46D3 is a CMOS microprocessor supervisory circuit designed to monitor power supplies. It features a fixed reset threshold voltage of 4.63V and includes a manual reset input. The device operates within a supply voltage range up to 5.5V and consumes low supply current, making it suitable for portable applications. It asserts a system reset if the monitored supply falls outside the programmed threshold.

Supervisors Feature Summary

• Monitors single power supply with factory-programmed threshold
• Includes manual reset input for system control
• Designed to ignore fast transients on monitored supply

Supervisors Applications

• Personal computer systems monitoring 5V and 3.3V supplies
• Portable electronic devices requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and lead-free specifications against current datasheet revisions. Ensure package integrity matches SOT-23-5 requirements before integration into design.

Supervisors Selection Notes

Select this part when a fixed 4.63V threshold is required for single-supply monitoring. Consider the manual reset feature for systems needing external reset control. Evaluate operating temperature range compatibility with application environment constraints.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-pin multiple-input programmable reset ICs. These CMOS supervisory circuits are optimized for monitoring multiple power rails in complex digital systems while maintaining low power consumption.

Supervisors Replacement Considerations

Cross-reference with other MAX6309 variants having different threshold voltages if 4.63V is unsuitable. Verify pinout compatibility with existing PCB layouts when substituting.
