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 provides an active-low, open-drain output. Packaged in a compact SOT-23-5 format, it supports surface-mount installation.

Supervisors Feature Summary

• Monitors power supply voltage levels against a factory-programmed threshold
• Includes a manual reset input for system control
• Provides an active-low, open-drain reset output signal

Supervisors Applications

• Personal computer systems monitoring multiple power rails
• Portable applications requiring low supply current
• Systems needing protection against power supply transients

Supervisors Procurement Notes

Verify the exact suffix configuration when ordering, as variants like MAX6309EUK46D3+T exist with different packaging or compliance statuses. Confirm availability through authorized distributors, as stock levels fluctuate. Ensure the selected part matches the required lead-free status if applicable to your assembly process.

Supervisors Selection Notes

Select this component when a specific 4.63V threshold is required for system supervision. Consider the SOT-23-5 package size for space-constrained designs. Verify that the manual reset feature aligns with the system's control logic requirements before finalizing the design.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin, multiple-input programmable reset ICs. These devices are engineered to ignore fast transients on monitored supplies, making them suitable for noisy environments. The family offers various factory-programmed thresholds ranging from 2.5V to 5.0V.

Supervisors Replacement Considerations

Check for MAX6309EUK46D3+T as a potential alternative with tape-and-reel packaging. Verify pinout compatibility and electrical specifications before substitution.
