MAX6412UK46+T

Supervisors Overview

The MAX6412UK46+T is a low-power, single-voltage microprocessor reset circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.6 V to 5 V and features a fixed threshold voltage of 4.6 V. The device provides an active-low, push-pull reset output with a manual reset input capability. It utilizes a capacitor-adjustable reset timeout delay mechanism for flexible timing control. The component is housed in a compact SOT-23-5 surface-mount package and is rated for operation across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Capacitor-adjustable reset timeout delay allows customizable response timing
• Manual reset input enables external system control over reset state
• Active-low push-pull output ensures robust drive capability

Supervisors Applications

• Monitoring power supply voltages in embedded systems
• Providing reset signals for microprocessors and digital logic
• Ensuring system stability during power-up and power-down sequences

Supervisors Procurement Notes

Verify the specific suffix UK46 corresponds to the required 4.6 V threshold and active-low configuration. Confirm the presence of the manual reset pin functionality as indicated by the part designation. Ensure compatibility with the target PCB footprint for the SOT-23-5 package. Check for RoHS compliance documentation if required by project specifications.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required alongside manual reset control. The capacitor-adjustable timeout offers flexibility compared to fixed-delay supervisors. Consider the low quiescent current for battery-operated applications. Verify that the active-low output polarity matches the receiving logic inputs.

Supervisors Part Context

This part belongs to the MAX6412-MAX6420 family of low-power reset circuits. The MAX6412 variant specifically denotes a single-voltage monitor with a fixed threshold and manual reset input. The UK46 suffix identifies the specific threshold voltage and output type within the Maxim Integrated product line.

Supervisors Replacement Considerations

Direct substitutes include other parts from the MAX6412 series with matching threshold voltages and output configurations. Verify pinout compatibility for the SOT-23-5 package before substitution.
