Product details

It can sit on a motor-drive control board, an engine ECU, or outdoor telecom equipment without derating concerns. The SOT-23-6 package keeps board area small, but the 125°C rating means the part can handle the thermal load near a hot power supply or processor.

RoHS non-compliant — plan accordingly

You may need to source a lead-free equivalent variant in the same family or plan for an exemption. The lifecycle status is Active, so there is no LTB pressure, but the RoHS gap is the main sourcing constraint.

Sourcing and supply

For dual-sourcing resilience, a pin-compatible sibling with the same threshold is available — check its output polarity and timeout to confirm fit.

Frequently asked questions

Is MAX6324HUT46 RoHS compliant?

No, the MAX6324HUT46 is listed as RoHS non-compliant. If your BOM requires RoHS compliance, consider a lead-free variant in the MAX6324 family or plan for an exemption.

What is the difference between MAX6324HUT46 and MAX6323HUT46?

Both are single-channel watchdog circuits in SOT-23-6 with a 4.63V threshold. The primary difference is the output configuration — the MAX6324HUT46 has an active-low, open-drain output, while the MAX6323HUT46 may have a different output polarity or type. Check the respective datasheets for the exact output structure and reset timeout to confirm interchangeability.
