Product details

Industrial temperature range, SOT-23-6 footprint

Rated for -40°C to 85°C ambient, this part fits industrial control, telecom infrastructure, and outdoor equipment that sees seasonal temperature swings but not the extended range of under-hood automotive. The SOT-23-6 package occupies minimal board area and is a common footprint for supervisor ICs, making it straightforward to drop into an existing layout or to second-source against a similar pin-compatible part.

Active production status and sourcing posture

The MAX6363HUT46 carries an active lifecycle status, so there is no last-time-buy or discontinuation notice to plan around. It is RoHS non-compliant, which matters for EU-market builds or any BOM that requires RoHS conformance — verify your exemption or plan for a compliant alternate if needed.

Frequently asked questions

What is the reset timeout of MAX6363HUT46?

The reset timeout is a minimum of 150ms. After the monitored voltage rises above the 4.63V threshold, the reset output stays asserted for at least 150ms to allow the system power and clock to settle.

Is MAX6363HUT46 active high or low reset?

Active high. The reset output goes high when the monitored voltage drops below the threshold. Because the output is open-drain, an external pull-up resistor to the logic rail is required to generate the high level.

What are the equivalent parts for MAX6363HUT46?

Pin-compatible equivalents exist within the MAX6363 family that differ only by threshold voltage option — for example, the MAX6363HUT29 monitors a 2.93V rail instead of 4.63V. For a direct 4.63V active-high drop-in, check the MAX6363 series variants with the same HUT suffix; the datasheet threshold table lists the full set. No single universal equivalent covers all thresholds, so match the voltage code to your rail.
