Product details

2.7V threshold and 140 ms timeout — what they mean for the BOM

Push-pull output eliminates the need for an external pull-up resistor, saving one component per supervisor channel on the BOM. Active-low reset polarity matches the majority of MCUs, FPGAs, and SoCs that expect a low-true reset input.

Automotive grade and package fit

AEC-Q100 qualification means the part has passed the automotive stress tests for temperature cycling, ESD, and operating life — a requirement for any component specified into a production vehicle ECU or ADAS board. The SC-70-3 package (SOT-323 footprint) is a compact three-pin surface-mount case suited for dense PCBs where board area is tight.

Sourcing and lifecycle

No last-time-buy or phase-out notice applies. For BOM freeze or dual-source planning, this part is a stable line item with no imminent obsolescence risk.

Frequently asked questions

Is MAX6381XR27D3+ AEC-Q100 qualified?

Yes, the MAX6381XR27D3+ is part of the Automotive, AEC-Q100 series, making it qualified for automotive-grade applications including under-hood and chassis-domain electronics.

What is the reset output type and polarity of MAX6381XR27D3+?

The reset output is active-low with a push-pull, totem-pole stage. It drives a logic-low signal when the monitored voltage falls below the 2.7V threshold and releases high after the 140 ms timeout.

Is MAX6381XR27D3+ suitable for automotive applications?

Yes, the part is AEC-Q100 qualified and rated for the -40°C to 125°C operating temperature range, making it suitable for automotive ECU, ADAS, and other vehicle-mounted electronics.
