Product details

4.38V threshold supervisor in SC-70-3

The open-drain output stays low for a minimum of 100ms after the rail returns above the threshold, providing a clean power-on reset pulse for microcontrollers, DSPs, or other logic devices. Housed in a 3-pin SC-70 package (also compatible with SOT-323), it is a space-saving choice for compact PCB layouts where board area is tight.

Industrial temperature range and mounting

Surface-mount assembly is standard for the SC-70-3 footprint, and the open-drain output allows the reset signal to be pulled up to a different voltage than the monitored rail—useful when the supervisor runs from a 5V rail but the processor core is at 3.3V.

Frequently asked questions

Does MAX6348XR44 have an active low reset?

Yes, the reset output is active low. The open-drain output pulls low when the monitored voltage drops below the 4.38V threshold and remains low for the 100ms minimum reset timeout after the voltage recovers.
