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.","metaTitle":"MAX6381XR27D3+ Power Supply Monitor, AEC-Q100, SC-70-3","metaDescription":"MAX6381XR27D3+ single-voltage power supply monitor from Maxim Integrated.
