For a 5V rail, this threshold sits in the typical undervoltage region, catching brownout conditions before the downstream logic enters an undefined state. The output drives directly into the reset input of a microcontroller or FPGA, saving a resistor and one BOM line. ## Package and temperature grade for the BOM Housed in a 3-lead SC-70 (SOT-323 footprint), the MAX6378XR46+ is a surface-mount device occupying minimal board area. The supplier device package is SC-70-3 — a common, widely second-sourced footprint that fits standard pick-and-place without special handling.","metaTitle":"MAX6378XR46+ Voltage Detector, 4.63V Threshold, SC-70","metaDescription":"MAX6378XR46+ voltage detector from Analog Devices.
