It lives in the tiny SC-70-3 package (SOT-323 footprint), which makes it a fit for space-constrained designs like battery-powered sensors, portable instruments, or low-power wireless nodes where every square millimeter counts. ## Threshold and temperature — what matters for a reliable reset The 4.38V threshold is a good match for monitoring a 5V supply rail — it triggers before the rail drops enough to cause logic glitches, giving the system time for an orderly shutdown. With a single monitored voltage, this part is a straightforward supervisor for one critical rail. ## Package and hand-solderability SC-70-3 is a three-lead package with 0.65mm pitch — hand-solderable with a fine tip and steady hands, though a hot-air station makes it easier.","metaTitle":"MAX6378XR44+ Voltage Detector, 4.38V Threshold, SC-70","metaDescription":"MAX6378XR44+ from Analog Devices: voltage detector, 4.38V threshold, active-low push-pull output, SC-70-3.
