A motor-drive control board sitting next to a hot inverter or a battery-management module under the hood both stay within the operating range without derating. Housed in a 5-pin SOT-23, the footprint matches the industry-standard SC-74A land pattern. The SOT-23-5 package is a common choice for compact supervisor placement near the processor's supply pin, keeping the sense trace short and reducing noise coupling into the threshold comparator.","metaTitle":"MAX6821LUK+T Simple Reset/Power-On Reset, 4.63V Threshold","metaDescription":"MAX6821LUK+T from Analog Devices: Active-high reset supervisor, 4.63V threshold, 140ms timeout.
