Active-low reset is the convention for most MCUs and SoCs — the supervisor pulls the RST pin low on fault and releases it after the timeout. ## Temperature grade and package — fits industrial and automotive environments A sensor node or ECU that sees 105°C on a summer-grade road still has 20°C of margin before the supervisor's own silicon hits its limit. The SOT-23-5 package (SC-74A, SOT-753 footprint) is a standard five-pin small-outline transistor package. It reflows with the same profile as the rest of the board — no special handling, no moisture-sensitive level above MSL 1 for most reel lots. The pinout is unambiguous: pin 1 is GND, pin 5 is VCC, and the reset output is on pin 4, which makes manual probing or a field swap straightforward if the board is laid out with a test point. RoHS3 compliant — no exemption-based paperwork needed for EU or California market entry.","metaTitle":"MAX823MEUK+T Simple Reset/Power-On Reset, 4.38V Threshold","metaDescription":"Active production MAX823MEUK+T supervisor IC.
