If your rail dips below 4.38V for longer than the 20ms minimum reset timeout, the active-high reset output asserts. The 20ms debounce filters out short glitches but catches a sustained brownout or regulator dropout. The push-pull, totem-pole output drives the reset line directly without an external pull-up resistor — one less component on the board. Active-high polarity means it pulls high when the monitored voltage is valid; a logic-high on the reset pin enables the system, and a low (or high-impedance) holds it in reset. ## SC-70-3 package — board-fit checklist Surface-mount assembly with standard lead-free profiles works, though note the part is marked RoHS non-compliant, so it carries the legacy tin-lead finish. The wide temperature grade means the threshold accuracy and reset timeout stay within spec across the full span — no derating needed for a hot enclosure or cold start.","metaTitle":"MAX6382XR44D2 Simple Reset/Power-On Reset, 4.38V Threshold","metaDescription":"MAX6382XR44D2 supervisor IC, active-high reset, push-pull output, 20ms timeout, SC-70-3.
