When the monitored supply drops below that threshold, the open-drain output pulls low and holds the reset state for a minimum of 1 ms after the rail recovers — long enough for most MCUs and SoCs to complete their internal boot sequence before the core is released. A microcontroller in an outdoor telecom cabinet or a motor-drive control board that sees 105°C on a summer afternoon still has margin before the supervisor's own temperature derating becomes a concern. ## SOT-23-4 package and surface-mount board integration The four-pin footprint — VCC, GND, RESET, and a no-connect — keeps routing simple on a two-layer board; the open-drain output requires a pull-up resistor to the logic supply of the supervised device. If a board already carries a SOT-23-4 supervisor from this series, the layout is directly compatible.","metaTitle":"MAX6315US44D1+ Simple Reset/Power-On Reset, 4.39V Threshold","metaDescription":"MAX6315US44D1+ active-low open-drain reset IC, 4.39V threshold, SOT-23-4, -40°C to +125°C.

The MAX6315US44D1+ monitors a 4.39 V rail; a sibling with a different threshold (e.g., 2.93 V or 4.63 V) uses the same SOT-23-4 pinout and open-drain output, so a board layout change is not required — only the BOM line threshold needs to match the supervised supply."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6315US44D1~3","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6315US44D1~3 when reusing this data.
