They share the same SC-70-4 footprint and pinout, but the MAX6389 adds the adjustable second channel. If your design needs two rails monitored, the MAX6389 is a functional superset; if you only need one, the MAX6388 is the simpler choice."},{"question":"What is the reset output type of MAX6389XS44D3+T?","answer":"The reset output is active low, open drain. That means it pulls to ground when a fault is detected, and you need an external pull-up resistor to the logic supply voltage of the downstream device."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX6389XS44D3T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX6389XS44D3T when reusing this data.
