It will not assert reset on a 3.3V rail because the threshold sits above the nominal supply voltage. For 3.3V supervision, look for a supervisor with a threshold near 2.93V or 3.08V in the same family."},{"question":"What is the reset timeout of TPS3801T50DCKRG4?","answer":"The reset timeout is a minimum of 120ms. The processor is held in reset for at least that duration after the supply crosses the threshold, giving the oscillator and core time to stabilise."},{"question":"Is TPS3801T50DCKRG4 active low or active high?","answer":"Active low — the reset output goes low when the monitored voltage falls below the threshold and stays low through the timeout period after recovery."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3801T50DCKRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3801T50DCKRG4 when reusing this data.
