This means the reset line is driven low when the monitored voltage drops below 2.93V, and it is actively driven high (not floating) when the supply is valid. No external pull-up resistor is needed."},{"question":"What is the closest functional second-source to TPS3809K33DBVT?","answer":"The TLV803EA29VDBZR is a close functional peer — it also monitors a single voltage with active-low reset, but its output is open-drain (not push-pull), its reset timeout is 130ms minimum, and it operates up to 125°C. If your design requires a push-pull output, the TPS3809K33DBVT is the correct choice."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3809K33DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3809K33DBVT when reusing this data.
