The open-drain output can be pulled up to any logic voltage up to the absolute maximum rating of the output transistor."},{"question":"What is the reset timeout for TPS3850G18DRCR?","answer":"The reset timeout is adjustable or selectable via an external capacitor or pin-strapping, depending on the specific variant within the TPS3850 family. The exact timing range is defined in the device datasheet."},{"question":"How does TPS3850G18DRCR compare with TPS3850G20?","answer":"The TPS3850G18DRCR monitors a 1.8V threshold, while the TPS3850G20 monitors a 2.0V threshold. Both are in the same TPS3850 family with the same package and temperature range; the choice is driven by the supply voltage you need to supervise."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3850G18DRCR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3850G18DRCR when reusing this data.
