Common in multi-rail FPGAs, SoCs, and industrial controllers that need a known start-up sequence."},{"question":"Can TPS3307-18DGN monitor 5V and 3.3V rails?","answer":"Yes, but not directly with the fixed thresholds. The 1.68V threshold can monitor a 1.8V rail, and the 2.93V threshold monitors a 3.3V rail. For a 5V rail, use the adjustable input with a resistor divider to scale 5V down to the internal reference. The supervisor itself does not have a 5V-rated sense input."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3307-18DGN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3307-18DGN when reusing this data.
