The reset outputs are available as both active-high and active-low signals, with a push-pull, totem-pole stage that drives CMOS logic inputs directly without an external pull-up. The minimum reset timeout of 140 ms ensures the downstream processor or FPGA holds reset long enough for all rails to stabilise after power-up. ## Industrial temperature rating and package fit Surface-mount assembly with the SOIC-8 body simplifies pick-and-place — no through-hole steps, no manual insertion. The 1.27 mm pin pitch is inspectable and reworkable with basic hot-air tools. It can be specified into a production BOM without near-term obsolescence risk. The base product number TPS3307 covers the family, and the -33DG4 suffix identifies the specific threshold variant and package.

The -33DG4 suffix indicates a specific factory-programmed threshold variant (2.93V, 4.55V, and adjustable third rail) in the 8-SOIC package. The -33D variant may differ in threshold voltages or packaging options — confirm the exact threshold set against your BOM requirements."},{"question":"What does the adjustable third threshold mean for my design?","answer":"The third monitored voltage is set by an external resistor divider, so you can supervise a non-standard rail (e.g., 1.8V, 3.0V, or 5.0V) that does not match the two fixed thresholds. This flexibility reduces the number of supervisor ICs needed on a multi-rail board."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3307-33DG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3307-33DG4 when reusing this data.
