The push-pull output drives the reset line directly without an external pull-up resistor, saving one component per rail. ## Package and footprint: 4-X2SON with exposed pad Housed in a 4-X2SON package measuring 1x1 mm, the TPS3839K33DQNT fits into space-constrained designs such as sensor modules, wearables, and compact IoT nodes. The small body means the part is sensitive to solder-paste volume; a stencil aperture matching the pad dimensions prevents tombstoning. The part is ROHS3 compliant.","metaTitle":"TPS3839K33DQNT TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3839K33DQNT: Simple Reset/Power-On Reset IC, 2.93V threshold, active-low push-pull output, 120ms timeout, 4-X2SON (1x1 mm), -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Simple Reset/Power-On Reset","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"4-XDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3839","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"4-X2SON (1x1)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2300","priceTiers":[{"qty":1,"price":"$1.23000","currency":"USD"},{"qty":10,"price":"$1.10100","currency":"USD"},{"qty":25,"price":"$1.04480","currency":"USD"},{"qty":100,"price":"$0.85820","currency":"USD"},{"qty":250,"price":"$0.60164","currency":"USD"},{"qty":500,"price":"$0.53170","currency":"USD"},{"qty":1250,"price":"$0.41976","currency":"USD"},{"qty":2500,"price":"$0.39600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8db2a3e3b3bb51ea8ca211210c7cfea5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3839K33DQNT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3839K33DQNT obsolete?","answer":"No. Texas Instruments lists the product status as Active.

The TPS3839K33DQNT's push-pull output saves the pull-up resistor. Both are active and share the same package family, but the output driver difference affects the BOM."},{"question":"Is TPS3839K33DQNT RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3839K33DQNT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3839K33DQNT when reusing this data.
