It is the part you reach for when a microcontroller, FPGA, or SoC needs a clean, glitch-free reset during power-up or a brownout event. The reset output is Active Low and open-drain, so it can be wire-ORed with other reset sources or pulled up to a different voltage than the monitored rail. The reset timeout is adjustable with an external capacitor, giving you control over how long the processor stays in reset after the supply stabilises. ## Package and temperature range for the application The 8-VDFN exposed pad package (Supplier Device Package 8-SON) is a surface-mount footprint with a 3x3 mm body. ## Sourcing posture and lifecycle Because the lifecycle is active, you can order this part against a BOM line without worrying about a looming obsolescence.","metaTitle":"TPS3852H33DRBT – TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3852H33DRBT: Active Low, Open Drain output, 3.3V threshold, -40°C to 125°C, 8-SON (3x3) package.","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":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"Adjustable/Selectable","Package / Case":"8-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3852","Voltage - Threshold":"3.3V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-SON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.0100","priceTiers":[{"qty":1,"price":"$3.01000","currency":"USD"},{"qty":10,"price":"$2.70700","currency":"USD"},{"qty":25,"price":"$2.55880","currency":"USD"},{"qty":100,"price":"$2.21760","currency":"USD"},{"qty":250,"price":"$2.10388","currency":"USD"},{"qty":500,"price":"$1.88780","currency":"USD"},{"qty":1250,"price":"$1.60929","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/78e26620fa76d5587836e3f45f470c90.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3852H33DRBT/alternatives.json"},"ai":{"faq":[{"question":"Can TPS3852H33DRBT replace TPS3852H33 in an existing design?","answer":"The TPS3852H33DRBT shares the same base product number TPS3852 and the same 3.3V threshold. The 'DRBT' suffix indicates the 8-SON (3x3) package and Tape & Reel packaging. If the original TPS3852H33 was in a different package, confirm the footprint compatibility before substituting. The electrical specifications for the 3.3V threshold and reset behaviour are identical across the family."},{"question":"Is TPS3852H33DRBT compatible with a push-pull reset output?","answer":"No — the TPS3852H33DRBT has an open-drain output, not push-pull. An open-drain output requires an external pull-up resistor to the desired reset voltage rail. If your design expects a push-pull output, you would need a different supervisor or add a pull-up resistor and accept the logic-level translation."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3852H33DRBT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3852H33DRBT when reusing this data.
