When the monitored voltage drops below this threshold, the reset output (Active Low, Push-Pull) asserts and holds for a minimum of 140ms after the supply recovers. This part belongs to the Simple Reset/Power-On Reset category within the Power Management (PMIC / Gate Driver) line. ## Industrial temp range and package The base product number is TPS3705; other threshold variants in the same family share the same pinout, so a BOM change to a different voltage option is a direct drop-in if the threshold requirement shifts.","metaTitle":"TPS3705-33DGN Texas Instruments Simple Reset/Power-On Reset","metaDescription":"TPS3705-33DGN from Texas Instruments: Active-low reset supervisor, 2.93V threshold, 140ms timeout, -40°C to 85°C, 8-MSOP exposed pad.","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":"Tube","Mounting Type":"Surface Mount","Reset Timeout":"140ms Minimum","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3705","Voltage - Threshold":"2.93V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-HVSSOP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9900","priceTiers":[{"qty":1,"price":"$2.99000","currency":"USD"},{"qty":10,"price":"$2.68400","currency":"USD"},{"qty":25,"price":"$2.53760","currency":"USD"},{"qty":100,"price":"$2.19930","currency":"USD"},{"qty":250,"price":"$2.08652","currency":"USD"},{"qty":500,"price":"$1.87222","currency":"USD"},{"qty":1000,"price":"$1.59600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/08e30cb9c14d60784f5910520df54f45.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3705-33DGN/alternatives.json"},"ai":{"faq":[{"question":"How can I order TPS3705-33DGN or check availability?","answer":"The TPS3705-33DGN is an Active Texas Instruments part. Submit an RFQ with your target quantity; we source through our distribution network and confirm current pricing and lead time at quote time. The part ships in Tube packaging."},{"question":"What is the reset timeout of TPS3705-33DGN?","answer":"The reset timeout is 140ms minimum. After the supply rises above the threshold, the reset output remains low for at least 140ms before releasing."},{"question":"What are equivalents or alternatives to TPS3705-33DGN?","answer":"Functional alternatives include the TLV803EA29VDBZR (Active Low, Open Drain, 130ms timeout, -40°C to 125°C) and TLV803ED29DBZR (Active Low, Open Drain, 33ms timeout, -40°C to 125°C). Both are from Texas Instruments but have Open Drain output instead of Push-Pull, and different timeout and temperature ranges. Verify the output type and timing requirements before substituting."},{"question":"Is TPS3705-33DGN pin compatible with TPS3705-30?","answer":"The TPS3705 family shares the same pinout across threshold variants. The TPS3705-30 would have a 3.0V threshold; the package and pin functions are identical, so it is a direct drop-in if the threshold requirement changes."},{"question":"How to use TPS3705-33DGN in a circuit?","answer":"Connect the VDD pin to the 3.3V rail being monitored. The reset output (Active Low, Push-Pull) drives the processor reset input directly without an external pull-up resistor. A 0.1µF decoupling capacitor near the VDD pin is recommended."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3705-33DGN","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3705-33DGN when reusing this data.
