This gives the core supply and oscillator time to stabilise before the processor or FPGA starts executing code. The timeout is fixed — no external capacitor needed. ## SOT-23-5 footprint, active production","metaTitle":"TPS3128E12DBVT Simple Reset/Power-On Reset, 1.14V Threshold","metaDescription":"Texas Instruments TPS3128E12DBVT simple reset/power-on reset IC with active-low open-drain output. 1.14V threshold, 100ms timeout, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"100ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3128","Voltage - Threshold":"1.14V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/33ce582e7a8405bef9aabe534ac434b3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3128E12DBVT/alternatives.json"},"ai":{"faq":[{"question":"Can TPS3128E12DBVT replace TPS3128E12DBVR?","answer":"Yes, the TPS3128E12DBVT and TPS3128E12DBVR are functionally identical — same threshold, same timeout, same open-drain output. For most designs the parts are interchangeable; the DBVT variant gives you the flexibility to order smaller quantities in cut tape."},{"question":"Is TPS3128E12DBVT compatible with 3.3V logic?","answer":"Yes. The open-drain output allows the reset signal to be pulled up to any voltage within the device's ratings, including 3.3V. Connect a pull-up resistor from the output pin to your 3.3V rail, and the reset line will swing between ground and 3.3V — no level translation needed."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3128E12DBVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3128E12DBVT when reusing this data.
