The SOT-23-5 package (SC-74A) keeps the footprint small enough for cramped ECU layouts, but the 0.95 mm pitch means a decent soldermask web between pads — no fine-pitch surprises for the PCB layout engineer. That means TI is not actively developing this variant, and it may move to last-time-buy without a long window. But any new BOM should look at the wider TPS382x family for a pin-compatible replacement with similar threshold and timeout options.","metaTitle":"TPS3820-50QDBVRQ1 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3820-50QDBVRQ1 is a Simple Reset/Power-On Reset IC with 4.55V threshold, active-low push-pull output, AEC-Q100 qualified, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","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":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"15ms Minimum","Package / Case":"SC-74A, SOT-753","Product Status":"Not For New Designs","lifecycle_stage":"eol_hot","Base Product Number":"TPS3820","Voltage - Threshold":"4.55V","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55b80fccb6c7a1290829640dc73eb79a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3820-50QDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3820-50QDBVRQ1 obsolete or still available?","answer":"It is not formally discontinued, but TI recommends against using it in new designs.
