The open-drain output lets you wire-OR multiple reset signals or pull it up to a different voltage than the monitored rail. ## 65ms reset timeout — why it matters for the BOM If the timeout were shorter — say 20ms — a slow-ramping 1.2V rail could release reset before the regulator has reached its final voltage, causing brown-out or undefined boot behaviour. For designs running a 1.2V core supply from a small LDO or a switching regulator with soft-start, this 65ms window is the safety margin that prevents field failures. ## Industrial temperature range and SOT-23-6 footprint The SOT-23-6 package occupies about 3 mm² of board area, which keeps the routing short between the supervisor and the monitored rail. The 0.95 mm pin pitch is standard for a 6-pin SOT-23; the open-drain output connects directly to the processor's reset input with a single pull-up resistor. ## Obsolete — how to source it now No official successor part is listed on the record.","metaTitle":"TPS3103E12DBVRG4 Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3103E12DBVRG4 simple reset IC, active-low open-drain output, 65ms min timeout, 1.142V threshold, -40°C to 85°C, SOT-23-6.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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)","Mounting Type":"Surface Mount","Reset Timeout":"65ms Minimum","Package / Case":"SOT-23-6","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"TPS3103","Voltage - Threshold":"1.142V","Operating Temperature":"-40°C ~ 85°C (TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/701739d347891bc1d0c0a11cee3634c9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3103E12DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3103E12DBVRG4?","answer":"The reset timeout is a minimum of 65ms.
