The active-low, open-drain output pulls low during reset and releases when the supply rises above the threshold plus hysteresis, with a guaranteed minimum reset timeout of 65 ms to let the system power-up cleanly. ## Open-drain output and the pull-up resistor The open-drain output lets you wire-OR the reset signal with other supervisors or pull it to a different voltage level (e.g., 3.3 V) independent of the monitored rail. The base product number TPS3103 covers several threshold options in the same SOT-23-6 footprint, so if the voltage requirement shifts, a pin-compatible variant is available without a board spin.","metaTitle":"TPS3103E15DBVRG4 Simple Reset/Power-On Reset","metaDescription":"TI TPS3103E15DBVRG4 simple reset IC with active-low open-drain output, 1.434 V threshold, 65 ms min reset timeout, SOT-23-6, -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)","Mounting Type":"Surface Mount","Reset Timeout":"65ms Minimum","Package / Case":"SOT-23-6","lifecycle_stage":"eol_hot","Base Product Number":"TPS3103","Voltage - Threshold":"1.434V","Operating Temperature":"-40°C~85°C(TJ)","Supplier Device Package":"SOT-23-6","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/701739d347891bc1d0c0a11cee3634c9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3103E15DBVRG4/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3103E15DBVRG4 compatible with a 1.8 V supply?","answer":"Yes. The 1.434 V threshold is 0.366 V below the 1.8 V nominal rail, so the reset will not assert under normal conditions. The part monitors a single voltage, and the threshold is set to supervise a 1.8 V supply for undervoltage conditions."},{"question":"What is the reset timeout duration for TPS3103E15DBVRG4?","answer":"The reset timeout is 65 ms minimum — the output stays low for at least 65 ms after the supply rises above the threshold."},{"question":"Does TPS3103E15DBVRG4 have an open drain output?","answer":"Yes, the output is open drain (open collector), active low.
