For a 200 MHz-class MCU or a modest FPGA, 100 ms is generous; for a fast-booting application processor, check whether the timeout delays the system power-on sequence beyond the spec. ## Push-pull output with dual polarity assertion The output stage is push-pull, totem-pole, and asserts both active-high and active-low reset signals. That means a single TPS3125G15DBVTG4 can drive the /RESET input of an MCU that expects a low-true signal and simultaneously drive a high-true enable on a downstream regulator or a status LED. No external pull-up resistor is needed on either output — the push-pull stage sources and sinks current directly. The SOT-23-5 package (SC-74A) is a standard 5-pin footprint shared across many TI supervisor ICs — the board layout can be reused if a different threshold voltage is needed later.","metaTitle":"TPS3125G15DBVTG4 Simple Reset/Power-On Reset, 1.4V Threshold","metaDescription":"Texas Instruments TPS3125G15DBVTG4 simple reset IC, 1.4V threshold, 100ms min timeout, push-pull output, -40°C to 85°C, SOT-23-5.","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 High/Active Low","Output":"Push-Pull, Totem Pole","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Reset Timeout":"100ms Minimum","Package / Case":"SC-74A, SOT-753","lifecycle_stage":"eol_hot","Base Product Number":"TPS3125","Voltage - Threshold":"1.4V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-5","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/33ce582e7a8405bef9aabe534ac434b3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3125G15DBVTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3125G15DBVTG4?","answer":"The reset timeout is a minimum of 100 ms.
