The reset output is active-low, push-pull, totem-pole, so it drives the reset line directly without needing an external pull-up. ## 120 ms reset timeout — enough for the supply to settle That is long enough for most switching supplies and linear regulators to come up cleanly after a power-on or a brown-out event, but short enough that the system does not sit idle waiting for the reset to de-assert. ## SOT-23-3 package — can I swap it on site? No hot-air station required, no paste stencil. If you have a steady hand and a decent pair of tweezers, you can swap this on a customer site without a lab bench. The three pins are clearly spaced — orientation is obvious from the pin 1 marker on the top of the package. ## Temperature range — industrial, not automotive That covers factory-floor automation, outdoor telecom cabinets, and most industrial control panels. It does not cover under-hood automotive or downhole drilling — those need the -40 to 125°C extended range parts. If your BOM calls for AEC-Q100, this is not the one. ## Lifecycle and sourcing — still in active production No last-time-buy notice, no end-of-life warning.","metaTitle":"TI TPS3839G25DBZT Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3839G25DBZT simple reset/power-on reset IC, active-low push-pull output, 2.325 V threshold, 120 ms min timeout, SOT-23-3, -40 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":"Push-Pull, Totem Pole","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"120ms Minimum","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3839","Voltage - Threshold":"2.325V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8db2a3e3b3bb51ea8ca211210c7cfea5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3839G25DBZT/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3839G25DBZT?","answer":"The reset timeout is a minimum of 120 ms.
