That 170 ms window is the system's power-up hold-off — it keeps the processor in reset until the supply and oscillator have stabilised, so the first instruction fetch sees valid code. ## Thermal range and package — board fit for automotive ECUs For a multi-year automotive program, that means the part can be qualified into the BOM without scheduling a future respin.","metaTitle":"Texas Instruments TPS3851H33SQDRBRQ1 Simple Reset/Power-On","metaDescription":"Texas Instruments TPS3851H33SQDRBRQ1 automotive-grade simple reset/power-on reset, active low open drain output, 170ms min timeout, -40°C to 125°C, 8-SON (3x3)","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":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"170ms Minimum","Package / Case":"8-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3851","Voltage - Threshold":"3.3V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-SON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5aefb0da23b9c7d55a312613af0250ba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3851H33SQDRBRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3851H33SQDRBRQ1 AEC-Q100 qualified?","answer":"Yes.
