The open-drain stage also allows multiple supervisors to share a common reset line in a wired-OR configuration. ## Industrial temperature range and small SON package","metaTitle":"TPS3851G50SDRBR Simple Reset/Power-On Reset IC, 5V Threshold","metaDescription":"Texas Instruments TPS3851G50SDRBR simple reset/power-on reset IC with 5V threshold, 170ms min timeout, active low open-drain output. -40°C to 125°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); 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":"5V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-SON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9345","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8b12e106fffde0cd8e50687639f4b04b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3851G50SDRBR/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout and voltage threshold of TPS3851G50SDRBR?","answer":"The voltage threshold is 5V, and the reset timeout is a minimum of 170 ms.
