The open-drain output lets you pull the reset line to any logic voltage up to the absolute maximum of the pin, which is handy when the supervisor runs off a different rail than the monitored core. Reset timeout is a minimum of 170ms after the supply recovers, giving the downstream device time to stabilize before release. ## Junction temperature range and package ## Active production status – no obsolescence pressure ROHS3 compliant.","metaTitle":"TPS3851G18SDRBT – TI Simple Reset/Power-On Reset","metaDescription":"Texas Instruments TPS3851G18SDRBT – Simple Reset/Power-On Reset supervisor, 1.8V threshold, Active Low open-drain output, 170ms min timeout, -40°C to 125°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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":"1.8V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-SON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3400","priceTiers":[{"qty":1,"price":"$2.34000","currency":"USD"},{"qty":10,"price":"$2.09800","currency":"USD"},{"qty":25,"price":"$1.97960","currency":"USD"},{"qty":100,"price":"$1.68660","currency":"USD"},{"qty":250,"price":"$1.58364","currency":"USD"},{"qty":500,"price":"$1.38568","currency":"USD"},{"qty":1250,"price":"$1.14814","currency":"USD"},{"qty":2500,"price":"$1.12050","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8b12e106fffde0cd8e50687639f4b04b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3851G18SDRBT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TPS3851G18SDRBT and check current pricing?","answer":"The TPS3851G18SDRBT is an active-production Texas Instruments part. We source it through our distribution network — submit an RFQ with your target quantity and we will confirm availability and pricing for your BOM line. No stock-holding claim is made here; every order is quoted to your specific needs."},{"question":"Can TPS3851G18SDRBT work with a 3.3V supply?","answer":"The device monitors a single 1.8V rail. The open-drain output can be pulled up to a voltage higher than 1.8V, but the monitored threshold is fixed at 1.8V — it will not assert reset if a 3.3V rail drops unless that rail is divided down to 1.8V and fed to the sense input. For 3.3V monitoring, choose a variant with a 3.3V threshold."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS3851G18SDRBT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS3851G18SDRBT when reusing this data.
