The 170ms minimum reset timeout holds the system in reset long enough for the core supply to stabilise before the processor or FPGA boots. ## Package and footprint — 8-SON with exposed pad Surface-mount assembly; the 0.50 mm pitch is manageable on a 2-layer board if the thermal pad is stitched to the ground plane with enough vias.","metaTitle":"TPS3851H30EDRBT TI Simple Reset/Power-On Reset, 3V Threshold","metaDescription":"Texas Instruments TPS3851H30EDRBT — Simple Reset/Power-On Reset, Active Low, Open Drain output, 3V threshold, 170ms min reset timeout, -40°C to 125°C, 8-SON","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":"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":"$3.1100","priceTiers":[{"qty":1,"price":"$3.11000","currency":"USD"},{"qty":10,"price":"$2.79800","currency":"USD"},{"qty":25,"price":"$2.63920","currency":"USD"},{"qty":100,"price":"$2.24880","currency":"USD"},{"qty":250,"price":"$2.11152","currency":"USD"},{"qty":500,"price":"$1.84758","currency":"USD"},{"qty":1250,"price":"$1.53085","currency":"USD"},{"qty":2500,"price":"$1.49400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/8b12e106fffde0cd8e50687639f4b04b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3851H30EDRBT/alternatives.json"},"ai":{"faq":[{"question":"What is the reset threshold of TPS3851H30EDRBT?","answer":"The voltage threshold is 3V.
