This is long enough to cover the charging time of typical bulk decoupling capacitors on a 2.5 V rail without requiring an external delay capacitor. ## Package and footprint for production The TPS3851G25EQDRBRQ1 comes in an 8-VSON package with a 3x3 mm body and an exposed thermal pad (8-VDFN Exposed Pad). The wettable flank option improves solder-joint inspection and reliability, which is especially useful for automotive assembly lines using automated optical inspection (AOI). The small footprint suits space-constrained ECU layouts.","metaTitle":"TPS3851G25EQDRBRQ1 Simple Reset/Power-On Reset IC, AEC-Q100","metaDescription":"Texas Instruments TPS3851G25EQDRBRQ1 automotive-grade simple reset IC, active-low open-drain output, 170 ms min reset timeout, 2.5 V threshold, -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":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Mounting Type":"Surface Mount, Wettable Flank","Reset Timeout":"170ms Minimum","Package / Case":"8-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3851","Voltage - Threshold":"2.5V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-VSON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1025","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5aefb0da23b9c7d55a312613af0250ba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3851G25EQDRBRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3851G25EQDRBRQ1 automotive qualified?","answer":"Yes, the TPS3851G25EQDRBRQ1 is AEC-Q100 qualified, which means it meets the stress and reliability requirements for automotive-grade components."},{"question":"What is the reset timeout of TPS3851G25EQDRBRQ1?","answer":"The reset timeout is a minimum of 170 ms.
