The open-drain output lets you wire-OR it with other reset signals, but you need an external pull-up resistor to the logic supply. ## 8-SON package and footprint Housed in an 8-SON (3x3 mm) exposed-pad package, the TPS3851H25SQDRBRQ1 is a surface-mount device. The 3x3 mm footprint is compact enough for space-constrained automotive ECU layouts, but the pad pitch is fine enough that a two-layer board may struggle with fan-out; a four-layer stack with a dedicated ground plane under the pad is the safer call.","metaTitle":"TI TPS3851H25SQDRBRQ1 Simple Reset/Power-On Reset, AEC-Q100","metaDescription":"Texas Instruments TPS3851H25SQDRBRQ1 automotive simple reset IC, monitors 2.5V rail, active-low open-drain output, 170ms min timeout, -40°C to 125°C, 8-SON.","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":"2.5V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-SON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1025","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/5aefb0da23b9c7d55a312613af0250ba.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3851H25SQDRBRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3851H25SQDRBRQ1?","answer":"The reset timeout is 170ms minimum. After the monitored 2.5V rail rises above the threshold, the reset output stays low for at least 170ms before releasing.
