The open-drain output can be pulled up to a different voltage rail, making it straightforward to interface with 1.8V or 5V logic domains. Surface-mount assembly with a standard reflow profile handles the VDFN package.","metaTitle":"TPS3852H33DRBR Simple Reset/Power-On Reset, 3.3V Threshold","metaDescription":"Texas Instruments TPS3852H33DRBR is a simple reset/power-on reset IC with 3.3V threshold, active-low open-drain output, adjustable timeout, -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":"Adjustable/Selectable","Package / Case":"8-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3852","Voltage - Threshold":"3.3V","Operating Temperature":"-40°C~125°C(TJ)","Supplier Device Package":"8-SON (3x3)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0065","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/78e26620fa76d5587836e3f45f470c90.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3852H33DRBR/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3852H33DRBR?","answer":"The reset timeout is adjustable and selectable via an external capacitor.
