It asserts an active-low, open-drain reset output when the monitored voltage drops below the threshold, and holds reset for 619 ms typical after the rail recovers. The 619 ms reset timeout gives downstream ICs (MCUs, FPGAs, SoCs) enough time to stabilize before the system releases from reset — critical for reliable power-up sequencing in battery-powered or noise-sensitive designs. ## Industrial temperature range and nanopower operation The nanopower architecture keeps quiescent current low, making it a fit for always-on battery-powered systems where every microamp counts. ## 6-WSON package and surface-mount assembly Housed in a 6-WSON (1.5x1.5) package, the device requires a small PCB footprint — the 0.50 mm pitch and exposed pad demand careful solder-paste stencil design and a thermal pad on the PCB for heat sinking.","metaTitle":"TPS3899DL14DSER – Texas Instruments Voltage Supervisor","metaDescription":"TPS3899DL14DSER voltage monitor from Texas Instruments, 1.4V threshold, 619 ms reset timeout, open-drain output, -40°C to 125°C, 6-WSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Monitor","Reset":"Active Low","Output":"Open Drain or Open Collector","Series":"-","Package":"Tape & Reel (TR) Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"619ms Typical","Package / Case":"6-WFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3899","Voltage - Threshold":"1.4V","Operating Temperature":"-40°C ~ 125°C (TA)","Supplier Device Package":"6-WSON (1.5x1.5)","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5400","priceTiers":[{"qty":1,"price":"$1.54000","currency":"USD"},{"qty":10,"price":"$1.37700","currency":"USD"},{"qty":25,"price":"$1.30640","currency":"USD"},{"qty":100,"price":"$1.07320","currency":"USD"},{"qty":250,"price":"$1.00324","currency":"USD"},{"qty":500,"price":"$0.88658","currency":"USD"},{"qty":1000,"price":"$0.69993","currency":"USD"},{"qty":3000,"price":"$0.56277","currency":"USD"},{"qty":6000,"price":"$0.53463","currency":"USD"},{"qty":15000,"price":"$0.51453","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0f049012f0bb7f40ae959ae09941c01c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3899DL14DSER/alternatives.json"},"ai":{"faq":[{"question":"What is the reset timeout of TPS3899DL14DSER?","answer":"The reset timeout is 619 ms typical.
