The active-low, open-drain output allows wired-OR connection with other reset sources. The 40µs typical reset timeout is short enough to avoid delaying system startup but long enough to debounce supply transients. ## Industrial temperature range and small footprint The 6-WSON package (1.5x1.5 mm) occupies minimal board area and is compatible with standard surface-mount assembly processes. ## Active production status and sourcing posture","metaTitle":"TPS3899DL28DSER Voltage Monitor – 2.8V Threshold, Active Low","metaDescription":"Texas Instruments TPS3899DL28DSER Monitor IC, 2.8V threshold, active-low open-drain output, 40µs reset timeout, -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":"40µs Typical","Package / Case":"6-WFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Base Product Number":"TPS3899","Voltage - Threshold":"2.8V","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":"$1.3300","priceTiers":[{"qty":1,"price":"$1.33000","currency":"USD"},{"qty":10,"price":"$1.18600","currency":"USD"},{"qty":25,"price":"$1.12560","currency":"USD"},{"qty":100,"price":"$0.92460","currency":"USD"},{"qty":250,"price":"$0.86424","currency":"USD"},{"qty":500,"price":"$0.76376","currency":"USD"},{"qty":1000,"price":"$0.60297","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/TPS3899DL28DSER/alternatives.json"},"ai":{"faq":[{"question":"Can TPS3899DL28DSER monitor multiple voltages?","answer":"No. The TPS3899DL28DSER monitors a single voltage rail.
