After the supply rises above the threshold, the output holds reset low for at least 60 ms, giving the oscillator and PLL time to stabilise before the core fetches its first instruction.","metaTitle":"TPS3619-50DGKRG4 Battery Backup Circuit, 4.55V Threshold","metaDescription":"Texas Instruments TPS3619-50DGKRG4 battery backup circuit with 4.55V reset threshold, active-low push-pull output, 60ms timeout, -40°C to 85°C, 8-VSSOP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Type":"Battery Backup Circuit","Reset":"Active Low","Output":"Push-Pull, Totem Pole","Series":"-","Package":"Tape & Reel (TR)","Mounting Type":"Surface Mount","Reset Timeout":"60ms Minimum","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Base Product Number":"TPS3619","Voltage - Threshold":"4.55V","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"8-VSSOP","Number of Voltages Monitored":"1"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ae93676fcfae3cff35626cc09a4a46ae.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3619-50DGKRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the exact reset threshold voltage of TPS3619-50DGKRG4?","answer":"The reset threshold is 4.55 V.
