That means TI has issued a final purchase window — once that window closes, the TPS3620-50DGKT will no longer be manufactured. Any remaining stock moves through the surplus and independent distribution channel. If you have an active BOM position, secure your lifetime buy quantity now and qualify a replacement before the last order date passes. ## What the 60 ms reset timeout buys you The 60 ms minimum reset timeout is the period the part holds the processor in reset after the supply rail has returned above the threshold. That window covers the oscillator start-up, PLL lock, and internal regulator settling of most microcontrollers and FPGAs. That covers most outdoor telecom, factory automation, and automotive cabin applications. The small footprint means it fits on tight mixed-signal boards where the battery backup supervisor sits near the coin cell holder or supercapacitor.","metaTitle":"TPS3620-50DGKT Battery Backup Circuit, 4.55V Threshold","metaDescription":"TI TPS3620-50DGKT battery backup supervisor IC with 4.55V threshold, active-low reset, 60ms timeout.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","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) Cut Tape (CT)","Mounting Type":"Surface Mount","Reset Timeout":"60ms Minimum","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Last Time Buy","lifecycle_stage":"eol_hot","Base Product Number":"TPS3620","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":"$4.2000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ae93676fcfae3cff35626cc09a4a46ae.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS3620-50DGKT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS3620-50DGKT obsolete?","answer":"It is not yet obsolete, but it is in Last Buy status.
