It handles a load voltage from 2.8 V to 19.8 V, covering the Thunderbolt power-rail range plus general-purpose 5 V, 12 V, and 19 V supplies in notebooks, docking stations, and peripheral hubs. The switch integrates reverse-current fault protection, which blocks back-feed when the output voltage exceeds the input — critical in hot-plug and multi-rail systems where a downstream capacitor can hold the rail high during a source brownout. ## Two internal switches — why the dual Rds(on) matters The part lists two Rds(on) maximums: 5 Ohm and 250 mOhm. This indicates one switch is sized for low-current signal or auxiliary rails (5 Ohm path), while the other handles the main power delivery (250 mOhm path). The 250 mOhm switch passes several amps at 19.8 V with manageable conduction loss; the 5 Ohm switch suits sub-100 mA loads where inrush limiting or fault isolation is the priority. ## NRND — plan your BOM transition That means TI is not accepting new-design-in activity; existing production runs may continue, but the part is on a path toward end-of-life. For a new BOM, look at the current Thunderbolt switch family — the TPS22986 or TPS22988 series offers similar dual-output high-side switching with active lifecycle support. ## 16-DSBGA — layout and assembly notes The 16-DSBGA package measures 1.6 mm x 1.6 mm with a 0.4 mm ball pitch. The small footprint and fine pitch demand a controlled-impedance PCB stack-up with micro-via fan-out under the BGA.","metaTitle":"TPS22985YFPR Thunderbolt™ Load Switch, NRND, 2.8V–19.8V","metaDescription":"Texas Instruments TPS22985YFPR Thunderbolt™ series high-side load switch. 2 outputs, 5 Ohm / 250 mOhm Rds(on), 2.8V–19.8V load, 16-DSBGA.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Thunderbolt™","Package":"Tape & Reel (TR)","Features":"-","Interface":"-","Input Type":"-","Output Type":"-","Switch Type":"General Purpose","Rds On (Typ)":"5Ohm (Max), 250mOhm (Max)","Mounting Type":"Surface Mount","Package / Case":"16-XFBGA, DSBGA","Product Status":"Not For New Designs","Voltage - Load":"2.8V ~ 19.8V","lifecycle_stage":"eol_hot","Fault Protection":"Reverse Current","Number of Outputs":"2","Base Product Number":"TPS22985","Output Configuration":"High Side","Ratio - Input:Output":"1:2","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"-","Supplier Device Package":"16-DSBGA (1.6x1.6)","Voltage - Supply (Vcc/Vdd)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5180","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9bcb2934a7655abaea7e358b6bd66451.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22985YFPR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS22985YFPR obsolete?","answer":"TI still supports existing designs, but the part is on a path toward end-of-life.
