Each of the four N-channel MOSFET outputs handles up to 1.2 A continuous from a 1 V to 3.6 V load supply rail. The typical on-resistance of 15 mOhm and maximum current of 1.2 A are specified in the datasheet. The part includes a load-discharge feature that pulls the output to ground when the switch is off, and a slew-rate-controlled turn-on to limit inrush current into capacitive loads. ## Obsolete — planning the last buy or the replacement path A cross-reference requires a full datasheet review. ## Package, footprint, and the 20-WQFN assembly checklist Stencil aperture for the pad should be segmented to avoid solder voids. No AEC-Q automotive qualification is listed. Mounting is surface-mount only.","metaTitle":"TI TPS22993PRLWR load switch, 4-ch 1.2A, 15mOhm, obsolete","metaDescription":"Texas Instruments TPS22993PRLWR 4-channel I²C-controlled load switch, 1.2A per channel, 15mOhm Rds(on), 20-WQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Features":"Load Discharge, Slew Rate Controlled","Interface":"I²C","Input Type":"-","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"15mOhm","Mounting Type":"Surface Mount","Package / Case":"20-WFQFN","Product Status":"Obsolete","Voltage - Load":"1V ~ 3.6V","lifecycle_stage":"eol_hot","Fault Protection":"-","Number of Outputs":"4","Base Product Number":"TPS229","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~85°C(TA)","Current - Output (Max)":"1.2A","Supplier Device Package":"20-WQFN (3x3)","Voltage - Supply (Vcc/Vdd)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3c03467f94fa5d30552084a90a23027e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22993PRLWR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS22993PRLWR obsolete?","answer":"Yes, the product status is listed as Obsolete.
