The switch is enabled by a non-inverting On/Off interface and includes load discharge and slew rate control features. ## What the 4.4 mOhm Rds(on) and 15 A rating mean for the board The slew rate control limits inrush current into capacitive loads, which prevents upstream supply droop during power-up sequencing. ## Package and rework — 8-WSON with exposed pad It is reworkable with hot air — the pad size is small enough that a standard hot-air station can lift the part without cooking adjacent components. The 105°C ceiling covers the hot side of a ventilated enclosure; if the board sits near a heat sink or in a sealed box, the 15 A rating should be derated per the datasheet thermal curves.","metaTitle":"TPS22959DNYT load switch, 4.4 mOhm, 15 A, 8-WSON","metaDescription":"Texas Instruments TPS22959DNYT: 15 A load switch, 4.4 mOhm Rds(on), 0.8-5.5 V input, load discharge, slew rate control, 8-WSON, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Load Discharge, Slew Rate Controlled","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"4.4mOhm","Mounting Type":"Surface Mount","Package / Case":"8-WDFN Exposed Pad","Product Status":"Active","Voltage - Load":"0.8V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"-","Number of Outputs":"1","Base Product Number":"TPS22959","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~105°C(TA)","Current - Output (Max)":"15A","Supplier Device Package":"8-WSON (3x3)","Voltage - Supply (Vcc/Vdd)":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/40574d7b988b425aeedaaf917c6fc847.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22959DNYT/alternatives.json"},"ai":{"faq":[{"question":"What is the typical on-resistance of TPS22959DNYT?","answer":"The typical Rds(on) is 4.4 mOhm.
