The slew rate is controlled by an external capacitor on the CT pin, which sets the turn-on ramp and limits inrush current into bulk capacitance on the output. The On/Off interface is non-inverting and does not require a separate Vcc supply. ## 10-WSON package — footprint and thermal path The 10-WFDFN with exposed pad (3 mm x 2 mm body) is a low-profile surface-mount package suited for dense boards.","metaTitle":"TPS22990NDMLR load switch, 3.9 mOhm, 10 A, Power Good","metaDescription":"Texas Instruments TPS22990NDMLR high-side load switch: 3.9 mOhm Rds(on), 10 A max, 2.5-5.5 V input, Power Good output, slew rate control, 10-WSON package.","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":"Power Good, Slew Rate Controlled","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"3.9mOhm","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","Voltage - Load":"2.5V ~ 5.5V","lifecycle_stage":"eol_hot","Fault Protection":"-","Number of Outputs":"1","Base Product Number":"TPS22990","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~105°C(TA)","Current - Output (Max)":"10A","Supplier Device Package":"10-WSON (3x2)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f527b0f31fd4cf73e74e9e6e8193f99d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22990NDMLR/alternatives.json"},"ai":{"faq":[{"question":"What is the on-resistance (Rds on) of TPS22990NDMLR?","answer":"The typical Rds(on) is 3.9 mOhm at the rated load voltage and 25°C junction.
