At 10 A continuous output, that translates to under 0.4 W conduction loss at 25°C — the thermal budget stays low enough that the 10-WSON package with exposed pad can handle it without forced airflow in most industrial enclosures. That simplifies the BOM: no external charge-pump or bootstrap components. ## Power Good and slew-rate control — sequencing without a supervisor The integrated Power Good output asserts when the switch output rises above a threshold, giving the downstream load a valid-rail indicator. The slew-rate control limits inrush current during turn-on, which matters when the load includes large decoupling caps or a hot-plug card that could otherwise droop the upstream rail. ## Package and footprint — what the 10-WSON needs The datasheet layout note calls for a 2.2 mm x 1.5 mm copper pad under the package, connected to the GND plane with at least four vias. Without that thermal relief, the 10 A rating derates significantly above 85°C ambient.","metaTitle":"TPS22990NDMLT Load Switch, 3.9 mOhm, 10 A, 10-WSON","metaDescription":"Texas Instruments TPS22990NDMLT high-side load switch. 3.9 mOhm Rds(on), 10 A max, 2.5 V to 5.5 V, Power Good.","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":"$1.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f527b0f31fd4cf73e74e9e6e8193f99d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS22990NDMLT/alternatives.json"},"ai":{"faq":[{"question":"What is the Rds(on) of the TPS22990NDMLT?","answer":"The typical on-resistance is 3.9 mOhm.
