The current-limit threshold is set with an external resistor, so you can tailor the trip point to the downstream load without changing the switch itself. The open-drain status flag asserts when the switch is in current-limit or thermal-shutdown — a direct input to a GPIO or a fault-logic gate. ## Package and thermal: 10-VSON exposed pad The part comes in a 10-VFDFN exposed-pad package (supplier device package 10-VSON, 3 mm x 3 mm). The 0.50 mm pitch on the signal pads is manageable with a standard two-layer board if the fan-out is planned, but a four-layer stack with a dedicated thermal plane under the pad is the safer choice for continuous 5.5 A operation at 125°C junction temperature. The base product number is TPS2559, so if a different package variant or current rating is needed later, the family shares the same pinout and protection architecture.","metaTitle":"TPS2559QWDRCRQ1 Automotive High-Side Power Switch, 13 mOhm","metaDescription":"Texas Instruments TPS2559QWDRCRQ1, AEC-Q100 high-side power switch, 5.5 A output, 13 mOhm Rds(on), 2.5 V to 6.5 V load, adjustable current limit, -40°C to","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Features":"Slew Rate Controlled, Status Flag","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"13mOhm","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Active","Voltage - Load":"2.5V ~ 6.5V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Adjustable), Over Temperature, Reverse Current, UVLO","Number of Outputs":"1","Base Product Number":"TPS2559","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~125°C(TJ)","Current - Output (Max)":"5.5A","Supplier Device Package":"10-VSON (3x3)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3d3c35e8b7a29d9bd6d69e1277cc5f32.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS2559QWDRCRQ1/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS2559QWDRCRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS2559QWDRCRQ1 when reusing this data.
