Each of the two N-channel outputs delivers up to 3 A continuous, with a typical on-resistance of 85 mOhm — low enough to keep conduction losses manageable in a sealed ECU without active cooling. The load supply range spans 8 V to 18 V, covering the nominal 12 V automotive bus with headroom for load-dump transients. The switch operates without a separate Vcc supply — the gate drive is self-supplied from the load pin, simplifying the BOM by one rail. Integrated fault protection includes current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage clamping. Open-load detection is particularly useful for monitoring bulb or solenoid continuity in body-control modules — it flags a broken wire without an external sense resistor. The slew-rate controlled switching reduces EMI radiated from long harness runs, which matters when the switch drives cabling to door locks or exterior lighting. ## Package and thermal path The PG-DSO-14-40-EP package is a 14-lead SOIC with an exposed pad (3.90 mm body width). The footprint is standard for this Infineon PROFET family, so a layout that already carries a BTS50xx part will route directly.","metaTitle":"BTS5045-2EKA Infineon High-Side Switch, AEC-Q100, 85 mOhm","metaDescription":"Infineon BTS5045-2EKA dual high-side power switch, AEC-Q100 qualified, 85 mOhm Rds(on), 3 A per channel, 8-18 V load range, PG-DSO-14-40-EP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q100","Package":"Bulk","Features":"Slew Rate Controlled","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"85mOhm","Mounting Type":"Surface Mount","Package / Case":"14-SOIC (0.154\\\", 3.90mm Width) Exposed Pad","Product Status":"Active","Voltage - Load":"8V ~ 18V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature, Over Voltage","Number of Outputs":"2","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"3A","Supplier Device Package":"PG-DSO-14-40-EP","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.6400","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d27051ef10d4c8c06519363dc2ab463d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is BTS5045-2EKA AEC-Q100 qualified?","answer":"Yes, the BTS5045-2EKA is listed under the Automotive series and carries AEC-Q100 qualification, making it suitable for automotive-grade applications including under-hood and chassis domains."},{"question":"Does BTS5045-2EKA have open load detection?","answer":"Yes, open load detection is included in the fault protection set, along with current limiting, over-temperature shutdown, and over-voltage clamping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BTS5045-2EKA","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BTS5045-2EKA when reusing this data.
