The typical on-resistance of 21 mOhm keeps conduction losses low enough that at 5A per channel the dissipation stays under 0.5W — manageable on the exposed pad with reasonable copper area. ## 4.5V to 28V load voltage — 12V and 24V systems covered The load voltage range spans 4.5V to 28V, which covers both 12V automotive and 24V industrial truck/bus rails without a separate regulator. No Vcc supply is required — the switch is self-powered from the load pin, simplifying the BOM by one rail. ## Fault protection set reduces external circuitry Built-in fixed current limiting, open-load detection, over-temperature shutdown, and over-voltage clamping cover the common failure modes for a resistive or inductive load. The open-load detect is useful for lamp or solenoid diagnostics — it flags a broken wire without a separate sense resistor. ## Junction temperature rated to 150°C The 150°C TJ max means the thermal shutdown threshold sits above the normal operating ceiling, giving margin for transient overloads. ## Obsolete — sourced through independent distribution The BTS5240LNT carries an Obsolete lifecycle status from Infineon.","metaTitle":"BTS5240LNT High-Side Power Switch, 5.5A, 21mOhm, Obsolete","metaDescription":"Infineon BTS5240LNT dual high-side power switch, 5.5A per channel, 21mOhm Rds(on), 4.5V-28V load range.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Features":"-","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"21mOhm","Mounting Type":"Surface Mount","Package / Case":"12-BSOP (0.295\\\", 7.50mm Width) Exposed Pad","Product Status":"Obsolete","Voltage - Load":"4.5V ~ 28V","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)":"5.5A","Supplier Device Package":"PG-DSO-12-2","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/553e5753e00792a95a240852fe945590.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the Rds(on) of the BTS5240LNT?","answer":"The typical Rds(on) is 21 mOhm per channel.
