Each output delivers up to 5.7 A continuous, with a typical on-resistance of 21 mOhm. At 5.7 A per channel, the conduction loss is I²R = 0.68 W per channel, or 2.7 W if all four channels are on simultaneously. The PG-DSO-28-19 package (a 28-pin SOIC wide-body, 7.50 mm width) dissipates that through the copper pad on the PCB — a 2 oz copper pour under the package is the practical heatsink. The 150°C junction rating gives headroom for high ambient temperatures common in engine bay or industrial cabinet environments. ## Fault protection that reduces external BOM The over-voltage clamp handles transients up to the 28 V load supply maximum. Infineon lists the BTS5440GNT as obsolete.","metaTitle":"Infineon BTS5440GNT IntelliSense high-side switch, 21 mOhm","metaDescription":"Infineon BTS5440GNT IntelliSense quad high-side N-channel switch, 21 mOhm Rds(on), 5.7 A per channel, 4.5-28 V load, -40 to 150°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"IntelliSense™","Package":"Tape & Reel (TR)","Features":"-","Interface":"Parallel","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"21mOhm","Mounting Type":"Surface Mount","Package / Case":"28-SOIC (0.295\\\", 7.50mm Width)","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":"4","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"5.7A","Supplier Device Package":"PG-DSO-28-19","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2b6af1dbfe66b10a0d712e7f3ee5df07.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is the BTS5440GNT obsolete?","answer":"Yes, Infineon lists the BTS5440GNT as obsolete.
