Each output is rated for a continuous 5.7 A maximum, and the typical on-resistance of 21 mOhm keeps conduction losses low enough that the 28-SOIC package can dissipate the heat without forced airflow in most 12 V and 24 V loads. ## Load voltage and protection — where it fits the BOM The load supply range spans 4.5 V to 28 V, covering standard automotive and industrial rails but not 3.3 V logic-level loads. Integrated fault protection includes current limiting (fixed threshold), open-load detection, overtemperature shutdown, and overvoltage clamp — four diagnostics that reduce the need for external sense resistors or comparators on each channel. ## Obsolete — sourcing strategy for the BOM line Infineon lists the BTS5440GXUMA1 as obsolete.","metaTitle":"BTS5440GXUMA1 Infineon IntelliSense™ High-Side Switch","metaDescription":"Infineon BTS5440GXUMA1 4-channel high-side power switch, 21 mOhm typical Rds(on), 5.7 A per channel, 4.5-28 V load range, -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","Base Product Number":"BTS5440","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 BTS5440GXUMA1 obsolete?","answer":"Yes, Infineon has classified the BTS5440GXUMA1 as obsolete.
