It integrates four N-channel MOSFETs with a typical on-resistance of 45 mOhm per channel, each rated for a continuous output current up to 3.4 A. The switch operates over a load voltage range of 4.5 V to 28 V and does not require a separate Vcc supply for the logic interface — the input-to-output ratio is 1:1 with a non-inverting, parallel interface. Built-in fault protection covers current limiting (fixed), open load detection, over-temperature shutdown, and over-voltage clamping, with an auto-restart feature that re-enables the output after a fault condition clears. This makes it suitable for under-hood and engine-adjacent environments where ambient temperatures can exceed 105°C and the die must handle self-heating from continuous load current. The 45 mOhm typical Rds(on) at 25°C will increase with junction temperature — expect roughly a 50% rise at 150°C junction, which must be factored into the thermal budget for continuous 3.4 A per channel. ## Obsolete — sourcing through independent distribution The BTS5434GNT carries an Obsolete lifecycle status from Infineon. Procurement for this part is limited to surplus inventory and the independent broker channel.","metaTitle":"BTS5434GNT PROFET high-side switch, 45 mOhm, 4-ch, obsolete","metaDescription":"Infineon BTS5434GNT PROFET 4-channel high-side switch, 45 mOhm Rds(on), 3.4A per output, -40°C 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":"PROFET®","Package":"Tape & Reel (TR)","Features":"Auto Restart","Interface":"Parallel","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"45mOhm","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)":"3.4A","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/672b1452918c7c21e15f3ffeca58176b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the BTS5434GNT available via RFQ confirmation?","answer":"The BTS5434GNT is obsolete and no longer in production."},{"question":"Is the BTS5434GNT obsolete or has a replacement?","answer":"Yes, the BTS5434GNT is listed as Obsolete by Infineon.
