No official successor is recorded on this line — the closest functional match would be a current PROFET 2G+ or PROFET+ 28 V device, but pin compatibility and footprint must be verified against the original board layout. ## 4-channel high-side switch — 19 mOhm and 5.6 A per output The BTS5441G is a four-output high-side power switch from Infineon's PROFET family, built with an N-channel MOSFET per channel. Each output is rated for a continuous 5.6 A maximum, with a typical on-resistance of 19 mOhm. The 4.5 V to 28 V load supply range covers standard automotive and industrial 12 V and 24 V rails. Protection features include current limiting (fixed), open-load detection, over-temperature shutdown, and over-voltage clamping — all integrated, so no external sense resistors or clamp diodes are needed. The 1:1 input-to-output ratio and non-inverting input type mean a logic-high on the control pin turns the corresponding output on. ## Package and temperature — PG-DSO-28, 150°C junction The junction temperature range extends to 150°C, which suits under-hood automotive or industrial enclosures where ambient heat is high. No external Vcc supply is needed — the switch is self-powered from the load rail.","metaTitle":"BTS5441G PROFET high-side switch, 4-ch 5.6A, 19 mOhm","metaDescription":"BTS5441G PROFET 4-channel high-side power switch, 5.6A max per output, 19 mOhm typ Rds(on), 4.5-28V 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":"PROFET®","Package":"Tape & Reel (TR)","Features":"-","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"19mOhm","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":"BTS5441","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"5.6A","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/7fc56eac59ab53345b940b53f993194f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the replacement for BTS5441G?","answer":"Infineon has not published a direct pin-compatible successor for the BTS5441G.
