It switches a grounded load up to 28 V and 1.95 A, with a typical on-resistance of 80 mOhm — the conduction loss at 1 A is under 80 mV drop, keeping the load voltage close to the rail. Input is non-inverting with a 1:1 ratio, so a logic-high on the gate turns the output on. No external Vcc is required — the gate is driven from the load supply itself. ## Thermal and protection margins Built-in fault protection includes fixed current limiting and over-temperature shutdown. If the load draws more than the current limit or the die exceeds the thermal threshold, the switch latches off — no external sense resistor or comparator needed. ## Sourcing reality: obsolete, available through surplus","metaTitle":"IPS1041LTRPBF Low-Side Switch, 80 mOhm, 1.95 A, Obsolete","metaDescription":"IPS1041LTRPBF single-channel low-side N-channel switch, 80 mOhm typical Rds(on), 1.95 A max 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":"-","Package":"Tape & Reel (TR)","Features":"-","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"80mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-261-4, TO-261AA","Product Status":"Obsolete","Voltage - Load":"28V (Max)","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature","Number of Outputs":"1","Base Product Number":"IPS1041","Output Configuration":"Low Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"1.95A","Supplier Device Package":"SOT-223","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/486a6412a5ad70145a96b958ccf71f89.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IPS1041LTRPBF/alternatives.json"},"ai":{"faq":[{"question":"What is the typical Rds(on) of IPS1041LTRPBF?","answer":"The typical on-resistance is 80 mOhm at room temperature.
