When a fault condition clears, the auto-restart feature re-enables the output without external intervention — a useful behaviour for remote or sealed assemblies where manual reset is impractical. The input is non-inverting with a simple On/Off interface, and the output configuration is high-side with a 1:1 input-to-output ratio. Buyers should validate pin-compatibility and electrical ratings against any proposed substitute before committing the BOM line.","metaTitle":"IPS5451STRL High-Side Switch, 19 mOhm, 3.5 A, D²Pak-5","metaDescription":"IPS5451STRL is an obsolete 3.5 A high-side N-channel switch with 19 mOhm Rds(on), integrated fault protection, and -40 to 150 °C 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":"-","Package":"Tape & Reel (TR)","Features":"Auto Restart","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":"TO-263-5, D²Pak (4 Leads + Tab), TO-263BB","Product Status":"Obsolete","Voltage - Load":"5.5V ~ 18V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Open Load Detect, Over Temperature","Number of Outputs":"1","Base Product Number":"IPS5451","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"3.5A","Supplier Device Package":"D2Pak (SMD-220 5-Lead)","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/a06ca89ca70bc764d6aca042eed932e5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IPS5451STRL/alternatives.json"},"ai":{"faq":[{"question":"Does IPS5451STRL have overcurrent protection?","answer":"Yes, the IPS5451STRL includes fixed current limiting as part of its integrated fault protection, along with open-load detection and over-temperature shutdown."},{"question":"What is the Rds(on) of IPS5451STRL?","answer":"The typical on-resistance is 19 mOhm.
