Its 150 mOhm typical Rds(on) and 1.8 A continuous output rating suit it for driving resistive, inductive, and capacitive loads like relays, solenoids, lamps, and small motors on 12 V or 24 V board nets. The load supply range spans 6 V to 52 V, covering nominal 12 V and 24 V systems with headroom for load-dump transients up to 52 V. No external Vcc supply is needed — the switch is self-powered from the load rail. ## On-resistance and thermal budget under continuous 1.8 A At 1.8 A continuous, the 150 mOhm Rds(on) typ produces a voltage drop of 0.27 V and dissipates roughly 0.49 W in the die. The switch integrates fixed current limiting, over-temperature shutdown, and over-voltage protection. Auto-restart after a fault cycle is enabled by the feature set — the part attempts to re-close after a cool-down period, which is useful for transient overloads like lamp inrush. Infineon lists the BTS452TATMA1 as Active. The part is ROHS3 compliant. For a production BOM that cannot tolerate a sudden stop, this status means you can commit the line without a lifecycle watch item.","metaTitle":"BTS452TATMA1 Infineon miniPROFET High-Side Switch, 150 mOhm","metaDescription":"BTS452TATMA1 automotive high-side power switch from Infineon miniPROFET series.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100, miniPROFET®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"Automotive, AEC-Q100, miniPROFET®","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"Auto Restart","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"150mOhm","Mounting Type":"Surface Mount","Package / Case":"TO-252-5, DPak (4 Leads + Tab), TO-252AD","Product Status":"Active","Voltage - Load":"6V ~ 52V","lifecycle_stage":"eol_hot","Fault Protection":"Current Limiting (Fixed), Over Temperature, Over Voltage","Number of Outputs":"1","Base Product Number":"BTS452","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C ~ 150°C (TJ)","Current - Output (Max)":"1.8A","Supplier Device Package":"PG-TO252-5","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3700","priceTiers":[{"qty":1,"price":"$2.37000","currency":"USD"},{"qty":10,"price":"$2.12800","currency":"USD"},{"qty":25,"price":"$2.00760","currency":"USD"},{"qty":100,"price":"$1.71030","currency":"USD"},{"qty":250,"price":"$1.60592","currency":"USD"},{"qty":500,"price":"$1.40518","currency":"USD"},{"qty":1000,"price":"$1.16429","currency":"USD"},{"qty":2500,"price":"$1.08400","currency":"USD"},{"qty":5000,"price":"$1.04385","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/f6420c3753e7899d6a54b20eafa80e08.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BTS452TATMA1/alternatives.json"},"ai":{"faq":[{"question":"How does BTS452TATMA1 compare to BTS142DATMA1?","answer":"The BTS142DATMA1 is a low-side switch (BTS452 is high-side) from Infineon's HITFET series, with a 23 mOhm Rds(on) and 4.6 A output, but it operates at a lower 42 V max load voltage.
