Each output delivers up to 5.5 A continuous, with a typical on-resistance of 21 mOhm to keep conduction losses low in power distribution and relay-replacement applications. The On/Off interface with non-inverting input simplifies microcontroller connection: a logic high turns the output on. ## 5.5 A per channel with 21 mOhm Rds(on) Each of the two N-channel outputs is rated for a continuous 5.5 A maximum, with the 21 mOhm typical Rds(on) setting the conduction-loss floor. The load supply range from 4.5 V to 28 V covers nominal 5 V, 12 V, and 24 V rails, making the part usable in automotive body controllers, industrial PLC output stages, and general-purpose power distribution. The 1:1 input-to-output ratio means each input controls one channel independently. ## Fault protection set reduces external circuitry Integrated fault protection includes fixed current limiting, open-load detection, over-temperature shutdown, and over-voltage clamping. These protections eliminate the need for external current-sense resistors, comparators, or TVS diodes in many designs — the switch handles short-circuit and thermal events autonomously. The wide temperature range, combined with the protection suite, suits applications where the switch must survive load dumps and stalled motors without external supervision. The BTS5240LAUMA1 is listed as Obsolete by Infineon.","metaTitle":"BTS5240LAUMA1 Infineon PROFET High-Side Switch, 5.5A","metaDescription":"Infineon BTS5240LAUMA1 dual-channel high-side power switch, 21 mOhm Rds(on), 5.5A per channel, 4.5V-28V load range, -40°C to 150°C junction.","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); Cut Tape (CT)","Features":"-","Interface":"On/Off","Input Type":"Non-Inverting","Output Type":"N-Channel","Switch Type":"General Purpose","Rds On (Typ)":"21mOhm","Mounting Type":"Surface Mount","Package / Case":"12-BSOP (0.295\\\", 7.50mm Width) Exposed Pad","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":"2","Base Product Number":"BTS5240","Output Configuration":"High Side","Ratio - Input:Output":"1:1","Operating Temperature":"-40°C~150°C(TJ)","Current - Output (Max)":"5.5A","Supplier Device Package":"PG-DSO-12-2","Voltage - Supply (Vcc/Vdd)":"Not Required"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/553e5753e00792a95a240852fe945590.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BTS5240LAUMA1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BTS5240LAUMA1 when reusing this data.
