It integrates the gate-driver stage for IGBT power switches, so the BOM keeps the controller and driver in one 64-LQFP package rather than splitting them across separate driver ICs. This means Infineon has flagged it for eventual end-of-life — it is not the part to put into a new BOM, and existing designs should identify a pin-compatible or functionally equivalent successor before the LTB window closes. If the IRMCF143TR itself has failed, the NRND status means you want to source a small buffer of known-good parts for repair stock while they are still available through the independent channel. ## Supply rail and temperature — the hard constraints A replacement must match both the logic supply and the gate-drive architecture. ## 64-LQFP footprint — what it connects to The 64-LQFP (10x10 mm) package is a common motor-control footprint. The 0.5 mm pitch demands a PCB with at least four layers for clean fan-out of the three half-bridge gate-drive signals and the I²C/SPI bus lines.","metaTitle":"IRMCF143TR iMOTION Motor Controller, 3V-3.6V, 64-LQFP, NRND","metaDescription":"Infineon IRMCF143TR iMOTION/MCE motor controller, 3-phase pre-driver, I²C/SPI/RS-232, -40°C to 85°C, 64-LQFP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"iMOTION™, MCE™","Package":"Tape & Reel (TR)","Function":"Controller - Commutation, Direction Management","Interface":"I²C, RS-232, SPI","Technology":"IGBT","Applications":"General Purpose","Mounting Type":"Surface Mount","Package / Case":"64-LQFP","Product Status":"Not For New Designs","Voltage - Load":"-","Step Resolution":"-","lifecycle_stage":"eol_hot","Current - Output":"-","Voltage - Supply":"3V ~ 3.6V","Base Product Number":"IRMCF143","Motor Type - AC, DC":"AC, Servo","Motor Type - Stepper":"-","Output Configuration":"Pre-Driver - Half Bridge (3)","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-LQFP (10x10)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.2866","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IRMCF143TR/alternatives.json"},"ai":{"faq":[{"question":"Is the IRMCF143TR obsolete?","answer":"It is not yet fully discontinued, but Infineon has signaled that it is on the path to end-of-life. New designs should select a replacement; existing production should plan a last-time buy or identify a second source."},{"question":"What is the replacement for the IRMCF143TR?","answer":"The closest functional match would be another iMOTION series controller with the same 3-phase pre-driver output, 3V-3.6V supply, and 64-LQFP package — but pin compatibility must be verified against the target application schematic. Contact us with your BOM for a cross-reference search."},{"question":"What supply voltage does the IRMCF143TR require?","answer":"The pre-driver outputs for the IGBT half-bridge are driven from a separate gate-drive supply, which is generated internally or provided externally depending on the application circuit."},{"question":"What is the difference between IRMCF143 and IRMCF143TR?","answer":"The IRMCF143TR is the Tape & Reel (TR) packaging option of the base IRMCF143 device. The silicon and all functional specifications — supply voltage, interfaces, pre-driver outputs, package, temperature range — are identical. The TR suffix only changes the shipping format from tray or tube to tape-and-reel for automated pick-and-place assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IRMCF143TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IRMCF143TR when reusing this data.
