It integrates a pre-driver configured as three half-bridge outputs — the standard topology for a three-phase inverter driving a permanent-magnet synchronous motor (PMSM) or brushless DC (BLDC) motor in appliance-class applications. Communication with a host microcontroller runs over I²C, RS-232, or SPI — the RS-232 port is unusual for a motor controller and suggests a legacy calibration or debug interface on the production line. ## Dual supply rails — plan the BOM The 64-LQFP package (10×10 mm body, 0.50 mm pitch) is a standard footprint for a controller of this complexity. It is not qualified for under-hood automotive (125°C ambient) or extended industrial (105°C). For a production BOM line, this part is a single-source risk. If the design is still in development, a pin-compatible or functionally equivalent alternative should be qualified before the current stock channel dries up.","metaTitle":"IRMCK343TR MCE™ motor controller, obsolete","metaDescription":"IRMCK343TR MCE™ controller for AC synchronous motors, 64-LQFP, -40°C to 85°C, I²C/RS-232/SPI.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"MCE™","Package":"Tape & Reel (TR)","Function":"Controller - Commutation, Direction Management","Interface":"I²C, RS-232, SPI","Technology":"IGBT","Applications":"Appliance","Mounting Type":"Surface Mount","Package / Case":"64-LQFP","Product Status":"Obsolete","Voltage - Load":"-","Step Resolution":"-","lifecycle_stage":"eol_hot","Current - Output":"-","Voltage - Supply":"1.62V ~ 1.98V, 3V ~ 3.6V","Base Product Number":"IRMCK343","Motor Type - AC, DC":"AC, Synchronous","Motor Type - Stepper":"-","Output Configuration":"Pre-Driver - Half Bridge (3)","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"64-MQFP (10x10)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.0500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3f7e758c0c0c42d6a5b0cc6deee821e2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IRMCK343TR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for IRMCK343TR?","answer":"No official replacement or successor order code is listed by Infineon.
