It combines commutation logic, direction management, and a three-phase half-bridge pre-driver output stage in a single 48-LQFP package. ## Half-bridge pre-driver – external power stage required The three half-bridge pre-driver outputs (rated as Power MOSFET technology) drive an external inverter stage — the IRMCF171TY does not integrate the power switches. The designer selects external MOSFETs or IGBTs matched to the motor voltage and current. The gate drive strength and dead-time are managed internally by the MCE, so the BOM adds six power devices plus bootstrap diodes. ## Industrial temp grade and appliance-class deployment ## NRND – last-time-buy planning recommended Existing production runs should secure last-time-buy quantities or qualify a drop-in replacement. For new designs, Infineon recommends evaluating the current iMOTION IMM series or a comparable MCE-based controller. ## Sourcing posture Buyers with an active BOM line should request a quote promptly to lock allocation before the last-time-buy window closes.","metaTitle":"IRMCF171TY motor controller, iMOTION, NRND, 48-LQFP","metaDescription":"Infineon IRMCF171TY iMOTION MCE controller for AC induction/synchronous motors. 3V-3.6V supply, I²C/SPI/RS-232, half-bridge pre-driver.","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":"Tray","Function":"Controller - Commutation, Direction Management","Interface":"I²C, RS-232, SPI","Technology":"Power MOSFET","Applications":"Appliance","Mounting Type":"Surface Mount","Package / Case":"48-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":"IRMCF171","Motor Type - AC, DC":"AC, Induction, Synchronous","Motor Type - Stepper":"-","Output Configuration":"Pre-Driver - Half Bridge (3)","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.3479","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IRMCF171TY/alternatives.json"},"ai":{"faq":[{"question":"Is IRMCF171TY obsolete?","answer":"It is not yet fully discontinued, but Infineon advises against using it in new designs.
