The controller is designed to drive external Power MOSFETs or IGBTs, so the pre-driver outputs feed the gate drive stage, not the motor windings directly. This keeps the high-current switching outside the controller package. No official replacement or successor part is recorded in the available documentation.","metaTitle":"IRMCF311TR MCE™ Motor Controller, Obsolete – Sourcing Info","metaDescription":"IRMCF311TR MCE™ motor controller from Infineon.
