It integrates a pre-driver stage with six half-bridge outputs — the standard topology for a three-phase inverter driving a power stage built from IGBTs or power MOSFETs. The part is officially obsolete per the manufacturer's lifecycle status. That means no further production runs — any stock in the channel is the last available material. ## Supply rails and interface — what the BOM needs to deliver Communication with a host MCU or system controller goes over I²C, SPI, or RS-232. The RS-232 interface is less common on modern motor drives — if the design uses it, the line driver/receiver is an extra BOM line.","metaTitle":"IRMCF312TR motor controller, MCE series, obsolete","metaDescription":"IRMCF312TR is an obsolete appliance motor controller from the MCE series.
