It integrates an IGBT pre-driver in a half-bridge (3) output configuration, meaning it handles the gate drive signals for a three-phase inverter stage directly. Communication with a host microcontroller or DSP goes through I²C, SPI, or RS-232 interfaces — the three serial buses cover most embedded control architectures, from sensorless FOC to trapezoidal commutation schemes. The dual-voltage architecture is typical for mixed-signal motor controllers that keep the logic core at a lower voltage while the I/O interfaces with 3.3 V peripherals. ## Package — 48-LQFP, 7x7 mm body Housed in a 48-lead LQFP (7x7 mm body).","metaTitle":"IRMCK371TR MCE motor controller, obsolete, 48-LQFP","metaDescription":"IRMCK371TR by Infineon is an obsolete MCE motor controller for AC synchronous motors with IGBT pre-driver.
