Product details

MCE motor controller for AC synchronous drives

The Infineon IRMCK371TY is a dedicated commutation and direction management controller from the MCE series, designed to drive AC synchronous motors through an external IGBT power stage. It integrates a pre-driver half-bridge output stage for three-phase inverter control and communicates over I²C, SPI, or RS-232 for parameter setup and monitoring. Typical deployment is in appliance motor drives where a single-chip control solution with a serial interface reduces BOM complexity.

Supply rails and interface options

The I²C, SPI, and RS-232 serial interfaces give the designer flexibility in how the motor parameters and commutation profile are programmed — either from an external host MCU over a two-wire bus or through a dedicated setup tool over RS-232.

Frequently asked questions

What is the replacement for IRMCK371TY?

No official replacement or pin-compatible successor is recorded in the available lifecycle data for the IRMCK371TY. Engineers needing a functional replacement should evaluate current-production motor controllers from the same MCE family or from competing suppliers, paying close attention to the pre-driver half-bridge output configuration, dual supply voltage requirements, and serial interface compatibility.

Where can I buy IRMCK371TY?

As an obsolete part, the IRMCK371TY is not available through franchised distribution. It is sourced through independent semiconductor distributors who carry surplus and allocated inventory.
