The Infineon IRMCK203 is a dedicated controller for commutation and direction management of AC synchronous motors, with a pre-driver output stage designed to drive external IGBT power stages.
The IRMCK203 supports I²C, SPI, RS-232, RS-422, and parallel interfaces, giving the system architect multiple options for host controller communication without external protocol translators.
Infineon has not published a direct replacement or pin-compatible successor for the IRMCK203. Designers needing a similar function should evaluate current-generation motor-control ASICs from Infineon or other vendors, verifying interface, supply, and package compatibility.
