Product details

MCE™ controller for appliance motor drives

The Infineon IRMCK343TY is a motor controller from the MCE™ series, handling commutation and direction management for AC synchronous motors. It integrates a pre-driver configurable as three half-bridge outputs, making it a single-chip solution for sensorless or sensored field-oriented control in appliance-class drives. Communication with a host microcontroller runs over I2C, SPI, or RS-232 — the three interfaces share pins, so the firmware selects one protocol at board level.

Frequently asked questions

Is IRMCK343TY obsolete?

Yes, the IRMCK343TY is listed as Obsolete on the manufacturer's record. There is no direct pin-compatible replacement published under the same MCE™ series.

What are the specifications of IRMCK343TY?

The IRMCK343TY is an MCE™ motor controller for AC synchronous motors. It operates from dual supplies (1.62V–1.98V core, 3V–3.6V I/O), communicates via I2C, SPI, or RS-232, and drives three half-bridge outputs.
