Infineon – iMOTION™ IMC300 series – PMSM/BLDC motor controller with additional 32-bit microcontroller

Infineon – iMOTION™ IMC300 series – PMSM/BLDC motor controller with additional 32-bit microcontroller

The iMOTION™ IMC300 series is a family of motor control ICs with an additional user programmable microcontroller. It is suitable for variable speed motor control systems in Major and Small Home Appliances, and in motor drives requiring high application flexibility. The IMC300 series combines the iMOTION™ Motion Control Engine (MCE 2.0) with an additional microcontroller based on the Arm® Cortex®-M0 core. The MCE provides ready-to-use motor and optional PFC control and integrates all required components for a minimal BOM. It integrates multiple protection features, can be configured for almost any motor and achieves highest energy efficiency.The additional microcontroller (MCU) provides a flexible peripheral set and multiple communication interfaces. It runs fully independent from the MCE and can be used for configuration, command and control via an internal high speed interface. IMC300 devices can be used in applications requiring functional safety acc. to UL/IEC 60730 (‘Class B’).
