The IRMCK341 is a complete high-performance motor control IC designed for sensorless control of permanent magnet synchronous motors (PMSM) and AC induction motors. It integrates all the necessary functions for motor control, including a microcontroller, gate drivers, and protection features.

Applications:

• Washing Machines
• Refrigerators
• Air Conditioners
• Fans
• Pumps

Features:

• Sensorless Field Oriented Control (FOC)
• Integrated gate drivers for 6 external MOSFETs or IGBTs
• Over-current, over-voltage, and over-temperature protection
• Built-in microcontroller with pre-programmed motor control algorithms
• Serial communication interface (SCI) for parameter setting and monitoring
• DC bus voltage sensing

Benefits:

• Reduced system cost and complexity due to integrated functionality.
• Improved motor efficiency and performance with sensorless FOC.
• Enhanced system reliability with built-in protection features.
• Simplified motor control design with pre-programmed algorithms.
• Flexible parameter adjustment and monitoring through the serial communication interface.

Technical Specifications:

The IRMCK341 operates from a single 15V power supply. It can drive motors up to several kilowatts, depending on the external power stage components. The operating temperature range is -25°C to +85°C. The device is available in a compact QFN package.
