IRMCK143TR

Overview

The IRMCK143TR is a mixed-mode digital signal controller from Infineon Technologies, designed for sensorless motor control applications. It integrates an IGBT driver with a high-performance DSP core. The device operates on a supply voltage range of 3V to 3.6V and is housed in a 64-LQFP (12x12 mm) surface-mount package. It supports I2C, RS-232, and SPI interfaces for communication. The component is rated for an operating temperature range of -40°C to 85°C and features three half-bridge pre-drivers.

Feature Summary

• Integrates a mixed-mode DSP core with IGBT technology for sensorless motor control
• Includes three half-bridge pre-drivers for motor phase management
• Supports multiple communication protocols including I2C, RS-232, and SPI

Applications

• Sensorless AC and DC motor control systems
• Servo motor drive applications
• General purpose motor driver implementations

Procurement Notes

Verify the specific suffix and package dimensions carefully, as distributor listings may confuse this model with similar variants like the IRMCF143TR which uses a different footprint. Confirm end-of-life status with the manufacturer before finalizing designs, as availability may be restricted. Ensure the selected variant matches the required interface and thermal specifications for the target application environment.

Selection Notes

Select this component when a combined DSP and power driver solution is required for sensorless applications. Compare against the IRMCF143TR if a standard LQFP package is preferred over the larger 12x12mm form factor. Evaluate the mixed-mode architecture benefits for reducing external component count in AC, DC, and servo motor drives requiring integrated commutation logic.

Part Context

This part belongs to Infineon's iMOTION and MCE series of microcontrollers. It represents a specialized class of mixed-signal controllers that combine digital processing capabilities directly with power stage drivers. This integration simplifies the design of compact motor control systems by reducing the need for separate microcontroller and gate driver components.
