Overview
The IRMCK203 is a dedicated motor control integrated circuit manufactured by Infineon Technologies, designed for sensorless drive applications. It operates as a complete design platform within the iMOTION development system, supporting 60 kHz switching frequencies. The device accepts an input voltage of 115 VAC and provides a regulated output voltage of 5 V with an output current capability of 4 mA. It features multiple interface options including I2C, parallel port, SPI, RS-232, and RS-422. Packaged in an 80-QFP (12x12) format, it supports AC and synchronous motors using IGBT technology.
Feature Summary
- Supports sensorless drive design platforms for motor control applications
- Integrates multiple communication interfaces including I2C, SPI, and parallel ports
- Provides pre-driver output configuration for gate control
- Includes direction management and commutation control functions
Applications
- Sensorless motor drive evaluation
- iMOTION development system integration
- General purpose motor control prototyping
Procurement Notes
Verify component status carefully as the IRMCK203 is listed as obsolete or discontinued in major distributor databases. Confirm availability through authorized channels or secondary markets if sourcing is required. Ensure that any replacement strategy accounts for the end-of-life status to prevent supply chain disruptions for existing designs.
Selection Notes
Select this component only for legacy systems or specific evaluation purposes where the iMOTION ecosystem compatibility is critical. Due to its discontinued status, new designs should consider modern alternatives from the manufacturer's current portfolio. Evaluate interface requirements against the available I2C, SPI, and parallel options to ensure system compatibility.
Part Context
The IRMCK203 belongs to the iMOTION family of motion controllers and drivers developed by International Rectifier, now part of Infineon Technologies. It serves as a specialized IC for evaluating sensorless motor control algorithms without requiring physical position sensors. The device is often paired with the IRMCS2031 development kit for comprehensive testing.
Replacement Considerations
Public confirmed substitute part numbers are not available due to the component's discontinued status. Designers must evaluate newer motor control ICs from the manufacturer's current lineup that offer similar interface capabilities and support for sensorless operation.
