IRMCK172MTR

Overview

The IRMCK172MTR is a motor controller and driver IC from Infineon Technologies, designed for brushless DC (BLDC) motor applications. It integrates control logic with gate drive capabilities to manage motor phases efficiently. The device operates within a supply voltage range of 3V to 3.6V and supports communication via I2C or SPI interfaces. It is housed in a 48-QFN package measuring 7x7 mm with an exposed pad for thermal management. The component is rated for an operating temperature range of -40°C to 85°C (TA). This integrated solution simplifies the design of compact motor control systems by combining necessary power and control functions into a single chip.

Feature Summary

• Integrates motor control logic with gate drive functionality for BLDC motors
• Supports digital communication through I2C and SPI interfaces
• Designed for surface mount assembly in compact form factors

Applications

• Appliance motor control systems
• Compact BLDC motor drives
• Embedded motion control solutions

Procurement Notes

Verify the exact suffix and revision level against the manufacturer's current datasheet to ensure compatibility with your specific design requirements. Confirm that the 48-QFN package dimensions match your PCB footprint exactly. Check for any updated lifecycle status or alternative recommendations from Infineon, as availability may vary. Ensure that the 3V-3.6V supply voltage range aligns with your system's power architecture before finalizing procurement.

Selection Notes

Select this component when a highly integrated solution for BLDC motor control is required to minimize board space and component count. It is suitable for applications where digital control via I2C or SPI is preferred over analog inputs. Consider the 3V-3.6V supply constraint and ensure your system can provide stable power within this range. The 48-QFN package requires appropriate thermal design considerations due to the exposed pad, which must be soldered to the PCB for effective heat dissipation during operation.

Part Context

The IRMCK172MTR belongs to Infineon's family of motor driver and controller integrated circuits. These components are engineered to simplify the implementation of brushless DC motor drives in consumer and industrial appliances. By integrating control algorithms and power stages, they reduce the complexity of motor control designs compared to discrete solutions. This specific model focuses on low-voltage applications, offering a compact footprint suitable for space-constrained devices requiring efficient and reliable motor management.

Replacement Considerations

Consult Infineon's official cross-reference tools for verified substitute part numbers. Do not assume functional equivalence with other models in the IRMCK series without verifying pinout, voltage ranges, and interface compatibility. Always refer to the latest datasheets for potential revisions or end-of-life notices.
