Overview
The IRMCK371TR is a sensorless motor controller and driver IC from Infineon Technologies, part of the MCE series. It integrates an ARM7 core for control logic with three half-bridge pre-drivers for IGBT or MOSFET switching. The device supports AC, DC, and synchronous motors using field-oriented control algorithms. It operates within a supply voltage range of 1.62V to 1.98V and 3V to 3.6V. The component is housed in a 48-QFP (7x7) package and functions between -40°C and +85°C.
Feature Summary
- Integrates ARM7 processor core with embedded FOC algorithms for sensorless motor control
- Includes three half-bridge pre-drivers compatible with IGBT and MOSFET power stages
- Supports multiple communication interfaces including I2C, RS-232, and SPI
Applications
- Home appliance motor control systems
- Industrial motion control applications
- Automotive ignition and motor drive circuits
Procurement Notes
This component is officially obsolete and no longer manufactured by Infineon Technologies. Procurement should focus on verified parametric equivalents such as the IRMCK371TY. Verify datasheet revisions and substitute part compatibility before integration into new designs.
Selection Notes
Select this part only for legacy system maintenance or repair where original specifications are mandatory. For new designs, evaluate current alternatives like the IRMCK371TY which offers similar functionality. Ensure interface requirements match I2C, RS-232, or SPI capabilities.
Part Context
The IRMCK371TR belongs to Infineon's MCE (Motor Control Engine) family, designed for high-performance brushless DC and synchronous motor applications. It combines digital control processing with analog power driver stages in a single integrated circuit solution.
Replacement Considerations
The IRMCK371TY is a confirmed parametric equivalent substitute. Both parts share identical electrical characteristics and pinouts. Verify package compatibility and firmware compatibility when transitioning from the obsolete TR suffix variant.
