Overview
The IRMCF312TR is a discontinued microcontroller-based motor driver from Infineon Technologies, part of the MCE series. It integrates a processor core with power drivers for AC, DC, and synchronous motors using Power MOSFET or IGBT technology. The device supports I2C, RS-232, and SPI interfaces and operates within supply voltage ranges of 1.62V to 1.98V and 3V to 3.6V. It features six half-bridge pre-drivers for commutation and direction management. Packaged in a 100-QFP (14x14) surface-mount format, it functions across an industrial temperature range of -40°C to 85°C.
Feature Summary
- Integrates microcontroller processing with integrated power stage pre-drivers for simplified motor control designs.
- Supports multiple communication protocols including I2C, RS-232, and SPI for system integration.
- Provides dedicated hardware functionality for automatic commutation and direction management.
Applications
- Home appliance motor control systems
- AC and DC brushless motor drives
- Synchronous motor applications
Procurement Notes
This component is officially listed as discontinued by the manufacturer. Availability is limited to existing stock; no new production runs are scheduled. Verify end-of-life status and obsolescence notices directly with authorized distributors before finalizing design-in decisions. Sourcing may require checking secondary market channels or approved substitute components.
Selection Notes
Select this component only if legacy support for the MCE architecture is required. Ensure the application utilizes AC, DC, or synchronous motor types compatible with the integrated half-bridge outputs. Confirm that the 100-QFP package dimensions fit the PCB layout constraints. Verify interface compatibility with host controllers supporting I2C, RS-232, or SPI protocols.
Part Context
The IRMCF312 belongs to Infineon's MCE (Motor Control Engine) family, designed to reduce development complexity for motor applications. It combines digital control logic with analog power driver stages. The TR suffix indicates tape-and-reel packaging for automated assembly processes. This specific variant targets cost-sensitive consumer electronics requiring reliable motor management.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation due to the discontinued status. Consult official Infineon replacement guides or contact technical support for current generation equivalents.
