The TLE994x and TLE995x are two new solutions for brushed (BDC) and brushless (BLDC) motor applications that Infineon Technologies is adding to its MOTIX 32-bit motor control SoC (System-on-chip) family.
The new MOTIX SoCs, which range from features like seat adjustment to battery cooling in electric vehicles, are designed for small- to medium-sized automotive motors. These motors are utilized in a growing variety of safety-critical applications and are becoming more and more common in modern, particularly electric ones.
As a result, manufacturers need reliable, small, and reasonably priced solutions that combine several features. The new Motix SoCs combine superior integration with functional safety and cybersecurity-relevant capabilities, drawing on Infineon’s vast experience in motor control.
Based on the scalable TLE99xx architecture, Infineon presents a new generation of the MOTIX MCU family with the TLE994x/5x series. Future product hardware and software efficiencies are made possible by this unified approach, which streamlines design and boosts development productivity.
Infineon also offers a whole development ecosystem, which includes evaluation boards, setup and simulation tools, and specialized software packages, to speed up evaluation and design-in. Faster time-to-market, robust performance, and quick prototyping are further supported by a 150 W water pump reference design and application-optimized FOC motor control software.
By Combining a Gate Driver, Microcontroller, Communication Interface, and Power Supply in a Single Chip, Infineon’s MOTIX 32-bit Motor Control SoCs Offer:Â
- Exceptional functionality with minimal footprint.
- New LIN-based devices feature an Arm Cortex-M23 core running up to 40 MHz, with integrated flash and RAM.
- Field-Oriented Control (FOC) capability ensures efficient and precise motor operation.
- Compared to the established TLE986x/7x family, the TLE994x/5x offers enhanced peripherals, flexible PWM generation via the CCU7, and automatic LIN message handling to reduce CPU load.
- All devices comply with ISO 26262 (ASIL B) for functional safety. Additionally, the integrated Arm® TrustZone technology provides a foundation for improved system security.
Key Applications Include:
The three-phase TLE995x (BLDC) is ideal for pumps and fans in thermal management systems, while the two-phase TLE994x (BDC) targets comfort functions such as electric seats and power windows.
Both devices integrate advanced diagnostic and protection functions that support reliable motor operation.
Availability
The MOTIX SoCs TLE994x/5x devices are in production.
