Infineon Launches MOTIX™ Motor Control SiP with Integrated MCU

Munich, Germany - Infineon Technologies AG., has introduced the MOTIX™ TLE9954QSW40-33, its first fully integrated motor control System-in-Package (SiP) for automotive applications. The new driver is designed to support extreme miniaturization and intelligent motor control, addressing the growing demand for compact solutions in space-constrained vehicle environments.

Mr. Andreas Doll, Senior Vice President and General Manager Smart Power at Infineon, said “By integrating all essential motor control functions, including power stages, into a single package, our customers can reduce the component count by up to 30 percent compared to discrete designs and can realize 40 percent smaller circuit boards, This allows highly compact designs in applications such as thermal management systems in electric vehicles – including pumps, fans, and valves – as well as comfort functions such as seat adjustment.”

The MOTIX™ TLE9954QSW40-33 is built on a highly integrated architecture that combines a motor control microcontroller, power supply, communication interface, 3-phase bridge driver, and the OptiMOS™ 7 power stage within a single LIQFN-58-1 package. This design improves heat dissipation from MOSFETs to the PCB, enabling high power density while reducing parasitic inductance and enhancing EMC performance, particularly at high switching frequencies. The high level of integration allows PCB designs for automotive comfort systems to be extremely compact—potentially smaller than a postage stamp. The solution also includes a 150 W water pump reference design, capable of delivering higher power under optimized thermal conditions.

The device features an Arm® Cortex®-M23 core running at up to 40 MHz, with 72 kB flash memory and 6 kB RAM. It supports field-oriented control (FOC) for efficient and precise motor operation, while the CCU7 timer unit enables flexible PWM generation and automatic LIN message processing to reduce CPU workload. Integrated Arm® TrustZone® technology provides hardware-based isolation for safety- and security-critical functions. With AEC-Q100 Grade 0 qualification and support for ISO 26262 up to ASIL B, the device meets stringent automotive reliability and safety standards. In addition, the MOTIX MCU (SiP) is supported by a comprehensive ecosystem including hardware kits, reference designs, specialized software packages, development tools, and optimized FOC motor control software to enhance design flexibility and accelerate time to market.
