- Infineon introduced a compact automotive motor control system-in-package targeting space-constrained vehicle applications.
- The solution integrates MCU, communication, power stage, and driver circuitry into a single package.
Infineon has introduced the Infineon MOTIX TLE9954QSW40-33 motor control SiP, a fully integrated motor driver designed to address increasing miniaturization demands in modern automotive electronics. The device consolidates multiple control and power elements into a single compact package, enabling space-efficient designs for vehicle subsystems such as thermal management pumps, fans, valves, and seat adjustment mechanisms.
Highly Integrated Motor Control Architecture
The solution combines a motor control microcontroller, power supply, communication interface, and a 3-phase bridge driver within one LIQFN-58-1 package. For the first time in this product family, the architecture also integrates the OptiMOS 7 power stage, reducing external components while simplifying system design.
Compact Package with Thermal Optimization
The package design focuses on efficient heat dissipation from the MOSFETs directly to the printed circuit board, helping engineers manage thermal loads in compact electronic control units and other space-limited automotive environments.
Processing and Safety Capabilities
The device operates on an Arm Cortex-M23 core running up to 40 MHz and includes 72 kB of integrated flash memory alongside 6 kB RAM. It is qualified to AEC-Q100 Grade 0 standards and supports functional safety requirements up to ISO 26262 ASIL B.
Target Automotive Applications
This motor control system-in-package is intended for applications that require compact, integrated control electronics while maintaining automotive reliability and safety. Infineon plans to make the device available to customers beginning in early Q2 2026.
