A new generation of motor-control system-on-chips is setting fresh benchmarks in automotive design — merging power, safety, and cybersecurity in compact, cost-efficient devices that drive everything from cooling systems to comfort features in modern vehicles.
Infineon Technologies has expanded its MOTIX 32-bit motor control system-on-chip (SoC) lineup with the new TLE994x and TLE995x series, designed to power the growing ecosystem of small to medium automotive motors. These new SoCs target both brushed (BDC) and brushless (BLDC) applications, offering automakers a compact, cost-effective way to deliver reliable performance across safety-critical and comfort systems.
The key features are:
- Powered by Arm Cortex-M23 core running up to 40 MHz
- Integrated flash and RAM for efficient processing
- Combines gate driver, MCU, LIN interface, and power supply in one chip
- Compact design reduces footprint and simplifies system integration
- Three-phase version supports BLDC motors for pumps and fans
- Two-phase version targets BDC motors for comfort functions like seats and windows
The new family members are optimized for key functions in modern vehicles — from thermal management systems like battery cooling pumps and fans to convenience features such as electric seat adjustments and power windows. As electric vehicles incorporate more electronically controlled components, the latest SoCs respond to the need for tighter integration, functional safety, and cybersecurity readiness.
The devices feature Field-Oriented Control (FOC) for efficient and precise motor operation, as well as advanced diagnostics and protection mechanisms for dependable performance. Compared to the earlier TLE986x/7x generation, the new series offers enhanced peripherals, flexible PWM generation using the CCU7 module, and automatic LIN message handling to reduce CPU load.
To support rapid evaluation and faster time-to-market, Infineon backs the launch with a complete development ecosystem — including evaluation boards, motor control software, simulation tools, and a 150 W water pump reference design for real-world testing.
