November 5, 2024 /SemiMedia/ — Infineon Technologies AG is introducing the MOTIX™ TLE9189 gate driver IC, designed for safety-critical applications involving 12 V brushless DC (BLDC) motors. This new three-phase gate driver IC addresses the increasing demand for motor control integrated circuits needed for by-wire solutions. It meets AEC Q100 Grade 0 and ISO 26262 (ASIL D) qualifications, making it particularly well-suited for applications in brake-by-wire and steer-by-wire systems, where traditional mechanical connections are expected to be phased out in the future.

“With the TLE9189 we are introducing the 4th generation automotive 3-phase smart gate driver IC to the market. It offers enhanced functionalities and unique features for intelligent motor control supporting the increasing demand of our customers for by-wire-solutions,” said Andreas Doll, Senior Vice President and General Manager Smart Power from Infineon. “The high reliability of the motor control design enabled by our new device is particularly important for safety-critical by-wire solutions.”

The MOTIX TLE9189 gate driver IC will be available in two different packages, the TQFP-48 (9 x 9 mm²) and the VQFN-48 (7 x 7 mm²). This allows customers to select the appropriate package for their application requirements. The device's supply voltage range is from 4.2 V to 36 V and is optimized for 12 V automotive battery systems. It features a conventional motor control concept consisting of PWM input and integrated current sense amplifiers for accurate current sensing. Compared to other devices, the TLE9189 offers very high flexibility and granularity for gate sequencing. In addition, various monitoring and diagnostic functions are integrated for monitoring of the device, the inverter, the microcontroller and the MCU interfaces. The product also features the unique adaptive MOSFET control function, patented by Infineon, which can help improve EMC performance, achieve target switching time and reduce power losses.

Infineon supports its customers during the design-in process with comprehensive support materials. These include a wide range of technical documentation like application notes. Simulation models, configuration tools and a complex device driver are available on request.
