Infineon presents new ASIL-D-compliant 3-phase gate driver IC
Infineon is launching the new MOTIX TLE9189 gate driver IC for safety-critical applications for 12 V brushless DC (BLDC) motors. With this new three-phase gate driver IC, Infineon is responding to the growing demand for motor control ICs required for by-wire solutions. The driver IC is qualified according to AEC Q100 Grade 0 and ISO 26262 (ASIL D). This makes the device particularly suitable for brake-by-wire and steer-by-wire systems, where conventional mechanical connections will be eliminated in the future.
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 optimised 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.
MOTIX TLE9189 gate driver IC in VQFN and TQFP samples are available now. Further information is available at https://www.infineon.com. A demo of the new gate driver IC will be showcased at electronica 2024 in Munich from November 12 to 15 (hall C3, booth 502).
