Infineon MOTIX™ TLE9189QVW and TLE9189QUW
Gate driver ICs for BLDC motors
MOTIX™ TLE9189 is a 3-phase gate driver IC designed for 12 V batteries. The device is qualified according to AEC Q100 Grade 0 and ISO 26262 (ASIL D). This makes the device particularly suitable for by-wire systems of the future. The MOTIX™ TLE9189 gate driver IC for BLDC motors will be available in two different packages, the TQFP-48 (9x9 mm²) and the VQFN-48 (7x7 mm²). Comprehensive support materials are available and include technical documentation, simulation models, configuration tools and software (complex device driver).
