The TLE9189QVW from Infineon Technologies is an Automotive-Qualified Three-Phase Gate Driver IC that has been designed to control 6 external N-channel power MOSFETs for high-current 3-phase motor drive applications. It requires an input voltage of 4.2 - 36 V. This gate driver has current source-controlled output stages with adaptive MOSFET gate control for dynamic switching characteristics optimization. It integrates 3 current sense amplifiers and has an adjustable duty cycle for accurate current measurement while reducing signal noise in sensitive environments. This AEC-Q100 Grade 0-qualified gate driver complies with ISO 26262 ASIL-D standards and includes built-in self-test functions with low FIT rates for improved reliability. It also enables communication with a serial peripheral interface (SPI) to offer extended monitoring and diagnostic functions through fault monitoring and reporting.
This gate driver has an exposed pad for optimized thermal performance and provides special leads allowing an automated optical inspection. It operates in a low quiescent current mode for improving energy efficiency and extending battery life. This RoHS-compliant gate driver is available in a surface-mount package that measures 7 x 7 mm and is ideal for electric power steering (EPS), electric brake booster (EBB), functional safety-related BLDC, or PMSM motor drive applications.
