MCT8329A High Speed Sensorless Trapezoidal Control Three-phase BLDC Gate Driver

The MCT8329A provides a single-chip, code-free sensorless trapezoidal solution for applications requiring high speed operation or very fast startup time for three phase brushless-DC motors. The device provide three half-bridge gate drivers, each capable of driving high-side and low-side N-channel power MOSFETs. The device generates correct gate drive voltag.
