Evaluation board

MCT8316AEVM — MCT8316A evaluation module for three-phase sensorless trapezoidal BLDC motor driver

The MCT8316A is three half-H-bridge integrated MOSFET drivers for sensorless trapezoidal control of a three-phase brushless DC (BLDC) motor for 4.5-V to 35-V,  8-A peak current drive. The MCT8316A integrates a buck regulator that can support 200-mA with programmable regulated supply. EVM (...)
