2 Introduction

The MCT8316A provides three half-H-bridge integrated MOSFET drivers with sensorless trapezoidal control to drive a three-phase brushless DC (BLDC) motor at 12-V/24-V DC rails or battery powered applications. The device integrates three current-sense amplifiers (CSA) with integrated current sense for sensing the three phase currents of BLDC motors to achieve optimum trapezoidal control. Simplified schematic of MCT8316A is shown in Figure 2-1.

Figure 2-1 Simplified Schematic of MCT8316A.

This tuning guide provides the steps to tune a 3-phase BLDC motor using the MCT8316A. The tuning process is classified into two sections: Essential controls and Basic controls. This process is also detailed in the Guided tuning section in the GUI.

  • Essential controls: Tuning steps to successfully spin the motor in closed loop

  • Basic controls: Tuning steps to conform to use-case and explore features in the device
