High performance Multi Half-Bridge Motor Driver for Intelligent Motor Control in Stock

When the motor rotor turns to the position where the hall-sensor senses another set of signals, the control unit turns on the next set of power transistors again, so that the circulating motor can continue to turn in the same direction until the control unit decides to stop the motor rotor and turn off the power transistors (or only turn on the lower arm power transistors); If the motor rotor is reversed, the power transistor turns on in reverse order.

When the motor of the brushless motor driver rotates, the control unit must first determine the order of opening (or closing) the power transistors in the converter according to the position of the motor rotor sensed by the hall-sensor, and then according to the stator winding, AH, BH, CH (these are called upper arm power transistors) and AL, BL, CL (these are called lower arm power transistors) in the converter, Make the current flow through the motor coil in order to generate a clockwise (or reverse) rotating magnetic field and interact with the magnet of the rotor, so that the motor can rotate clockwise/counterclockwise.
