Uses a two-way half-bridge drive circuit + low-pass internal resistance 55V110A NMOS, the motor can run forward and backward. Two-way PWM input, duty cycle can be adjusted within 0-99%, with braking capability. Working voltage is 5V-30V and the power is under 170W. The control is extremely simple and convenient, only 3 input lines are needed to control the motor. The chip has built-in dead zone hardware control, which can better adapt to frequent commutation and reduce the loss of the tube itself. Supports 5V, 3.3V logic input, suitable for direct control of IO ports of various types of microcontrollers. The back of the module is tinned and the wiring can conduct more current.
