Operating Waveform When Driven by Square Wave
Hall signal
Output waveform
Note: The motor is driven by a square wave if REV = Low, i.e., if the Hall signals at start-up are 5 Hz (fosc = 4 MHz)
To stabilize the bootstrap voltage, the lower outputs (X, Y, and Z) are always turned on at the carrier cycle
even during off time. At that time, the upper outputs (U, V, and W) are assigned dead time and turned off
at the timing when the lower outputs are turned on. (T
When the motor is driven by a square wave, acceleration or deceleration is determined by voltage V
motor accelerates or decelerates according to the On duty of T
