FIGURE 7. This four phase half wave motor controller uses the same Brake circuit as in Figure 4 and switches
the Top Driver Select from a high to a low as in Figure 6.
FIGURE 8.
Using an analog switch (such as the CD4066) PWM Braking can be employed when the brake is applied.
At that time, the error amplifier is configured as a voltage follower and its input is switched from the
speed adjustment control to the PWM rate control. By adjusting the PWM rate control, the average motor
current during braking can be controlled.
