11. Forward/Reverse Rotation Circuit
12. Start Circuit
13. Brake
The circuit accepts a TTL input and incorporates a pull-up resistor.
Note that abrupt switching between forward and reverse rotation may result in an output FET being
damaged due to reverse torque.
The circuit accepts a TTL input and incorporates a pull-up resistor.
The START input should be asserted High after V
input after the system clock, fx1, has stabilized. Keep in mind that the motor will not start if CLK, START
