directly before use.
2. For the constant of capacitor, etc., our value established through examination is given for reference.
Adjust the value according to the motor to be used when considering this IC.
3. If the output is not oscillated with the motor used, a capacitor inserted between output coil ends is not necessary.
4. Pins 5 through 7 (U , V , and W ) are not to be used by a user. These are connected inside IC and should
