Notes 1. Be sure to connect the VC pin to VCC 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 (UIN, VIN, and WIN) are not to be used by a user. These are connected inside IC and should always be kept independent and open. 5. NC pins (14 and 18) are not connected inside IC and can be used as relay pins.
