These pins should not be loaded directly. 2. Capacitors C1 to C5 with a breakdown voltage of 20 V or higher are recommended. And it is recommended to insert the capacitor that is 0.1 µF to 1 µF between VCC and GND. 3. If VCHA is kept low level (in 5 V mode), capacitor C5 is not necessary. 4. The pull-up resistors at driver input are active resistors. |
