Note The pull-up resistors of the driver inputs are active resistors.
Remark 1. VDD and VSS are pins that output the voltage boosted internally. Don't connect these pins to the
load.
2. Capacitors with a breakdown voltage of 20 V or higher are recommended for C1 to C5. And it is
recommended to insert the capacitor that is 0.1 µF to 1 µF between VCC and GND.
3. The capacitor C5 does not have to be connected when the IC is used in 5 V mode (VCHA = L).
