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.

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.

The capacitor C5 does not have to be connected when the IC is used in 5 V mode (VCHA = L).
