21

PWM Pin to set the PWM oscillation frequency.

Connect a capacitor between this pin and GND.

Equivalent circuit

22

VCTL Control voltage input pin. For control with this pin,

set the PWMIN pin to the L level.

23

CSD Pin to set the operation time of motor lock protection

circuit and to set the initial reset pulse.

Connect a capacitor between this pin and GND.

When the protection circuit is not to be used,

connect a capacitor and resistor (150 kΩ, 4700 pF)

in parallel between this pin and GND.

24

S / S Start/stop control pin.

Start with L and stop with H or in the open condition.

25

PWM PWM pulse input pin.

IN

Output drive with L and output OFF with H or in the

open condition. For control with this pin, apply the

voltage of VCTL2 voltage or more to the VCTL pin.
