VREG Connect a capacitor (about 0.1 µF) between this pin and GND for
stabilization
Pin to set the PWM oscillation frequency.
7
PWM Connect a capacitor between this pin and GND.
This can be set to about 18 kHz with C =3900 pF.
VREG
VREG
Pin to set the operation time of motor lock protection circuit.

CSD
Connection of a capacitor (about 10 µF) between CSD and GND
can set the protection operation time of about 3.3seconds.
