Pin to set the PWM oscillation frequency.
Connect a capacitor between this pin and GND.
Control voltage input pin. For control with this pin, set the
PWMIN pin to the L level.
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 (150kW, 4700pF) in parallel between this pin and
GND.
Start/stop control pin. Start with L and stop with H or in the
open condition
PWM pulse input pin. 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.
