Function
LB11820M
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.
