Start/stop control pin.
Start with L and stop with H or in the open
condition.
Control circuit power pin.
GND pin (control circuit block).
Pin to set the PWM oscillation frequency.
Connect a capacitor between this pin and GND.
PWM waveform comparator pin.
Normally use with “L” or open. To control the
output duty by applying the voltage to this pin
without using the PWMIN pin, set the PWMIN pin
to “L”.
Pin to set the operation time of motor lock
protection circuit.
Insertion of a capacitor (about 10μF) between
CSD and GND enables setting of the protection
operation time of about 3.5sec.
