TOC

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”.

CSD

Pin to set the operation time of motor lock

protection circuit.

VCC

Insertion of a capacitor (about 10μF) between

CSD and GND enables setting of the protection

operation time of about 3.5sec.
