PWM control function
Applying a PWM signal of 0/5 V to the PWM pin allows motor speed control.
The IC enters CW (CCW) mode and short brake mode alternately in PWM current control.
To prevent shoot-through current caused by simultaneous conduction of upper and lower transistors in
the output stage, a dead time is internally generated for 500 ns (target spec) when switching the upper
and lower transistors.
Therefore, synchronous rectification for high efficiency in PWM current control can be achieved without
an off-time that is generated via an external input.
Even when toggling between CW and CCW modes, and CW (CCW) and short brake modes, the off-time
is not required due to the internally generated dead time.
