Boost charge and discharge circuits
In order to keep the output response time constant during mode transfer from the standby state to forward (reverse)
rotation, this IC incorporates boost charge and discharge circuits for external capacitor connected to the FC pin.
The external capacitor connected to the FC pin is for output phase compensation (to suppress oscillation), for which
0.01 to 0.1μF is recommended. Note that increase in the capacitor value results in increase in the time necessary for
the constant current control to rise.
