LV8732V
Charge Pump Circuit
When the ST pin is set High, the charge pump circuit operates and the VG pin voltage is boosted from the VM voltage
to the VM + VREG5 voltage. If the VG pin voltage is not boosted sufficiently, the output cannot be controlled, so be
sure to provide a wait time of tONG or more after setting the ST pin High before starting to drive the motor.
