following MODES:
direction to that in normal operation. As a result, the parasitic diodes are not used. If all the output
transistors are forced to switch off, the energy of the coil is discharged via the parasitic diodes.
In Slow Mode, when all output transistors are forced to switch off, coil energy is discharged in the
As shown in the figure at right, an output transistor has parasitic diodes.
To discharge energy from the coil, each transistor is switched on allowing current to flow in the reverse
