Current Discharge Path when ENABLE Input During Operation
In Slow Mode, when all output transistors are forced to switch off, coil energy is discharged in the
following MODES:
Note: Parasitic diodes are located on dotted lines. In normal MIXED DECAY MODE, the current does not flow
to the parasitic diodes.
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
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.
