Current Discharge Path when Current Data
=
0000 are Input during Operation
In Slow Decay 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. However, when signal 0000 is input during operation, the current flows to them.
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.
