Current Discharge Path when ENABLE is Set as Low During Operation
following modes:
the reverse direction to that in normal operation; as a result, the parasitic diodes are not used. However, when all
the output transistors are forced off, the coil energy is discharged via the parasitic diodes.
OFF
ON
When all the output transistors are forced off during Slow Decay mode, the coil energy is discharged in the
As shown in the figure above, output transistors have parasitic diodes.
Normally, when the energy of the coil is discharged, each transistor is turned on allowing the current to flow in
