8.3.7.3 Protection for Loss of Power Supply
When loss of supply occurs, the output is shut down regardless of whether the INx pin is high or low. For a resistive or a capacitive load, loss of supply has no risk. But for a charged inductive load, the current is driven from all the I/O pins to maintain the inductance current. To protect the system in this condition, TI recommends the external free-wheeling diode as shown in Figure 33.
