When VOUT is shorted to ground, the module power supply (VBB) can have a transient decrease. This is caused by the sudden increase in current flowing through the wiring harness cables. To achieve ideal system behavior, it is recommended that the module maintain VBB > 3 V during VOUT short-to-ground. This is typically accomplished by placing bulk capacitance on the power supply node.
