7.3.4.7 Loss of GND Protection
When loss of GND occurs, output is turned off regardless of whether the input signal is high or low.
Case 1 (loss of device GND): Loss of GND protection is active when the Tab, IC_GND, and current limit GND are
one trace connected to the board GND, as shown in Figure 38. Tab floating is also a choice.
