PRODUCTION DATA
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 thermal pad (Tab), IC_GND, and current limit ground are one trace connected to the system ground, as shown in Figure 8-17.
Case 2 (loss of module GND): when the whole ECU module GND is lost, protections are also active. At this condition, the load GND remains connected.
