Smart High-Side Switch BSP742R
Protection: Loss of Ground detection

The BSP742R is high side power switch with integrated vertical power
FET, providing embedded protection and diagnostic functions.

This circuit demonstrates the loss of Ground protection features of the
BSP742R. Many other switches provide similar protection features.
