Smart High-Side Switch BSP742R
Protection Features: Loss of Vbb detection

Thermal model description:
THERMALMODEL = 1: 1S0P PCB 600mm2
THERMALMODEL = 2: 2S2P no vias
THERMALMODEL = 3: 2S2P vias

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

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