The power stages are built to be used in high side configuration
Figure 7
The power DMOS switches with a dedicated slope, which is optimized in terms of EMC emission.
Figure 8
When switching off inductive loads with high-side switches, the voltage
because the inductance intends to continue driving the current. To prevent destruction of the device, there is a
voltage clamp mechanism implemented that limits that negative output voltage to a certain level (
