A high signal at the input pin causes the power DMOS to switch on with a dedicated
slope, which is optimized in terms of EMC emission.

When switching off inductive loads with high-side switches, the voltage
ground potential, because the inductance intends to continue driving the current.

To prevent destruction of the device, there is a voltage clamp mechanism implemented
that keeps that negative output voltage at a certain level (
