Power Stages
The power stage has a defined switching behavior. Defined slew rates as well as edge shaping support PWM’ing
of the load while achieving lowest EMC emission at minimum switching losses.

5.4 Switching losses for resistive loads
Switching the device on and off may cause switching losses EON and EOFF. In case of a resistive load, the switching
losses depend on the supply voltage Vbb as well as on the load current IL and the junction temperature Tj. Figure 8
shows this dependencies of the switching losses.
