Figure 9 and 11 show the STEVAL-IFP010V3 temperature map with all channels

permanently switched ON, 48

Ω loads, 24 V supply voltage and ambient temperature of

25 °C.

The IC temperature increase is only about a few degrees.

Figure 10 and 12 show a similar

map when the IC is cycling at 1 Hz, 50% duty cycle, 48

Ω, 1.2 H loads, 24 V supply voltage

and ambient temperature of 25 °C.

In particular

Figure 11 and 12 show a 3D thermal modelization of the device.
