Figure 18
The case when the device switches on into an existing short circuit - Short circuit type 1- is shown in
The test setup for short circuit characterization is shown in
Therefore it can be assumed that the micro controller and device GND connection have a low impedance. All
impedance in the short circuit path is merged in the short circuit resistance R
