Connection of two EVALSTGAP1S boards

18

If the STGAP1S devices are used in single input configuration both IN-/DIAG2 lines are

shall therefore be connected) it is possible to achieve cross conduction prevention by

driving both drivers with only two µC lines as shown in Figure 5.

Figure 5. Half bridge configuration with hardware shoot-through protection

In order to use this configuration the STGAP1S shall be used as 2-input device and the JP1

and JP2 jumpers shall be properly set (see Table 9).
