Connection of two EVALSTGAP1AS boards

Lines SD and DIAG1 of both STGAP1AS drivers are shared, whereas it is possible to

independently control IN+ and IN-/DIAG2 pins of each driver through appropriate lines of the

If the STGAP1AS 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.

In order to use this configuration the STGAP1AS shall be used as 2-input device and the

JP1 and JP2 jumpers shall be properly set (see Table 9).
