GATECFG1

The GATECFG1 register has the following structure:

The IGATE parameter selects the sink/source current used by gate driving circuitry to

charge/discharge the respective gate during commutations. Seven possible values ranging

from 4 mA to 96 mA are available, as shown in Table 28.

The TCC parameter defines the duration of constant current phase during gate turn-on and

turn-off sequences (Section 6.15).
