9.1.18 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 ).
