Low side gate driver supply
Logic ground
Logic input for high side gate driver outputs (HOP/HON)
Logic input for low side gate driver outputs (LOP/LON)
Dual function (in/out) active low pin. Refer to Figs. 15, 17, and 18. As an output, indicates fault condition.
As an input, shuts down the outputs of the gate driver regardless H
Dual function (in/out) active low pin. Refer to Figs. 15, 17, and 18. As an output, indicates SSD sequence
is occurring. As an input, an active low signal freezes both output status.
Fault clear active high input. Clears latched fault condition (see Fig. 17)
