An optional filter capacitor can be added to each pin in order to filter noise injection, which can alter the status of

the configuration pins. The filter capacitor can be chosen as a trade-off between the filtering capability and the

time required for stabilization at startup.

Propagation delays

The propagation delays between the edges of the digital inputs and the actuation of the gate drivers are

represented in Figure 17, Figure 18, and Figure 19.
