Command blocking
When a fault state has been cleared, the next turn-on commands are ignored by the ASIC during the
command blocking time to avoid thermal overload of the power MOSFET or IGBT driven by the gate
driver.

Logic level
Bias sink current
Pin capacitance
Pin SO* Status Outputs
Secondary-side faults cause the relevant channel to turn off immediately. Fault states are transmitted to
the primary side via the signal transformer interface (option T) or via an optocoupler (option C), in the
latter case with an additional delay. They are then reported at Pin SOA for channel A and at pin SOB for
channel B.
