switches off in case of open input pin. The zener diode protects the input circuit against ESD pulses.
Figure 4
A high signal at the required external small signal transistor pulls the input pin to ground. A logic supply current I
is flowing and the power DMOS switches on with a dedicated slope, which is optimized in terms of EMC emission.
