This feature gives the customer the flexibility to align the pre heating frequency to the filament power
in the pre heating phase. Figure 32 shows a standard start up with the set preheating time of e.g.
820ms with an 8.2 kΩ resistor at the RTPH pin 11. To force the IC remains in pre heating, the voltage
level at the RTPH pin 11 has to set to 5.0 V. The duration of this 5.0 V signal defines the time of the
pre heating see I
