The IC comparators are then set to a threshold of V
the voltage at the RES pin drops below V
When a filament is present
out of the RES pin is set from I
including soft start and preheating, into the run mode.
2.3.2
In the case of an open low side filament during run mode, the current flowing out of the RES pin I
charges up the capacitor C19 in
controller detects an open low side filament and stops the gate drives after a delay of t = 620 µs of an internal timer.
