Functional Description
2.3.2 Low Side Filament Detection during Run Mode
In case of an open low side filament during Run mode, the current out of the RES pin I
= - 21.3 µA
RES3
charges up the capacitor C19 in Figure 3. If the voltage at the RES pin exceeds the V
= 3.2V
RES3
threshold, the controller detects an open low side filament and stops the gate drives after a delay of t =
620µs of an internal timer.
Figure 10: Open Low Side Filament Run Mode
Figure 11: Restart from open LS Filament
A restart is initiated when a filament is detected e.g. in case of a lamp removal. In case of a filament is
present (Figure 11 section 2), the voltage drops below 1.3V and the value of the source current out of
the RES pin is set from I
= - 17.7 µA up to I
= - 21.3 µA. The controller powers up the system
RES4
RES3
including Soft Start and Preheating into the Run mode (Figure 11 section 3).
