D340B Design Ideas
I. Driving Multi-Segment Lamps
The D340B may be used to drive two or more EL lamps or EL lamp segments independently. An external switching
circuit can be used to turn each lamp segment on or off. A high signal at the E input for the corresponding EL lamp will
power the segment when the IC is enabled. In this example, Segment 1 is always on when the Durel D340B is enabled.
Otherwise, always make sure that at least one segment is switched on when the driver IC is activated.
II. Enabling the D340B with a High Logic Signal
A low logic signal at the E’ pin will enable the D340B. Adding a transistor and two resistors will allow the D340B to
be enabled with a high voltage signal.
