I. Driving Multiple EL Lamps
The D371 may be used to drive multiple EL lamp segments. An external transistor switching circuit is used to turn each lamp
segment on or off independently or simultaneously. A high signal at the corresponding E input will enable the corresponding
lamp segment. In this configuration, EL Lamp 1 is always turned on when the IC is enabled. Otherwise, always make sure
that at least one lamp segment is selected to be on when the D371 is enabled.

II. Two Level Dimming
Two level dimming may be achieved with the circuit below. When DIM is low, the external PNP transistor (2N3906 or
equivalent) is saturated and the EL lamp runs at full brightness. When DIM is high, the external PNP turns off and the
Rswitch resistor reduces the voltage at (V+) and dims the EL lamp.
