General Description

The Supertex HV861DB1 demoboard contains all the

necessary circuitry to demonstrate the features of the HV861

dual EL Lamp driver.

Simply connect it to a power supply and a lamp as shown in

Figure 1.

A 2.2µF capacitor is connected between V

allows the lamp to slowly (in about 400ms) brighten up/dim

down during power up/power down. The dimming feature is

common to both lamps.

Board Layout

Connections:

EN1 and EN2: Lamp Selection

CMOS logic inputs which enable/disable the lamp drivers.

When EN1 is connected to V

ON/OFF. When EN2 is connected to V

will be ON/OFF.

Supplies the HV861 EL driver IC. The supplied circuit is op-

timized for 3.0V operation.

Supplies the high voltage power converter. The demoboard

is optimized for 3.2V to 4.2V operation

Note: All of the above connections must be made before powering up the supply voltages.
