FIGURE 4-2:

180 Hz Output Waveform.

In general, as the EL lamp frequency increases, the

amount of current drawn from the battery will increase.

The color of the EL lamp and the intensity are

dependent upon its frequency.

Enable Function

The enable function of the MIC4826 is implemented by

switching the RSW and REL resistor between ground

and VDD. When RSW and REL are connected to ground,

the switch and the EL oscillators are disabled; therefore

the EL driver becomes disabled. When these resistors

connect to VDD, both oscillators will function and the EL

driver is enabled.
