EL Frequency
The EL lamp frequency is controlled via an external resistor
connected between REL pin and VDD pin of the device. As
the lamp frequency increases, the resistor value decreases.
For resistor value selections, see the
“
Typical
Characteristics: EL Frequency vs. EL Resistor
”
or use the
equation below. The EL frequency range is 60Hz to 1000Hz,
with an accuracy of
±
20%.

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 fre-
quency.

Enable Function
The enable function of the MIC4826 is implemented by
switching the R
SW
and R
EL
resistor between ground and V
DD
.
When R
SW
and R
EL
are connected to ground, the switch and
the EL oscillators are disabled; therefore the EL driver be-
comes disabled. When these resistors connect to V
DD
, both
oscillators will function and the EL driver is enabled.
