PIN ASSIGNMENTS
Pin 1 — ELEN — Eluminescent Lamp Enable.
When driven HIGH, this input pin enables
the EL driver output EL1 and EL2 (pins 4 and
5, respectively) to the EL lamp.
Pin 2 — V
— Power Supply Common.
Connect to the lowest circuit potential,
typically ground.
Pin 3 — COIL — Coil. The inductor for the
EL lamp is connected from V
BATTERY
to this
input pin.
Pin 4 — EL1 — Eluminescent Lamp. This is
a lamp driver output pin to connect to the
EL lamp.
Pin 5 — EL2 — Eluminescent Lamp. This is
a lamp driver output pin to connect to the
EL lamp.
Pin 6 — V
— Positive Battery Power Supply.
Connect such that +2.2V < V
DD
< +4.5V.
Pin 7 — C
— Integrating Capacitor.
Connecting a fast recovery diode from
COIL (pin 3) to this input pin increases
the light output of the EL lamp. An
integrating capacitor (0.1
μ
F) connected
from this pin to ground filters out any coil
switching spikes or ripple present in the
output waveform to the EL lamp.
Pin 8 — R
OSC
— Oscillator Resistor. Connecting
a 450k
resistor to this input pin sets the
frequency of the internal clock.
