PIN ASSIGNMENTS
Pin 1 — CLK — Clock. Connect this input pin
to an external 32KHz clock sets the
frequency of the internal flip flops.
Pin 2 — V
— Power Supply Common.
Connect to the lowest circuit potential,
typically ground.
Pin 3 — EL2 — Eluminescent Lamp. This is
a lamp driver output pin to connect to the
EL lamp.
Pin 4 — COIL — Coil. The inductor for the
EL lamp is connected from V
BATTERY
to this
input pin.
Pin 5 — C
— Integrating Capacitor.
Connecting a fast recovery diode from
COIL (pin 4) to this input pin increases the
light output of the EL lamp. An integrating
capacitor (100pF) connected from this pin to
ground filters out any coil switching spikes
or ripple present in the output waveform to
the EL lamp.
Pin 6 — EL1 — Eluminescent Lamp. This is
a lamp driver output pin to connect to the
EL lamp.
Pin 7— V
— Positive Battery Power Supply.
Connect such that +2.2V < V
DD
< +4.5V.
Pin 8 — ELEN — Eluminescent Lamp Enable.
When driven HIGH, this input pin enables
the EL driver output EL1 and EL2 (pins 6 and
3, respectively) to the EL lamp.
