PIN ASSIGNMENTS
Pin 1 — ELEN — Electroluminescent 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
BATT
to this
input pin.
Pin 4 — EL1 — Electroluminescent Lamp. This
is a lamp driver output pin to connect to the
EL lamp.
Pin 5 — EL2 — Electroluminescent 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
— Integrator Capacitor.
An Integrator Capacitor (470pF typical)
connected from this pin to ground filters out
any coil switching spikes or ripple present
in the outer waveform to the EL lamp.
Connecting a fast recovery diode from
COIL (pin 3) to this input pin increases the
light output of the EL lamp.
Pin 8 — R
OSC
— Oscillator Resistor. Connecting
a 450k
resistor to this input pin sets the
frequency of the internal clock.
