PIN ASSIGNMENTS
Pin 1 — ELEN1 — Electroluminescent Lamp
Enable 1. When driven HIGH, this input pin
enables the EL driver outputs for EL1 and
EL2. This pin has an internal pulldown
resistor.
Pin 2 — ELEN2 — Electroluminescent Lamp
Enable 2. When driven HIGH, this input pin
enables the EL driver outputs for EL3 and
EL4. This pin has an internal pulldown
resistor.
Pin 3 — R
— Oscillator Resistor. Connect-
ing a resistor between V
and this pin sets
the frequency of the internal clock.
Pin 4 — No Connect.
Pin 5 — No connect.
Pin 6 — No connect.
Pin 7 — V
— Power Supply Ground. Connect
to the lowest circuit potential, typically
ground.
Pin 8 — COIL — Coil. The inductor for the
boost converter is connected from V
BATT
to
this pin.
Pin 9 — CAP — Integrating Capacitor. An
integrating capacitor connected from this
pin to ground filters out any coil switching
spikes or ripple present in the output wave-
form to the EL lamps. Connecting a fast
recovery diode from COIL to CAP increases
the light output of the EL lamp.
Pin 10 — EL4 — Electroluminescent Lamp
Output 4. This is a high voltage lamp driver
output pin paired with EL3 to drive the EL2
lamp.
Pin 11 — EL3 — Electroluminescent Lamp
Output 3. This is a high voltage lamp driver
output pin paired with EL4 to drive the EL2
lamp.
Pin 12 — EL1 — Electroluminescent Lamp
Output 1. This is a high voltage lamp driver
output pin paired with EL2 to drive the EL1
lamp.
Pin 13 — EL2 — Electroluminescent Lamp
Output 2. This is a high voltage lamp driver
output pin paired with EL1 to drive the EL1
lamp.
Pin 14 — V
— Positive Power Supply. This
pin should be bypassed with a 0.1
μ
F capaci-
tor.
