DESCRIPTION
TheSP4501providesdesignerswithbothanelectroluminescentlampdriverforbacklightingand
a piezotransducer driver to generate audio alert tones. The integration of an EL lamp driver and
a piezotransducer driver in a single cost-effective IC reduces system cost, board space
requirements and component count. The SP4501 is ideal for portable applications such as
pagers, electronic games, PDAs, medical equipment, and designs with liquid crystal displays,
keypads, and backlit readouts. The SP4501 will operate from a +2.2V to +6.0V source. The
device features a low power standby mode which draws less than 1µA (typical). The frequency
of the internal oscillator is set with a single external resistor. The piezotranducer driver can be
driven with the internally generated clock signal or an external clock signal provided by the
designer. A single inductor is required to generate the high voltage AC used to drive the EL lamp
and the piezotransducer. All input pins are ESD protected with diodes to VDD and VSS.

Electroluminescent Technology
The internal diode forward biases when the coil
voltagerises abovetheH-Bridgevoltageandthe
energy enters the EL lamp. Each pulse increases
the voltage across the lamp in discrete steps.
An EL lamp consists of a thin layer of phospho-
rous material sandwiched between two strips of
plastic which emits light (flouresces) when a
high voltage AC signal is applied across it. It
behaves primarily as a capacitive load. Long
periods of DC voltage applied to the material
tendtoreduceitslifetime. Withtheseconditions
in mind, the ideal signal to drive an EL lamp is a
high voltage sine wave. Traditional approaches
toachievethistypeofwaveformincludediscrete
circuits incorporating a transformer, transistors
and several resistors and capacitors. This ap-
proach is large and bulky and cannot be imple-
mented in most handheld equipment. Sipex
offers low power single chip driver circuits spe-
cificallydesignedtodrivesmalltomediumsized
electroluminescent panels. Sipex EL drivers
provide a differential AC voltage without a DC
offset to maximize EL lamp lifetime. The only
additionalcomponentsrequiredfortheELdriver
circuitry are an inductor, resistor and capacitor.
As the voltage approaches its maximum, the
steps become smaller. (see figure 4).
The brightness of the EL lamp output is directly
relatedtoenergyrecoveryintheboostconverter.
There are many variations among coils such as
magnetic core differences, winding differences
and parasitic capacitances. For suggested coil
suppliers refer to page 10.
Oscillator
Theinternaloscillatorgeneratesahighfrequency
clock used by the boost converter and H-Bridge.
An external resistor from VDD to ROSC sets the
oscillatorfrequency. Typicallya500kΩresistor
sets the frequency to 45.7kHz. The high fre-
quency clock directly controls the coil switch.
This high frequency clock is divided by 128 to
generate a low frequency clock which controls
the EL H-Bridge and sets the EL lamp fre-
quency. The high frequency clock is divided by
16 to create a medium frequency clock to drive
the piezo H-Bridge. The oscillator has low
sensitivity to temperature and supply voltage
variations, increasing the performance of the EL
driver over the operating parameters.
Electroluminescent backlighting is ideal when
used with LCD displays, keypads or other back-
lit readouts. EL lamps uniformly light an area
without creating any undesirable "hot spots" in
the display. Also, an EL lamp typically con-
sumes less power that LED's or incandescent
bulbs in similar lighting situations. These fea-
tures make EL ideal for attractive, battery pow-
ered products.
Dual H-Bridge
The H-Bridge consists of two SCR structures
and two NPN transistors that control how the
lamp is charged. Setting ELEN to HIGH acti-
vates the EL H-Bridge. The EL driver illumi-
nates the lamp by applying the high voltage
supply of the boost converter to the lamp termi-
nals through the H-Bridge and then switching
the terminal polarity between the high voltage
supply and ground at a constant frequency. This
applies an AC voltage to the lamp that is twice
the peak output voltage of the boost driver. An
AC voltage greater than the 40V across the
terminals of the lamp is necessary to adequately
illuminate the EL lamp. The piezo driver output
applies an AC voltage to the piezotransducer in
a similar manner. The piezo driver operates in
two modes.
THEORY OF OPERATION
Coil Switch
The SP4501 has an inductor-based boost con-
verter to generate the high voltage used to drive
the EL lamp. Energy is stored in the inductor
2
according to the equation EL = 1/2 (LIpk ) where
Ipk = (tON) (VBATT - VCEsat) /L. An internal oscilla-
tor controls the coil switch. During the time the
coil switch is on, the coil is connected between
VDD and the saturation voltage of the coil switch
and a magnetic field develops in the coil. When
the coil switch turns off, the switch opens, the
magnetic field collapses and the voltage across
the coil rises.

AlogicHIGHonpinPZENwillenablethepiezo
driver and apply a waveform to the
piezotransducer until PZEN is released. This
waveform will produce a tone that is 1/16 the
frequency of the internal oscillator. Alternately,
anexternalclockappliedtoPZCKorPZCKpins
will enable the piezo driver and generate a tone
at the applied clock frequency.
Larger lamps require more energy to illuminate.
Lowering the oscillator frequency allows more
energy to be stored in the coil during each coil
switch cycle and increases lamp brightness. The
oscillator frequency can be lowered to a point
where the lamp brightness then begins to drop
because the lamp frequency must be above a
criticalfrequency(approx.100Hz)tolight. Lamp
color is affected by the switching frequency of
the EL driver. Green EL lamps will emit a more
blue light as EL lamp frequency increases.
The external applied clock frequency should be
greater than fosc/64. To put the circuit in an
inactive state it is required that PZCK remain at
logic LOW and PZCK remain at logic HIGH.
The piezo driver and the EL driver may be
operatedsimultaneouslybutwithdecreasedlight
output from the EL panel.
Noise Decoupling on Logic Inputs
If ELEN, PZEN, PZCK or PZCK are connected
totracessusceptibletonoise,itmaybenecessary
to connect bypass capacitors of approximately
10nF between ELEN and VSS, PZEN and VSS,
PZCK and VSS, and PZCK and VDD. If these
inputs are driven by a microprocessor which
provides a low impedance HIGH and LOW
signal, then noise bypassing may not be neces-
sary. If some inputs are unused (as PZCK and
PZCK may be) then these inputs should be tied
to the power supply that sets the input to an
inactive state.
DESIGN CONSIDERATIONS
Inductor Selection
If limiting peak current draw from the power
supply is important, small coil values (<1mH)
mayneedahigheroscillatorfrequency. Inductor
current ramps faster in a lower inductance coil
than a higher inductance coil for a given coil
switch on time period, resulting in higher peak
coil currents.
Increasing Light Output
EL lamp light output can be improved by con-
necting a fast recovery diode from the COIL pin
to the CAP pin. The internal diode is bypassed
resulting in an increase in light output at the EL
lamp. We suggest a fast recovery diode such as
the industry standard 1N4148.
It is important to observe the saturation current
rating of a coil. When this current is exceeded,
the coil is incapable of storing any more energy
andthenceasestoactasaninductor. Instead, the
coil behaves according to its series DC resis-
tance. Sincesmallcoils(<1mH)haveinherently
low series DC resistance, the current can peak
dramatically through a small coil during satura-
tion. This situation results in wasted energy not
stored in the magnetics of the coil but expressed
as heating which could lead to failure of the coil.
TheoptimalvalueofCINT willvarydependingon
the lamp parameters and coil value. Lower CINT
values can decrease average supply current but
higher CINT values can increase lamp brightness.
This is best determined by experimentation. A
rule of thumb is larger coils (1mH) are paired
with a smaller CINT (680pF) and smaller coils
(470µH) are paired with a larger CINT (1800pF).
Generally, selecting a coil with lower series DC
resistance will result in a system with higher
efficiency and lamp brightness.

Lamp Effects
EL lamp parameters vary between manufactur-
ers. Series DC resistance, lighting efficiency
and lamp capacitance per area differ the most
overall.
Designers can alter the sawtooth output voltage
waveformtotheELlamp. Increasingthecapaci-
tance of the integration capacitor, CINT, will inte-
grate the sawtooth waveform making it

appear more like a square wave.
Printed Circuit Board Layout Sugges-
tions
TheELdriver'shigh-frequencyoperationmakes
PCB layout important for minimizing electrical
noise. Keep the IC's GND pin and the ground
leads of C1 and CINT less than 0.2in (5mm) apart.
Also keep the connections to the COIL pin as
short as possible. To maximize output power
and efficiency and minimize output ripple volt-
age, use a ground plane and solder the IC's VSS
pin directly to the ground plane.
EL Lamp Driver Design Challenges
There are many variables which can be opti-
mized for specific applications. The amount of
light emitted is a function of the voltage applied
tothelamp,thefrequencyatwhichisapplied,the
lamp material, the lamp size, and the inductor
used. Sipex supplies characterization charts to
aid the designer in selecting the optimum circuit
configuration.
Sipex will perform customer application evalu-
ations, using the customer's actual EL lamp to
determine the optimum operating conditions for
specific applications. For customers consider-
inganELbacklightingsolutionforthefirsttime,
Sipex is able to provide retrofits to non-backlit

PIN ASSIGNMENTS
Pin 7 — VSS — Power Supply Ground. Connect
to the lowest circuit potential, typically ground
Pin 1 — ELEN — Electroluminescent Lamp
Enable. When driven HIGH, this input pin
enables the EL driver outputs. This pin has
an internal pulldown resistor.
Pin 8 — COIL — Coil. The inductor for the
boost converter is connected from VBATT to
this pin.
Pin2—PZEN—PiezoEnable. Whenthisinput
pin is driven HIGH, the piezo operates at a
frequency fOSC/16. When this input pin is
LOW, the clock signals applied to PZCK or
PZCK will drive the internal piezo circuitry.
This pin has an internal pulldown resistor.
Pin 9 — CAP — Integrator Capacitor. An
integrator capacitor connected from this pin

diode from COIL to CAP increases the light
output of the EL lamp.
Pin3—ROSC —OscillatorResistor. Connecting
a resistor between this pin and VDD sets the
frequency of the internal clock.
Pin 10 — PZ1 — Piezotransducer Output. Con-
nect this pin to the piezotransducer.
Pin 4 — PZCK — Inverse Piezo Clock. When
PZEN is LOW, the internal piezo circuit will
operate at the frequency of the clock signal
appliedtothisinput pin. Forthe piezodriver
