Dual Electroluminescent Lamp Driver  
MAX514  
General Description  
Features  
The MAX14514 is a high-voltage DC-AC converter ideal  
for driving two electroluminescent (EL) lamps. The  
MAX14514 features a +2.7V to +5.5V input range that  
allows the device to accept a wide variety of voltage  
sources, including single-cell lithium-ion (Li+) batteries.

The MAX14514 utilizes an inductor-based boost con-  
verter to generate the high voltage necessary to drive EL  
lamps and allows the use of a 220µH inductor to effec-  
tively drive total combined lamp sizes of up to 20nF.

The MAX14514 uses a high-voltage full-bridge output  
stage to convert the high voltage generated by the  
boost converter to an AC waveform suitable for driving  
the EL panels. An external resistor controls the slew-  
rate of the rising and falling edges of the AC drive  
waveform to reduce audible noise output. The high-volt-  
age outputs are ESD protected up to 15ꢀV Human

The MAX14514 features dimming/enable controls  
(DꢁM1, DꢁM2) for each output to allow the user to set  
the peaꢀ-to-peaꢀ output voltage with a PWM signal, a  
DC analog voltage, or a resistor connected from DꢁM_  
to ꢃND. The MAX14514 also provides a slow turn-on/-  
off feature that slowly ramps the output voltage applied  
to the lamp when enabled or disabled.

The MAX14514 enters a low-power shutdown mode  
when the EN and DꢁM_ inputs are connected to ꢃND.  
The device also features thermal shutdown if the die  
temperature exceeds +158°C (typ).  
Pin Configuration  
The MAX14514 is available in a space-saving, 14-pin,  
3mm x 3mm TDFN pacꢀage and is specified over the  
extended -40°C to +85°C operating temperature range.
