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.
