SP4501 General Description

The SP4501 provides designers with both an electroluminescent lamp driver for backlighting and 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 1mA (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 V_DD and V_SS.
