SP4501, EL Plus Piezo Driver
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 com

SP4501 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
