Product details

Description

The SP4501 provides designers with both an electroluminescent lamp driver for backlighting and a piezotransducer driver to generate audio alert tones.

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.
