SP4501 EL Plus Piezo Driver

SP4501 Description

® SP4501 EL Plus Piezo Driver s Integrated EL Plus Piezo Driver For Portable Electronic Devices s Reduces System Cost, Size & Component Count s +2.2V.
The SP4501 provides designers with both an electroluminescent lamp driver for backlighting and a piezotransducer driver to generate audio alert tones.

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
