MAS6253 – 40Vpp Piezo Driver IC for Multi-Tone Sound
Micro Analog Systems Oy introduces piezo driver IC in a small DFN-10 2x2x0.5 mm package. It is a high efficiency, easy to use and low cost solution for piezo sound applications requiring high sound pressure level (SPL). Typical applications include piezo buzzers, alarm devices, white goods and handheld or portable devices with sound feature.
The heart of the IC is a high efficiency synchronous boost DC/DC converter requiring only a small 0806 sized 2.2H inductor. The output voltage is regulated and adjustable up to 20V either in pin mode or via I2C bus. The bridge-tied load (BTL) output of the piezo driver is capable of driving up to 40Vpp signal in a very wide supply voltage range from 1.6V to 5.5V.
The MAS6253 is available in DFN-10 2x2x0.5 mm package. Samples are available. Price for a DFN packaged device is USD 0.8 (3 000 pcs). For further information and samples, please contact Micro Analog Systems Oy at info-mas@mas-oy.com
