The MAS6241 is a piezo driver IC is a high efficiency, easy to use and low cost solution for piezo sound applications requiring a high sound pressure level (SPL). Typical applications include piezo buzzer, alarm devices, white goods and handheld or portable devices with sound feature.

It is an inductor free low EMI solution for achieving high sound pressure level (SPL). It includes a high efficiency 3x mode charge pump to boost input voltage to a high level. It can operate from a low supply voltage down to 2.2V and over a wide temperature range from -40°C to +125°C.

The MAS6241 is available in a QFN-12 3x3x0.75 mm package offering small size and low profile solution for driving piezoelectric sounder.
