18VPP OUTPUT PEIZO SOUNDER DRIVER

No Preview Available !

Description
The PAM8904 is a piezo sounder driver with integrated a charge
pump boost converter. The PAM8904 is capable for driving a
ceramic/piezo sounder with 18Vpp from a 3V power supply. The
charge pump can operate in either of a 1X, 2X and 3X mode.
The boost converter operates at a fixed frequency of 1.0MHz and
provides a 9V output with a minimum number of external
components. The PAM8904 can drive up to 15nF loading. PAM
unique drive technology provides small inrush current, low EMI and
high efficiency.
PAM8904 built-in automatic shutdown and wake up that guarantees
longer battery life.
PAM8904 features thermal shutdown, over current protection, over
voltage protection and under voltage lock-out.
The PAM8904 is available in a 16pin U-QFN3030 package.
