PAM8904

18VPP OUTPUT PIEZO SOUNDER DRIVER

Description

Pin Assignments

The PAM8904 is a piezo sounder driver with integrated charge pump

boost converter. The PAM8904 is capable of driving a ceramic/piezo

sounder with 24V_PPfrom a 5.5V power supply. The charge pump can

operate in either a 1x, 2x or 3x mode.

Pin 1

The boost converter operates at a fixed frequency of 1.0MHz and

provides

a 12V output with a minimum number of external

components. The PAM8904 can drive up to 15nF loading. Diodes

Incorporated’s unique drive technology provides a small inrush

current, low EMI and high efficiency.
