PAM8904Q

AUTOMOTIVE 18VPP OUTPUT PEIZO SOUNDER DRIVER

Description

Pin Assignments

The PAM8904Q is a piezo sounder driver designed for driving a

ceramic/piezo sounder or speaker with 18V_PPfrom a 3V power

supply. A programmable charge pump boost converter allows the

PAM8904Q V_OUTto operate in 1x, 2x and 3x mode.

(Top View)

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

CPM₂

D_IN

provides

a 9V output with a minimum number of external

components. PAMs unique drive technology ensures minimal inrush

current, low EMI and high efficiency.

To ensure maximum efficiency and battery life, the PAM8904Q

includes an auto standby feature which puts the device in sleep mode

while there is no valid input signal. A forced shutdown is also

available to enable the IC only when required.

To help protect the IC and system, the PAM8904Q includes

overtemperature shutdown, overcurrent and short circuit protection.

U-QFN3030-16 (Type B)

The PAM8904Q is available in a 16 pin U-QFN3030-16 (Type B)

package.

Applications
