PAM8904QJER Piezo Sounder Driver U-QFN3030-16 (Type B) Surface Mount
Description
The PAM8904Q is a piezo sounder driver designed for driving a ceramic/piezo sounder or speaker with 18VPP from a 3V power supply. A programmable charge pump boost converter allows the PAM8904Q VOUT to operate in 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. 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.
The PAM8904Q is available in a 16 pin U-QFN3030-16 (Type B) package.
The PAM8904Q is qualified to AEC-Q100 Grade 2 and is Automotive Compliant supporting PPAPs.
