PAM8904QJER

PAM8904Q AUTOMOTIVE 18VPP OUTPUT PEIZO SOUNDER DRIVER Pin Assignments The PAM8904Q is a piezo sounder driver designed for driving a ceramic/piezo sounder or speaker with 18VPP from a 3V power CPM1 NC CP1 GND DIN Features            CN2 NC VO2 VO1 CN1 NC To help protect the IC and system, the PAM8904Q includes overtemperature shutdown, overcurrent and short circuit protection. The PAM8904Q is qualified to AEC-Q100 Grade 2 and is Automotive Compliant supporting PPAPs. VOUT 1 CPM2 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. The PAM8904Q is available in a 16 pin U-QFN3030-16 (Type B) package. CP2 NC 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. VIN (Top View) supply. A programmable charge pump boost converter allows the PAM8904Q VOUT to operate in 1x, 2x and 3x mode.
