Подробное описание
The PAM8904E is a piezo sounder driver with integrated charge pump boost converter.
The PAM8904E is capable of driving a ceramic/piezo sounder with 27VPP from a 4.5V power supply. The charge pump can operate in either 1x, 2x or 3x mode.
The boost converter operates at a fixed frequency of 100kHz and provides a 3X VIN output with a minimum number of external components. The PAM8904E can drive up to 47nF loading. Diodes Incorporated’s unique drive technology provides a small inrush current, low EMI and high efficiency.
The PAM8904E includes built-in automatic shutdown and wake up that guarantees longer battery life. The PAM8904E features thermal shutdown, over current protection, over voltage protection and under voltage lock-out.
The PAM8904E is available in U-QFN3030-16 (Type B), U-QFN3030-12 (Type A) and W-QFN2020-12 (Type US) packages.
