Integrated Circuits PAM8904EGPR Chip In Stock

18VPP OUTPUT PIEZO SOUNDER DRIVER

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, overcurrent protection, overvoltage protection and
undervoltage lockout.
The PAM8904E is available in U-QFN3030-16 (Type B), U-QFN3030-
12 (Type A), W-QFN2020-12 (Type US) and U-QFN2020-12 (Type
UX) packages.
