Product Overview
PAM8904EGPR is a piezo sounder driver with an 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. Applications include healthcare systems, alarm clocks, security devices, and home appliances.
- Integrated boost converter generates up to 13.5V supply
- No voltage cross output in shutdown mode
- Low current consumption
- Automatic standby and wake-up control
- Shutdown current is 0.008µA typ at DIN = 0V
- Output short-circuit current is 49mA typical
- Oscillating frequency is 130kHz maximum
- Shutdown delay time is 42ms typ at DIN = H- > L
- Operating free-air temperature range from -40 to +85°C
- W-QFN2020-12 (type US) package
