It also features thermal shutdown protection, over-current protection, over-voltage protection and under-voltage-lockout protection to assure safe system operation. Low Supply Current and Output Impedance -40 to +85Operating Temperature Range Available in Green TSSOP-16 (Exposed Pad) and TDFN-3×3-14L Packages. The PAM8907 has built-in automatic shutdown and wake-up functions for longer operating lifetime requirement. 12 month limited warranty view Terms & Conditions for details. Correction: Make sure to connect the pin4 of the IC 555 with the positive supply line. ![]() It simply works with two integrated circuits and very few parts. The circuit illustrated below generates sounds similar to a genuine buzzer. Transducer Function: Buzzer Supply Voltage Min: 3V Supply Voltage Max: 30V. Multicomp Pro products are rated 4.6 out of 5 stars. PZ1 Piezo element, 27mm, three terminal Rubber ring 22mm Simple Buzzer using 8 Ohm Speaker. A passive buzzer needs a driver and can generate sound at different pitches. PAM8907 Boost converter output can be set to either 11V or 15.6V with minimum external components for various application usages. The MCABT-458-RC is a 1mA/25V Piezo Transducer Sounder with LCP housing, surface mount, single tone, 75dB sound level and 4kHz resonant frequency. The charge-pump boost converter operates at a fixed frequency of 100 kHz and provides a 9 V output with a minimal. It features a charge pump that boosts in either 1X, 2X, or 3X modes. With integrated boost converter and unique piezo sounder driver technology, the PAM8907 provides small inrush current, low EMI and yet highly efficient system performance. Diodes’ PAM8904E piezo sounder driver with an integrated charge-pump boost converter can drive a ceramic/piezo sounder with 27 V PP from a 4.5 V power supply. The PAM8907 integrates a boost converter that operates at a typical frequency of 1.8MHz. The PAM8907 provides clear benefits for battery-operated tracker, piezoelectric horn or alarm related applications. With integrated boost converter, the PAM8907 can provide an optimized solution with higher Sound Pressure Level (SPL) for louder output sound, lower quiescent current for longer standby time, and auto turn-on/off feature for extended operating lifetime. The PAM8906 is available in MSOP-10 package for smaller PCB footprint and higher SMT yield.The PAM8907 is a piezoelectric horn driver with built-in boost converter, capable of driving a ceramic/piezo sounder with up to 31V PP output. Farnell UK offers fast quotes, same day dispatch, fast delivery, wide inventory, datasheets & technical support. It also features thermal shutdown protection, over-current protection, over-voltage protection and under-voltage-lockout protection to ensure safe system operation. The PAM8906 can operate with an external PWM input or operate in self-excitation mode (only 10V and 12V supported in this mode) for various piezo sounder applications. The PAM8906 comes in three different Output Voltage (V OUT) options: 10V, 12V, and 18V. The operating voltage of NJW1280 is 2.0V to 5.5V, and it can. ![]() The integrated boost converter switches at a fixed frequency of 1.8MHz and as a result, it can operate with a small 0.47µH inductor. supply, and can be configure a large-capacity 30nF piezo-sounder with four external capacitors. With the integrated boost converter and unique piezo sounder driver technology, PAM8906 provides small inrush current, low EMI and yet delivers high system efficiency. PAM8906 provides clear benefits for battery-operated piezoelectric sounder or alarm related applications. With integrated boost converter, the PAM8906 can provide an optimized solution with higher Sound Pressure Level (SPL) for louder output sound, and lower quiescent current along with auto turn-on/off feature for extended battery runtime. The PAM8906 is a piezoelectric sounder driver with built-in boost converter, capable of driving a piezo sounder with up to 36V PP output. ![]()
