These comprise thermal shutdown, over-current, over-voltage and under-voltage lock-out protection. Product reliability is aided by the PAM8904’s low inrush current, low EMI drive technology and a variety of integrated protection features. In shutdown mode, quiescent current is less than 1♚. For example, active current consumption is just 300♚ in 1x mode, with an input voltage of 3V, input frequency of 4kHz and driving a 15nF piezo. The sounder driver helps to keep current consumption low and battery life long by employing built-in automatic shutdown and wake-up functions. The charge pump also enables designers to select three different piezo sound pressure levels by offering 1x, 2x and 3x operating modes. Operating from a 2.3V to 5.5V supply at a fixed frequency of 1MHz, the PAM8904 is able to drive a sounder load of up to 15nF, providing a 9V output with a minimal component footprint. With its wide input signal range of 20Hz to 300kHz and ability to deliver high volume at a low operating current, this driver is suitable for a variety of battery-powered applications, including medical systems, alarm clocks and security devices. The PAM8904 is capable of driving piezoelectric sounders up to 18V PP from a 3V power supply. 5, 2014- Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced the PAM8904 piezo-sounder driver with integrated multi-mode charge pump boost converter. These comprise thermal shutdown, over current, over voltage and under voltage lock-out protection.PLANO, Texas-(BUSINESS WIRE)-Jun.
