The DiodesZetex makes piezo sounder driver with integrated boost switch, power diodes, and fully differential amplifier. This versatile device is capable of driving piezo sounder for a variety of applications, including location tracker, air humidifier or haptic feedback related applications. The PAM8907 supports selectable boost voltage output by VSET pin for low/high voltage output. A typical start-up time of 1.1ms makes the PAM8907 an ideal piezo driver with fast response. The device has built-in thermal overload protection, current limit and various protection features to prevent the device from damage when overdriven.

Supply voltage range from 1.8V to 5.5V It has an intergraded Boost converter with VOUT of 11V or 15.6V Drive Piezo Sounder with up to 31VPP, with high-speed driver designed with very short turn-on/turn-off No voltage Cross Output at Shutdown mode and high impendence output at Shutdown mode Low current consumption, with Shutdown current less than 1μA Space saving device with automatic Shutdown and Wake-up control
