8.1 Application Information

This section details the information required to configure the TDZ8907 for several different applications and provides guidance on integrating the TDZ8907 into larger systems. The TDZ8907 can be used in any application that requires loud alerts/beeps/buzzes/tones using a piezoelectric sounder in a small footprint. The TDZ8907 design allows customers to drive 2-terminal piezo sounders using a single PWM input signal and the integrated boost, or with an external supply for the boost.
