NSP2340BA24E is a multi-chip package (MCP) IC designed for voice assistance solutions. With a built-in buzzer driver, allowing a piezoelectric buzzer to play human voice and sound effects similar to a speaker. It communicates with microcontrollers via I2C/UART interface and features a built-in voltage booster to drive the piezo buzzer directly. NSP2340BA24E is equipped with a high-performance buzzer driver, with up to a 24-volt internal booster, over-current/over-voltage protection, automatic shutdown and wake-up control. The PlayList Editor provides high flexibility for loading pre-recorded messages and EQ adjustment tailored to piezo buzzer specifications. It is suitable for various applications in security, industrial, and white goods where beeping sounds and voice instructions are widely used.
