LV8491CT  
Piezo Actuator Driver IC  
Overview  
The LV8491CT is a piezoelectric actuator driver IC. It internally generates drive waveforms and this makes it possible  
to control piezoelectric actuators with simple instructions.  
Features  
• Actuators using piezoelectric elements can be driven and controlled simply by I2C communication.  
• Multiple patterns of drive waveform conditions can be set for before and after performing normal operation when  
executing the DRVPULSE instruction.  
• The piezoelectric drive waveforms are set externally by serial input signals using the I2C interface.  
The rising and falling timings are determined with clock count.  
• Startup/stop of the IC is controlled by ENIN register input through I2C communication.  
• The time for which the actuator is driven is determined with the drive frequency setting based on I2C communication.  
• BUSY output can be used to identify the operation/stop state of the actuator while output is present at the OUT pin.  
The BUSY signal can also be checked with the READ function controlled through I2C communication.  
• Built-in undervoltage detection and protection circuit, and register power-on reset function.
