LV8491CT: Piezo Actuator Driver

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.

特性
  • 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.
  • 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.
