Overview
The LV8094CT 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.
• 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.
• ENIN input that controls the startup/stop of the IC.
• The time for which the actuator is driven is determined with the drive frequency setting based on I²C communication.
• Provides a busy signal output during periods when the actuator is being driven by OUT pin output so that applications
can be aware of the actuator operating/stopped state.
• Built-in undervoltage protection circuits, and register power-on reset function.
