Piezoelectric Actuator Driver IC
Overview
The LV8071LP is a piezoelectric autofocus actuator driver IC for use in cell phone cameras. It internally generates drive
waveforms, which reduces DSP load and makes it possible to control piezoelectric actuators by simple control signals.
Features
The actuator using the piezoelectric device is driven by the external CLK input and simple control signal.
The 39MHz (CLK1 pin input) CLK input is divided into quarters internally to generate the 9.75MHz input.
The operation time is generated using this as a base CLK to ensure the output appropriate for piezoelectric drive.
The CLK2 input of 9.75MHz is input to be used, as it is, for the base CLK either.
IC start/stop is controlled by the EN input. Initialization is made according to the built-in sequence at startup.
The actuator drive time is determined by inputting the pulse to the DRIVE pin.
To recognize operation/stop of the actuator, the BUSY signal is output while the OUT pin performs any output.
