LV8071LP Overview
ENA0991 LV8071LP Overview Bi-CMOS IC Piezoelectric Actuator Driver IC 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.
LV8071LP Key Features
- The 39MHz (CLK1 pin input) CLK input is divided into quarters internally to generate the 9.75MHz input. The operation ti
- 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
