LV8071LP - Piezoelectric Actuator Driver IC

Description

of the Operation

CLK1 and CLK2 inputs CLK1 incorporates the quarter-dividing circuit.

To input 39MHz directly, input it directly to the CLK1 pin.

When the dividing circuit is provided externally, input 9.75MHz to the CLK2 pin.

1 cycle: One

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 acco.

Ordering number : 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. 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.
