Datasheet
Piezoelectric Actuator Driver
BU64562GWZ
●General Description
The BU64562GWZ is designed to drive Piezo motors for
camera auto focus.
It has an integrated D/A converter for setting the output
voltage.
This lens driver includes the slope sequence to reduce
the driving noise of Piezo actuator.
The functional lens system can be controlled through
2-wire serial interface (I²C BUS compatible).
●Features
