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
Ultra-small chip size package
Low ON-Resistance Power CMOS output
Built-in 15 MHz Oscillator (OSC)
2-wire serial interface (I2C BUS compatible)
1.8 V can be put into each control input terminal
Slew rate control function of output voltage
Standby current consumption 0 µA (Typ.)
●Applications
Auto focus of cell phone
Auto focus of Digital still camera
Camera Modules
Lens Auto focus
Web, Tablet and PC Cameras
