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
