Digital Still Camera for Exposure/Shutter/
Focus/Zoom Motor Driving
The APX6223 CMOS integrated circuit builds driving
capability for Digital Still Camera Exposure/Shutter/
Focus/Zoom motor operation. Independent control
inputs drive Saturation, Constant voltage and Constant
current H bridge.
Advanced CMOS processing is used to take advantage
of low-voltage and low-power requirements. A power
saving mood can optimize the energy saving in portable
application. The APX6223 comes in a miniature 48-pin
LQFP and TQFN packages.
