Overview
LV8048CS is single-chip motor driver IC for digital still cameras.
Features
• The actuator driver for DSC is built into single-chip.
• Two 256-division microstep output channel, and two constant current output channels
• All actuators can be driven at the same time
• AF / ZOOM stepping motor is driven by the clock signal
• Supports PWM control of a DC zoom motor
• The constant current output reference voltage can be set to one of 16 internal reference voltage levels (motor holding
current switching possible).
• Two photosensor drive transistor channels
• Two Schmitt buffer channels (the presence or absence of hysteresis can be set individually).
