For Digital Cameras
Single-chip motor Driver IC
Overview
LV8054LP is single-chip motor driver IC for digital cameras.
Functions
• Integrates the digital camera actuator drivers on a single chip
• Four constant voltage output channels, two constant current output channels
• All actuators can be driven at the same time
• The AF and zoom stepping motors are driven by the clock signal
• Supports PWM control of a DC zoom motor.
• Can switch between an external input or an internal reference for the constant voltage output setting reference voltage
• The constant voltage output multiplier can be set to one of 16 levels
• The constant current output reference voltage can be set to one of 16 internal reference voltage levels
• Built-in photosensor drive transistor
• Three built-in Schmitt buffer circuits (the presence or absence of hysteresis can be set individually)
