LV8054LP
Bi-CMOS IC
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)

Sample Timing Chart for the Excitation Direction Setting
www.DataSheet4U.com
The excitation direction setting sets the excitation (rotation) direction of the stepping motor.
With the CW (clockwise) setting, the phase of the channel 2 current is delayed from that of the channel 1 current by 90°.
With the CCW (counterclockwise) setting, the phase of the channel 2 current leads that of the channel 1 current by 90°.
