LB8681CL 
Overview
The LB8681CL is a low-voltage, low-saturation 1.5-channel constant current forward/reverse driver IC provided in a 
miniature package suitable for use in cell phone cameras. The LB8681CL can be driven directly from a microcontroller 
and is optimal for control of the voice coil motors used for shutter and aperture control in cell phone cameras. 
Features 
 Supports low-voltage drive. (2.2V or more) 
 Ultraminiature package (ECSP2828-10) 
Functions 
 Constant current control (IOUT = 100mA at RF = 2
Ω
) 
 Built-in thermal protection circuit 
 Built-in reference voltage (0.2V typical)
