Monolithic Digital IC  
LB1941T  
Constant Current Forward/Reverse Driver IC  
for Digital Cameras  
Overview  
Package Dimensions  
The LB1941T is a single-channel forward/reverse driver  
IC that provides a constant current control function. Its  
low-saturation output makes it appropriate for voice coil  
motor control, and it is optimal for use as the shutter  
driver IC in digital cameras.
