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.
