LB1941T

Overview

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.

Functions

• Constant current control (IO = 400mA when Rf = 0.5Ω)

• Ultraminiature package (MSOP8: 150mil)

• Built-in thermal protection circuit

• Includes a rapid charge/rapid discharge circuit for stable shutter operation.

• Built-in reference voltage circuit (0.2V typical)
