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 and Features

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

• Ultraminiature package (MSOP8: 150 mil)

• Built-in thermal protection circuit

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

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