The LB1941GP 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.

• High-performance dual operational amplifier

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

• 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)

• Ultraminiature package (VCT16 (2.6mm × 2.6mm)
