LB1941T
Constant Current Forward/Reverse Driver IC
for Digital Cameras
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)
