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 (I
O
= 400 mA when R
f
= 0.5
)
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)
