Monolithic Linear IC
Overview
For Digital Cameras
Constant Current Forward/Reverse Driver
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.
Functions
- High-performance dual operational amplifier
- Constant current control (IO = 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)
