LB1940T:2-Channel H-Bridge Constant Current Driver
The LB1940T and LB1940U are 2-phase exciter type bipolar stepping motor driver ICs that feature low-voltage (supporting 3V battery) and low current operation with low saturation voltage. These ICs enable constant-current control of actuators and are optimal for driving the actuators of PC peripherals such as USB compatible scanners and printers. Other target applications include controlling the shutter, iris and AF of digital still cameras.
