Overview
Monolithic Digital IC
2-ch 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 patible scanners, FDDs, and printers, as well as for controlling the shutter, iris, and AF of a digital still camera.
Features
- Low-voltage driving 2-power source type: VS = 1.6 to 7.5V, VDD = 1.9 to 6.5V Single power source type: VS = VDD = 1.9 to 7.5V
- Low saturation output: VO(sat) = 0.3V at IO of 200m A
- Constant-current control
- Built-in reference voltage (Vref = 0.9V)
- Small-sized, low-profile package (LB1940T: TSSOP20; 225mil; thickness (t) = 1.2mm max.) (LB1940U: MSOP20; thickness (t) = 0.85mm max.)
