LB1940T
LB1940U
Overview
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, 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 200mA
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.)
