Constant Current Source for SMA (CB1244E)

    In the figure we have a constant current source for Shape Memory Alloy or (Nitinol). The value of R is calculated by dividing 1.25 by the desired current. The integrated circuit used can control up to 3 A and must be fitted with a heat radiator. The circuit is from the book Mechatronics Sourcebook by Newton C. Braga, published in the United States.
