bipolar stepper motor driver

CF2068D is a cost  effective, high performance bi-polar 2-phase micro-stepper drive applying  pure-sinusoidal current control technique. It is best suited for the applications that desired extreme low noise and heat. It operates well in an  environment where electricity supply experience instability and fluctuation.
The general  pure-sinusoidal current control technology adopted by majority of the drive  produced distorted sine wave, and current ripple, resulting in vibration, noise  and motor heating. This results in motor degrading over time, reducing in motor  performance and shortens the usage life.
With an automatic  optimization speed control technique, the power step series drive output is  very stable, with almost zero vibration and noise, performing close to a servo  system, allowing the motor to operate smoothly. That helps to fulfill a design  requirement of low noise, low heat and high performance.
