1. Introduction
Adopting the chip manufactured by Japan Sanyo, DD8727T4V1 is a high sub-division two- phase step motor driver developed by many times’ optimization, which is suitable to drive the small and medium phase(the two or four phase current lower than 4A) hybrid step motor. Comparing with other driving mode, the new style bipolar constant current chopping driving technology enables the DD8727T4V1 output higher speed and power when you use the same motor. Its sub-division feature improves the motor operating accuracy, decreases the shaking and reduces the noise.
