The NJW4351 is a high efficiency DMOS unipolar stepper motor driver IC. Compared to previous devices, it is more suitable for low voltage operation, capable of handling 5.0V, 3.3V and the like logic circuits. Drive Stage consists of DMOS which produces high efficiency and low heat generation motor drive circuit. The motor can be controlled by the STEP and DIR system. Further more, to improve controllability of system, MO, ENABLE, RESET and PD function are included, various applications are possible.
