Package : HSOP44
RoHS : YES
2-phase stepper motor unipolar driver IC. The product has self-excitation PWM current control with fixed off time, with built-in protection features which operates during abnormal motor operation (coil short & open). Use of surface mount package allows the product to be mounted with 1/2 hight, compared to conventional packages(SLA,STA)
