Package : ZIP15

RoHS : YES

2-phase stepper motor unipolar IC, self excitation PWM current control with fixed off time. The built-in current sense resistor allows reduction in external components compared to the existing product. Also includes protection circuits which operates during abnormal motor operation (coil short & open) (Please refer to the application note for details.) Line up with different current outputs and sequencers are also available.
