Package Image

Package:ZIP23 (with heatsink)

2-phase stepper motor unipolar IC, self excitation PWM current control with fixed off time. The built-in current sense resistor allows reduction of external components. The series has a built-in protection function which operates during abnormal operation (motor coil opens/shorts ) and thermal shutdown protection as well. Lineup with various rated currents and are also available.
