[ Alternative : SLA7078MPRT]
STA7133MC
Package:ZIP18
2-phase stepper motor unipolar IC, self excitation PWM current control with fixed off time.
It is enclosed in a compact ZIP package (STA), while having equivalent features as the conventional product (SLA7070MPRT series).
This allows reduction of external components and PCB size.
Lineup with various rated currents are available.
Features
