STK672-040 Datasheet (Sanyo Semicon Device) - Microstep Operation-Supported 4-Phase Stepping Motor Driver (Io= 1.5A)

STK672-040, Microstep Operation-Supported 4-Phase Stepping Motor Driver (Io= 1.5A)

Ordering number: EN 5227A Thick Film Hybrid IC STK672-040 Microstep Operation-Supported 4-Phase Stepping Motor Driver (IO = 1.5A) Overview The STK672-040 is a unipolar constant-current choppertype externally-excited 4-phase stepping motor driver hybrid IC which uses MOSFET power devices.

It has a microstep operation-supported 4-phase distributed controller built-in to realize a high torque, low vibration, low noise stepping motor driver using a simple control circuit.
