STK672-010 Datasheet | SANYO

Ordering number : EN4927 Thick-Film Hybrid IC Unipolar Fixed-Current Chopper (separate excitation) Type 1.7 A Output Current Stepping Motor Driver with Built-in 4-Phase Distribution Controller Overview The STK672-010 is a 4-phase stepping motor driver IC that adopts power MOSFET for its output stage and that uses a unipolar fixed-current chopper scheme. Since the STK672-010 includes a built-in 4-phase distribution controller, the stepping motor driver circuit and the control scheme can be simplified, and the stepping motor driver circuit structure can be standardized. The STK672-010 provides high torque, low vibration, and rapid response based on a W1-2 phase excitation drive...
