STK673-011-E

MOTOR DRIVER, STEPPER, 2.4A, SIP-28.

The STK673-011-E is a 3-phase stepping motor driver Hybrid IC with built-in microstep controller having a bipolar constant current PWM system, in which a power MOSFET is employed at an output stage. It includes a 3-phase distributed controller for a 3-phase stepping motor to realize a simple configuration of the motor driver circuit. The number of motor revolution can be controlled by the frequency of external clock input. The basic step angle of the stepping motor can be separated as much as one-eighth 2 to 3-phase to 2W 2 to 3-phase excitation mode control quasi-sine wave current, thereby realizing low vibration and low noise.
