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. Package Dimensions unit.

STK672-040 Features

* Microstep sine-wave driver operation using only an external clock input (0.33Ω current detection resistor built-in)

* Microstep drive using only an external reference voltage setting resistor

* 2, 1-2, W1-2, 2W1-2, 4W1-2 phase excitation selectable using external pins
