STK672-040 Datasheet Microstep Operation-supported 4-phase Stepping Motor Driver (io= 1.5a)

Manufacturer: SANYO (now Panasonic)

Overview: 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.

Key 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.
  • Selectable vector locus (perfect circle mode, inside 1 mode, outside 2 modes) to match motor characteristics in microstep drive state.
  • Phase hold function during excitation switching.
