Thick Film Hybrid IC
Microstep Operation-Supported
4-Phase Stepping Motor Driver (IO = 3.0A)
Overview
The STK672-050 is a unipolar constant-current chopper-
type externally-excited 4-phase stepping motor driver
hybrid IC which uses MOSFET power devices. It has a
microstep operation-supported 4-phase distributed con-
troller built-in to realize a high torque, low vibration, low
noise stepping motor driver using a simple control circuit.
Applications
• Printer, copier, and X-Y plotter stepping motor drivers
Features
• Microstep sine-wave driver operation using only an
external clock input (0.2
Ω 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
• Schmitt trigger inputs with built-in pull-up resistor
(20k
Ω)
• Monitor output pin enabling real-time confirmation of
IC excitation
• The CLK and RETURN inputs provide an internal
noise elimination circuit as well as CMOS Schmitt cir-
cuit to prevent malfunction due to impulse noise.
• 4-phase distribution switch timing selected externally to
either CLK rising-edge only detection mode or both ris-
ing-edge and falling-edge detection mode
• ENABLE pin for excitation current cutoff, thereby
reducing system current drain when driver is stopped
