1 / 11 page STK672-050 SANYO Electric Co., Ltd. Semiconductor Business Headquarters TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110 JAPAN N2997HA(ID) / 11896HA(ID) No. 5228—1/11 Ordering number: EN 5228A 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 Package Dimensions unit: mm 4164 Series Organization The following devices form a series with differing output capacity.
