STK672-210 ^{Two-Phase Stepping Motor Driver}
Output Current: 1.4 A
Overview
The STK672-210 is two-phase stepping motor driver hybrid IC (H-IC) that features further miniaturization and
improved input logic flexibility as compared to the STK6712 series products.
Applications
The STK672-210 is optimal for use as a stepping motor driver in printers, copiers, XY plotters, and similar equipment.
Features
• Built-in common-mode input protection circuit
• The input signal logic lines are provided as active-high and active-low pairs, and thus support switching the motor
wiring.
• Built-in current detection resistor for reduced external component mounting area on the printed circuit board.
• Wide motor operating range (10 to 45 V)
