STK672-210

Ordering number : ENN7464 SANYO Semiconductors DATA SHEET Unipolar Constant-Current Chopper STK672-210 Overview Two-Phase Stepping Motor Driver Output Current: 1.4 A 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.
