STK672-220-E

Ordering number : EN7465A STK672-220-E Thick-Film Hybrid IC Unipolar Constant-Current Chopper Two-Phase Stepping Motor Driver Output Current 2.8A http://onsemi.com Overview The STK672-220-E is two-phase stepping motor driver hybrid IC (HIC) that features further miniaturization and improved input logic flexibility as compared to the STK6713 series products. Applications The STK672-220-E 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. Inhibit pin (cuts off the motor current) Wide motor operating range (10 to 45V) Semiconductor Components Industries, LLC, 2013 June, 2013 71608HKIM/61504TN (OT) No.7465-1/10 STK672-220-E Specifications Absolute Maximum Ratings at Tc = 25°C Parameter Maximum supply voltage 1 Maximum supply voltage 2 Input voltage Output current Allowable power dissipation Operating substrate temperature Junction temperature Storage temperature Symbol VCC1 max VCC2 max VIN max IOH max Pd max Tc max Tj max Tstg Conditions No signal No signal Logic input pins 0.5s, 1 pulse, when VCC1 is applied With an arbitrarily large heat sink.
