TC78S600FNG Overview
TC78S600FNG/FTG CD Integrated Circuit Silicon Monolithic TC78S600FNG/FTG Stepping Motor Driver IC The TC78S600FNG/FTG is a PWM constant-current type stepping motor driver IC designed for sinusoidal-input micro-step control of stepping motors. The TC78S600FNG/FTG is capable of forward and reverse driving of a 2-phase bipolar stepping motor using only a clock signal.
