PT2465 Datasheet | Princeton Technology

DESCRIPTION The PT2465 is a PWM constant-current type stepping motor driver designed for sinusoidal-input micro-step control of stepping motors. The PT2465 provides several excitation modes for bipolar stepping motor, such as 2-phase, 1-2-phase, W1-2-phase and 2W1-2 phase. The PT2465 is capable of forward and reverse driving of a 2phase bipolar stepping motor using only a clock signal.
