Product Description
Overview of PT2465A:
The PT2465A is a stepper motor driver featuring H-bridge output current controlled by a PWM constant-current topology. Its built-in micro-stepping sequencer can generate sinusoidal output current for the stepper motor via a single clock input.
The PT2465A supports multiple excitation modes, including 2-phase, 1-2-phase, W1-2-phase, and 2W1-2-phase modes. The motor speed is determined by the clock frequency applied to the CK pin and the excitation mode, while the logic level of the CW/CCW pin dictates the forward or reverse direction of the bipolar stepper motor.
