PT2465A Overview
The PT2465A is a stepping motor driver, the Hbridges output current controlled by PWM constantcurrent topology. Built-in micro-step sequencer could generate sinusoidal output current to the stepping motor by a single clock input. The motor rotation revs determinate by the clock frequency applies on CK pin and excitation mode, the CW/CCW pin logic level determinate bipolar stepping motor in forward or reverse...
