AN44183A - 37V / 4.0A Microstepping Motor Driver

Key Features

  • Built-in decoder for micro steps (2-phase, half step, 1-2 phase, W1-2 phase ,2W1-2 phase, and 4W1-2 phase excitation ) → Stepping motor can be driven by only external clock signal Interface: Clock (Rising edge detection and both edge detection) PWM can be driven by built-in CR (2-value can be selected during PWM OFF period. ) →The selection of PWM OFF period enables the best PWM drive. Mix Decay control (4-value can be selected for Fast Decay ratio) → Mix Decay control can improve accuracy of mo.

AN44183A 37V / 4.0A Microstepping Motor Driver FEATURES Built-in decoder for micro steps (2-phase, half step, 1-2 phase, W1-2 phase ,2W1-2 phase, and 4W1-2 phase excitation ) → Stepping motor can be driven by only external clock signal Interface: Clock (Rising edge detection and both edge detection) PWM can be driven by built-in CR (2-value can be selected during PWM OFF period.) →The selection of PWM OFF period enables the best PWM drive. Mix Decay control (4-value can be selected for Fast Decay ratio) → Mix Decay control can improve accuracy of motor current waveform. Built-in over-current protection (OCP) → If the current flows to motor output more than the setup value due to ground-fault etc., the OCP operates and all motor outputs are turned OFF.
