AN44180A - 37V / 1.5A Stepping Motor Driver

Features

  • 4-phase input control Built-in standby function → 2-phase, half step, 1-2 phase, W1-2 phase excitation enabled → The operation of standby function can lower current PWM can be driven by built-in CR (3-value can be selected during consumption of this LSI. PWM OFF period. ) Built-in 3.3 V power supply (accuracy : ±3%) → The selection of PWM OFF period enables the best PWM drive. Built-in EMI reduction function Mix Decay control (4-value can be selected for Fast Decay ratio) Built-in malfunc.

AN44180A 37V / 1.5A Stepping Motor Driver FEATURES 4-phase input control Built-in standby function → 2-phase, half step, 1-2 phase, W1-2 phase excitation enabled → The operation of standby function can lower current PWM can be driven by built-in CR (3-value can be selected during consumption of this LSI. PWM OFF period.) Built-in 3.3 V power supply (accuracy : ±3%) → The selection of PWM OFF period enables the best PWM drive. Built-in EMI reduction function Mix Decay control (4-value can be selected for Fast Decay ratio) Built-in malfunction prevention function when it don’t input → 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.
