µ-step適用 36V耐壓 步進馬達驅動器系列 - BD63525AEFV

BD63525AEFV是適用於1/16µ-step的步進馬達驅動器。作為基本功能,是低功耗雙極PWM恒流驅動器,額定電源為36V、額定輸出電流(DC)為2.5A,介面為CLK-IN驅動型。透過內建DAC,勵磁模式適用於Full step (2相勵磁)、Half step (1-2相勵磁)、Quarter step (W1-2 相勵磁)、Sixteenth step (4W1-2相勵磁)模式,對於電流衰減方式,可自由設定FAST DECAY/SLOW DECAY的比率,可對所有馬達實現最佳控制狀態。另外,也可使用一個系統電源進行驅動,因此有助於提高應用設計的便利性。
