車載用 40V耐壓 低功耗雙極PWM恆流驅動 步進電機驅動器
BD63800MUF-C是一款電源額定電壓40V、額定輸出電流1.35A的低功耗雙極PWM恆流驅動的驅動器。輸入接口採用CLK-IN驅動方式和SPI-IN驅動方式。勵磁模式支持Full step、1/2 step、1/4 step、1/8 step、1/16 step、1/32 step模式。電流衰減方式備有可自由設置Fast decay / Slow decay 比例的Mix decay模式和可自動選擇Fast decay / Slow decay的Autodecay模式，可使各種電機實現理想的控制狀態。另外，電源也可以用1個系統進行驅動，使配套應用的設計更容易。
