BD63725BEFV
高性能、高可靠性36V耐壓 步進馬達驅動器
BD63725BEFV是額定電源36V、額定輸出電流2.5A的低功耗雙極PWM恒流驅動器。輸入介面採用CLK-IN驅動方式,透過內建DAC,勵磁模式可適用於FULL STEP、HALF STEP(2種)、QUATER STEP模式。電流衰減方式方面可任意設定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,有助於提高應用設計的便利性。

Reference Design / Application Evaluation Kit
-
- Evaluation Board - BD63725BEFV-EVK-001
This evaluation board is a board for driving the stepping motor with a ROHM's stepping motor driver BD63725BEFV. Motor drive and driver The motor can be driven by VCC for power supply and 5V power supply for control signal. Drive / stop and excitation modes can be set with an external switch. The input interface adopts the CLK-IN drive system, and the excitation mode supports FULL STEP, HALF STEP, QUATER STEP, 1/8 STEP, and 1/16 STEP mode by the built-in DAC.
