Hi,
大家好！有个问题想请教大家一下，谢谢。
如下一个马达控制电路的电源部分，添加了一个LPC电路，为什么要加？有一些英文资料，不是很懂，望大家指点。
Low Pass Filter the spindle Rsns signal and send that to the SPNRTN pin. LPF of 10 to 20 kHz.
Instead of tri-stating when Rsns current exceeds a limit, tri-state when the apparent spindle current coming from the 5V supply reaches a limit. Since the current being drawn from the 5V supply is filtered by isofet resistance, trace resistance, supply resistance, and various capacitors, the Rsns signal must be similarly filtered.
