因为这个隔离的存在,输入端和输出端之间就没有任何的电流,这个也就是我们通常所说的电气隔离 (Galvanic isolation)的意思。那么使用这类元器件的时候,我们就必须对电路板上的接地面进行分隔。 在实际的设计中,如下图所示的,在电路板上使用两个完全隔离的地平面,左边这个地是一个未隔离地,它用于电源模组的输入端,...
在该文件中,在第7页中给出demo板的原理图;如下所示 在改图中,GND1与输入端之间没有短接,与datasheet上的图存在不一致的地方。 个人疑问如下: Demo板的原理图中如果没有短接输入端和GND1,是不是输入相对于GND1是浮地的?如果这样如何保证其共模电压不会超过VDD1。 你好, 在datasheet的举例中,以马达为例子,...
PGND 和 GND 没有电气隔离。 我们建议将 PGND 和 GND 连接在一起,以便步进驱动器正常运行。 nSLEEP 不能由 DVDD 供电。您可以参考此帖,这是另外一个型号DRV8462类似的问题: https://e2e.ti.com/support/motor-drivers-group/motor-drivers/f/motor-drivers-forum/1328365/drv8462-drv8462-isolation , MEI Ji...
https://e2e.ti.com/support/isolation-group/isolation/f/isolation-forum/1184008/iso1042-isolation-in-gnd2-pin 器件型号:ISO1042 您好! 我们在设计中使用"ISO1042DWR" CAN 隔离收发器。 我们对与另一个电路板的隔离式接地连接有疑问。 我们的设计具有 用于 CAN 收发器的内部隔离式电源。 是否需要将隔...
Is it acceptable to connect this Pin 6(NC) of ISO7730 to GND directly? Regards, Oba Hi Oba, Thanks for reaching out. Yes, customer can directly connect Pin 6 (NC) to GND without any issue. The NC pin is internally not connected to any circuit and hence, we do not expect any issue...
I saw isolation was set to zero. And heard the suggestion to set it minimum to 12mil ? Is that correct? What about the width of the connections?Regarding GND pour, some tutorials (e.g. Funspark ...) say, it was very reasonable to use it, but didn't mention t...
