Tomas,
The ISO7241A does have an EN pin that can be driven LOW to force the output to high impedance, but there is no input channel switch for the same. Can you share an image of the noise pulses caused by SPICLK switching? It would be good to see both…
Hi Jakub,
first, I want to make sure that I am looking at the same board that you have. Can you confirm that you are working with the DRV8301-69M-KIT ?
I am looking at the circuit around U5, the ISO7241 which is between the device and J8. The configuration…
Other Parts Discussed in Thread: MOTORWARE , DRV8301 , CONTROLSUITE Dear My Friends:
I have a PMSM , resolver kit and Hv-kit with F28069 controller and I hope to use SPI(slave) to get PMSM postion from resolver Kit(master).I found that there is a SPI-A interface…
Other Parts Discussed in Thread: ISO7231C I'm just learning the characteristics of the ISO series components and I ran across this anomaly with the ISO7241A; ref page 13 SLLSE18 –JANUARY 2010. So my question is this : Does this technology (galvonic isolation…
Ok finaly i got a solution for the problem. The TMS320F28069M and the AM3359 work with MOSI and MISO, but on the F28M35xx only the C28 work with MISO and MOSI. The M3 work with TX and RX. This is realy confusing, because all the other processors change…
You are correct, Calum, the '245 does not provide the classic definition of isolation. For digital isolation, you would have to use one of the ISO7xxx devices, depending on the configuration required. For example, for a 2TX/2RX configuration, the…
Hi Tomek,
The easiest way to do this would be to use a device like the ISO7241A. That is a 4-channel isolator that provides three channels in one direction and the fourth the other way across the isolation boundary - this make it easy to implement an…
