Other Parts Discussed in Thread: ISOW7841A-Q1 , ISOW7841 , ISOW7741 Dear expert
I'm developing new product with ISOW7841q.
I want know the frequency.
First, the switching frequency on DC-DC converter part. (Transformer Drive)
Second, Carrier signal through…
Part Number: ISOW7841A-Q1 Other Parts Discussed in Thread: ISOW7841 , ISO7741-Q1 , , ISO7741 Hi experts,
Could you please let me know what is the means of suffix 'A'? Functional safety? If yes, does it means any difference in electrical performance or features…
Part Number: ISOW7841A-Q1 The datasheet no longer recommends to have an input capacitor 100uF larger than the output capacitor. Does that mean that the ISOW7841A-Q1 device can no longer loose Viso regulation in some cases if the Vcc capacitance is too…
Part Number: ISOW7841A-Q1 Other Parts Discussed in Thread: ISO7841 Hello,
1 : Need to calculate the power dissipation of Isolation buffer. We require the output isolation side current consumption at 10mbps speed. Please provide the data, it is not present…
Part Number: ISOW7841A-Q1 Hi team,
I have a part from yourselves that I cannot confirm the top marking of XISOW7841FAQDWERQ1 the datasheet nor the top marking check on your website give any information for this device, the part marking on the received…
Part Number: ISOW7841A-Q1 Other Parts Discussed in Thread: ISOW7841 Dear experts.
I used the ISOW7841 for our application. I only use one input and one output.
I don't use the other two pins. Which is the better for EMC performance?
the not used pins…
Part Number: ISOW7821 Other Parts Discussed in Thread: ISOW7841A-Q1 Hello,
I can see that the datasheet clearly shows 3 use cases for VCC to VISO which are
5V to 5V
5V to 3.3V
3.3V to 3.3V
Will 3.3V to 5V not work at all? Could it work for a much lower…
Hi Daria,
Thanks for reaching out and sorry to hear about the issue.
Thanks also for sharing detailed information related to the issue that customer is facing. Just for experimenting, could you please order ISOW7841A-Q1 samples for customer and ask them…
Hi Ray,
Thanks for reaching out.
3.3V to 5V conversion is a boost-mode operation where the input current requirement is going to be significantly higher than the output current drawn. Due to this, the device is not going to output similar currents as…
Hi Jens, Our ISOW7841A-Q1 device has the ability to "boost" a 3.3V Vcc input to 5V on Viso output. Please allow me to follow up with you via email regarding "boost" mode for ISOW7840. Thank you, Manuel Chavez
