Part Number: ISO7840 Tool/software: The following is stated in section 8.4 of the document SLLSEN2B.
A strongly driven input signal can weakly power the floating VCC through an internal protection diode and cause undetermined output.
What exactly is…
Part Number: ISO7840 Other Parts Discussed in Thread: UCC27714 , ISO7740 , ISO6740 , Tool/software: The OUT signal of the ISO7840F occasionally becomes unstable. When VCC1 = 3.3V, VCC2 = 5V, EN2 = 5V, and INA = 0V (Low), OUTA is output at a fixed 2.5V. When…
Part Number: ISO7840 Hello team,
ISO7840 datasheet says the part is VDE V 0884-10:2006-12 certification completed.
Now it has been updated to V 0884-11:2017-01. Can I think ISO7840 is now certified V 0884-11:2017-01?
Best regards,
Part Number: ISO7840 Hello,
The failure of the ISO7840 device occurred in my customer's system that was installed in the field.
Damage is observed on the top of the package as shown below.
Could you please tell us the conditions such as surge level…
Part Number: ISO7840 Other Parts Discussed in Thread: ISOW7840 , Hello,
Understanding failure modes in isolators (jajy037) states that EOS damage is limited to high-powered dies.
When using with GND1 and GND2 connected, is the other VCCpin or OUTpin affected…
Part Number: ISO7840 Other Parts Discussed in Thread: ISO7740 , Hi team,
Can you explain the difference between ISO7740 and ISO7840? Why is ISO7840 more robust? Does it have a thicker SO2 layer?
Thank you,
Franz
Part Number: ISO7840 Hello,
What would be the correct approach to override the default state of OUTx pins in case of loss of Vcc1 and/or Vcc2?
Assuming the device is an ISO7840 would it be ok to add a weak pull down on the output of the desired OUTx pin…
Part Number: ISO7842 Other Parts Discussed in Thread: ISO7840 Tool/software: Hello,
according to the datasheet, the maximum allowed value of the output current of ISO7842 is 15 mA. Is it allowed to connect an RC circuit consisting of serially connected…
