Part Number: TCA9802 Other Parts Discussed in Thread: ISO1641 , TCA9509 Tool/software: We have processor driving side A of TCA9802 (2.2k pullups).
Then side B of TCA9802 is connected to ISO1641 (side 1) - no other I2C device.
Side 2 of ISO1641 is connected…
Part Number: ISO1641 Tool/software: Hello,
We are using the ISO1641 in an I2C level translation application with Side 1 at 3.3 V and side 2 at 5V. We do not need the isolation feature, so the grounds on both sides of the device are tied to our common…
Part Number: ISO1641 Other Parts Discussed in Thread: ISO1640 , Tool/software: e2e,
I missed we couldn't support clock stretching with the ISO1641BDR and would appreciate some input on whether the ISO1641BDR is
somehow more robust for applications…
Part Number: ISO1641 Other Parts Discussed in Thread: TCA9800 , Hi team,
customer Master SOC VIL is 0.54V,
so they think our buffer output 0.65V (VoL1) is too high to be read correctly , is there any workaround we can do to lower down this 0.65V?
Part Number: ISO1641 Other Parts Discussed in Thread: TCA9511A , TCA4307 ,
Hello,
The system I have is a back-plane board where power modules can hot plug into. Below screen shot is triggered on the hot-plug event.
Blue trace is I2C bus side SDA, and yellow…
Part Number: ISO1641
Hello,
We have implemented an isolated I2C Bus using ISO1641BDR.
Communication works properly. No communication errors are occurring says our FW team.
Not sure why the image below is so hazy; But, the Yellow trace is micro-controller…
Part Number: ISO1641 Other Parts Discussed in Thread: ISO1640 Hi, we're trying the isolator ISO1641B to isolate I2C communication. Below is the schematic:
As the test circuit, both the master and slave devices are Arduino Uno operating at 5V.
We're…
Part Number: BQ76942 Other Parts Discussed in Thread: ISO1641 , , ISO1640 Hi all, this is a continuation of my previous post on the Isolation Forum: https://e2e.ti.com/support/isolation-group/isolation/f/isolation-forum/1340104/5105191
I've been trying …
Part Number: ISO1641 Hello Team,
My customer found a confusing specification in our datasheet.
We have the following specification:
I f I see this correctly, then the threshold where we recognize high and low could possibly overlap, namely exactly when…
Part Number: ISO1641 Other Parts Discussed in Thread: BQ76942 , BQ76952 , , ISO1640 Hi all,
I've been testing an ISO1641B IC to perform isolated I2C communication, between an MCU Master, and a BQ76942 AFE slave (address 0x60). Unfortunately I have been unable…
