Part Number: ISO1541 Tool/software: Hi
TPA626 and ISO1541DR in the loop When the system is not powered on, the voltage of the power supply pin is about 1.6V to 2V. The IIC communication failure of TPA626 may cause the system to fail to start normally…
Hello,
Thanks for your reply.
The issue you have described now seems to be a logic voltage level compatibility related issue. The controller on the left side and the ISO1541 device may have a certain logic voltage level that does not allow for easy communication…
Part Number: ISO1541 Tool/software: Is ISO1541DR able to function as digital isolator for general open drain input signals and also be open-drain at the output? Essentially both sides will have pull up resistors.
Part Number: ISO1541 Tool/software: We are using an ISO1541 to communicate with a current sensor that is referenced to the AC line, but experience communication errors. Is there an issue when the isolated side is referenced to an AC line (in this case…

. Side1: VCC1-3.3V , GND1 -GND
. Side2: VCC2-5V , GND2 -PGND
check with the schematic diagram, we are not able to communicate two devices via ISO1541
Part Number: ISO1541 Hello expert,
My customer would like to know IBIS model behavior of ISO1541.
They used below IBIS model to simulate I2C signal , but they cannot see 0.65V~0.8V on side 1. Based on datasheet, there should be 0.65V~0.8V on side 1. Is…
Part Number: ISO1541 Can VCC1 be +3.3V and GND1 be 0V, along with VCC2 being -2V and GND2 be -7V?
I want to do this so I can interface a microcontroller running at VCC = 3v, GND =0v to the VCC1 side, to an LTC2945 power monitor measuring a negative supply…
Part Number: ISO1541 Hello Sir:
Please refer our waveform as below.
Ch1 is SCL1, Ch2 is SCL2
Ch1 is SDA1, Ch2 is SDA2
And below is our application circuit.
Would you please let us know why the SCL2 can not rise up at the last of waveform?
That effect…
Part Number: TCA9803 Other Parts Discussed in Thread: ISO1541 , TCA9800 , TCA9509 Hi team:
My customer use TCA9803 cooperates with ISO1541,
There is a problem in the debugging, which is shown in the following diagram, which is mainly realized as the SDA signal…
Part Number: ISO1541 I have a question about the ISO1541, could the silicon dioxide (SiO2) barrier be sensitive to moisture? Could that push its current drain higher? Have we tested this?
