Part Number: ISO1541
Tool/software:
Hi everyone,
I'm working with an MCU (3.3V) as an I2C master, and I need to isolate two different segments of the bus to interact with:
Two DACs (0x20 and 0x21, powered at 5V) for analog outputs (0–10V and…
Part Number: ISO1541 Tool/software: Hi,
Is it possible to use ISO1541 as isolator for I2C line under conditions of VCC1=3.3V, GND1=0V, VCC2=0V, GND2=-5V?
I have found the following URL and assume that it can be used under these conditions.
https…
Part Number: ISO1541 Other Parts Discussed in Thread: ISO1641 Hello,
My customer had developed products using the ISO1541DR.
They believe this is a legacy part released long ago.
Could you please recommend a new device that can replace the device…
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…
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…
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 Other Parts Discussed in Thread: TMP102 , TCA9406 Tool/software: Hi All,
I am working on a design that uses I2C to communicate to three devices:
1. TPL0102 (digital potentiometer) through an I2C isolator ISO1541
2. TMP102 (temp…

. 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…
Part Number: ISO1541 Other Parts Discussed in Thread: ISO1540 , ISO1640 , ISO1641 Hi Team,
Customer would like to design ISO1541 for I2C interface. Would you please help review questions and provide your comments?
1.customer power domain is as below…
