Hello Akarsh,
Yes, the INA260 will work with AC common-mode voltages as long as you operate it on floating supplies. Once again, the TI design document www.ti.com/.../tidudp5.pdf shows how the ISOW7842 can be used to conveniently float the INA260 and…
Hello Nabeen,
If I understand correctly, your desired current sensing implementation is like the figure below. I think the INA260 paired with ISOW7842 will help you achieve what you want. The configuration is detailed in the following application notes…
Part Number: ISOW7842 Other Parts Discussed in Thread: SN6501 , ISO7742 ,
Hi,
My customer is selecting ISO device and worried about "ISOW7842" or "ISO7742+SN6501".
They mind not size but efficiency and EMI(and cost).
I'm understanding that efficiency…
Hi Andrey, Thank you for including PCB images and a schematic. What is the expected load on Viso pins? Is the same unit (DD1, DD12, DD3) failing in each system? What is the voltage level during short conditions?
This may not be the cause of failure…
Hi Mitch,
As Clemens has mentioned, please refer to Designing an isolated I²C Bus ® interface by using digital isolators . According to Figure 5, two digital channels in opposite directions are required to realize one I2C channel.
ISOW7842 (2 forward…
Other Parts Discussed in Thread: TRS3122E , ISOW7842 , TRS202E Hi everyone,
I have an application that need to design an isolated board to transfer RS232 signal 12V to TTL 12V with the rate 115k. I thought the TIDA-0123 ( www.ti.com/.../TIDA-01230)…
Hi Barry,
Thank you for trying to implement the isolation for the UART2_DE pin as well. ISOW784x is available with various input/output channel configuration. Usually the primary of ISOW gets connected to MCU and secondary to RS-485 transceiver, for…
DEEPAK,
The data sheet says the power supply and common mode voltages need to be above 2.7 V, so your circuit should work with 3.3 V.
There is another TI design that goes into some detail on measuring voltage with a current shunt monitor on the negative…
Hi Adi,
Yes, it is possible to extend this to achieve 3-phase voltage and current measurement. There are multiple ways of implementing three phase measurement using shunt and voltage divider.
1. If you are using low side voltage measurement, you can…
