Part Number: ISO1640 Other Parts Discussed in Thread: ISO1540 , Does ISO1640 has lower Vol for Side 1 compared to ISO1540 which has Vol range of 570mV to 800mV?
I am looking for i2c isolator which has lower Vol. We are hitting Vil violation due to high…
Part Number: ISO1540 Hi Ti experts,
We are using ISO I2C ISO1540 to connect MCU and many devices as below:
We found that when ISO1540 receives signals from MCU, there will be a platform at the rise edge as below, which will cause the communication r…
Hi Allen,
Allen Du said: the A side of TCA9509 VIL Max is 0.3V, but the FPGA on my board VoL max is 0.45V, there will be a problem.
The A side of TCA9509 is actually lower at 150mV typical. Most people don't have an issue with this if they design the bus…
Part Number: ISO1540 Other Parts Discussed in Thread: BQ76942 Hi Team,
Currently, customer used our ISO1540 meet some corner issue:
In customer system, he add a switvh(MOS) in the line of VCC, to turn-on and turn-off ISO1540, but at the time, SDA/SCL…
Part Number: ISO1540 Hello expert,
May we know the difference between Icc and IOL? My customer would like to do the power simulation and need to know IC consumption for ISO1540. For my opinion, they should take Icc as consideration since Icc is IC consume…
Part Number: ISO1540 Other Parts Discussed in Thread: ISO1452 , ISO1450 Hello team,
Is it possible to use those ISO154x bidirectional I2C isolators for isolating other communication protocols which are not I2C ?
Specifically I thought to use it for isolating…
Part Number: ISO1540 I am using a ISO1540 to read the SMBus of some BB2590 batteries. The relevant part of the circuit is shown in the images below
The issue that I am having is that sometimes when connecting or disconnecting the batteries, U14 gets damaged…
Part Number: ISO1540 Other Parts Discussed in Thread: ISO1640 Hi,
We consider to use the ISO1540 for the GPIO isolation, so please kindly advise if this is available, thanks.
Part Number: ISO1540 Hi!, I'm up to connect a LIN interface which is lifted up 12 V. I saw the thread https://e2e.ti.com/support/isolation-group/isolation/f/isolation-forum/738426/iso1540-isolating-lin-bus-nodes-at-12v-violates-absolute-maximum-ra…
