Part Number: ISO1541 Other Parts Discussed in Thread: BQ34Z100-G1 , , BQ34Z100 , ISO1540 , TCA9517A , TCA9800 Hi
I am trying to isolate EVM2300 from custom board developed based on BQ34Z100-G1. I want to log charging and discharging as isolated.
I have used…
Part Number: ISO1541 Hello,
I would like to use the ISO1541 I2C Isolators, Side 1 connect to microcontroller and Side 2 will connect to external wire .
my product should get the following smartification IEC61000-4-2 ESD (4kV contact discharge , 8 kV air…
Part Number: ISO7762 Other Parts Discussed in Thread: ISO1541 , ISO7731 , TPS23881 , TPS23882 , This design guide ( http://www.ti.com/tool/TIDA-050026-23881 ) recommends ISO1541DR for I2C and ISO7731DWR for Reset, INT and OSS. Can I use ISO7762DWR which has…
Hi Shaquille,
Sorry about the delayed response. Thanks for sharing the waveform. Could you please confirm that this waveform is related to the same application/customer that I was talking about with Marx?
The bump in voltage from 0V to ~0.8V which you…
Part Number: ISO1541 Other Parts Discussed in Thread: ISO1540 Hi Team,
could you please provide me with the FIT / MTBF for the ISO1541D?
Thanks and Regards,
Mihir
Part Number: ISO1541 Other Parts Discussed in Thread: SN74LVC1G04 , ISO7041 , , SN6505B , SN6501 , SN6505A Hello, I see from the datasheet that this part uses max 4mA at 3.3V. So can this be powered from an LVC series logic gate, like a little inverter like…
Hi Anthony,
Thank you very much for sharing additional schematic of your application. I think I found the cause of the issue here.
From the schematic, I understand that Side2 of ISO1541 is connected to the MCP device while Side1 of ISO1541 is connected…
Part Number: ISO1541 Other Parts Discussed in Thread: ISO1540 My customer found the waveform with ISO1541 is not correct as below. However, when SCL2 is disconnected to uC, the waveform can become normal. it looks there is load effect with the signal…
Hello Darshan,
Thanks for reaching out. The VOL of ISO1640 is 570-710mV. All bidirectional and I2C isolators will have a side one offset like this to prevent latch-up conditions. See (+) [FAQ] Why is the logic LOW level output voltage, VOL1, up to 0.8V…
Hi Abhishek,
Apologies for the delay in getting back to you and thank you for sharing additional information.
I have also requested for MCU part number and its I2C I/O threshold information to one of my colleagues who I believe is working with you. Once…
