Hi Manjunath, Thank you for posting to E2E! The SN6505A circuit of the schematic looks great; we will just recommend R65 be replaced with a 4.7kΩ resistor if possible and that in the PCB layout, C88 be placed within 2mm of the transformer's primary-side…
Hi Cyan,
Wanted to add on to what Abhi has said here. As he mentioned, a block diagram would be helpful.
It looks like you are able to induce damage to side 2 of the ISO1050DUB. You are correct, that the absolute max for the CANH and CANL pins is…
ISO1050DWR can withstand 1.2/50us surge pulse of 4000 Vpk.
We recommend to consider newly-released ISO1042 CAN transceiver which can withstand surge pulse of 10000 Vpk.
Hi Red, Thank you for posting to E2E! In CAN communication, the standard cable used has a characteristic impedance of 120Ω. Waveforms of CANH-CANS and CANL-CANS may be helpful for understanding where the noise originates although communication occurs…
Hi Morris,
Since the battery packs use the isolated CAN device ISO1050, they can be connected to each other and to the external CAN bus without any issues. The isolated CAN itself will work like a voltage level translator and hence you do not need any…
Hi Chen,
Digital isolators are designed to support logic signaling (e.g., TTL or CMOS) and generally cannot support the CAN physical layer directly (which is unique in using bidirectional differential dominant/recessive signaling). So, the second picture…
Hi Needhu,
Thanks for asking your questions on E2E!
The ISO1050 uses an edge based architecture to transmit digital data. Further details on that can be found in the Digital Isolator Design Guide . (See section 1.1 and 1.2 on pages 2 and 3 for edge…
Part Number: TXS0102 Other Parts Discussed in Thread: ISO1050 , TXS0104E , SN74AXC2T245 , ISO1044 , ISO1042 Hello,
I want to use TXS0102 for level shifting from 1.8V (my CAN controller works at 1.8V) to 3.3V (TI ISO1050 CAN transceiver accepts at 3…
Jouko,
See the first section of this presentation for a clear understanding of our isolation architecture. In short, our digital isolators achieve isolation through 1 or 2 capacitor stages with a SiO2 dielectric for basic or reinforced isolation respectively…
Hi Wayne,
Your customer is experiencing this communication delay issue because Vcc2 is not discharging down to 0V before the supply is brought back up.
The ISO1050 needs to have the supply brought below 0.3V (and ideally as close to 0V as possible…
