Part Number: TIDA-01238 Tool/software: Hello, Is it possible to add a Common-Mode filter capacitor in combination of selectable resistors? For example, as in the following circuit.
However, to protect against a short to the battery in automotive applications…
Part Number: TIDA-01238 Tool/software: Hello,
To engage the termination resistor on FET solution, only U4 should be turned on by driving its gate to 5 V. Therefore, JMP9 should be connected to VCC and JMP10 to GND (to keep U3 turn off), correct? The…
Part Number: TIDA-01238 Tool/software: Hi, Team
Hope you are doing well!
My customer has read this reference design and is interested in the solution.
Customer wants to learn about if this solution has been used in any mass production projects?…
Part Number: TIDA-01238 Hello,
I am implementing a circuit based on this. For most of our products we have to survive short to 16V and short to GND.

Part Number: TIDA-01238 Hi!
I'd like to make TIDA-01238 . I downloaded gerber and other files but I couldn't find the NC drill file which is needed to make PCB.
Can you give it to me please?
Thanks, George
Hi Kazuya-san,
The below reference design goes over two methods of using selectable termination in CAN designs. The concept and execution will be identical in an RS-485 implementation. Let me know if this is what is needed for the current design consideration…
Other Parts Discussed in Thread: TIDA-01238 Hello, everybody, i want to make the termination resistor selectable for a can transceiver. I have seen the referencedesing for an isolated input. There, a photo transistor from Toshiba is used to select the…
Howard,
This TIDA covers a method of selecting which nodes are terminated. I believe this could be adapted to be compliant with isolation.
Another way is to simply have a mechanical switch that switch that controls whether or not the node is…
Hi Stanley, Using three 120-ohm resistors in parallel may not be problematic in some cases, but the CAN devices may have trouble driving a dominant signal since the resistors will be sinking greater amounts of current. If three resistors must be used…
Part Number: THVD1449V Other Parts Discussed in Thread: THVD1454 , THVD1424 , TVS1401 Hi
We've got an upcoming RS485 Design. Our requirements for this interface are:
500Kbps RS485
Half Duplex
IEC61000-4-5 Level 2 (8/20us test: 1KV / 42 ohms…
