TH8062 General Description
The TH8062 consists of a low-drop voltage regulator 5V/70mA and a LIN bus transceiver. The LIN transceiver is suitable for LIN bus systems conform to LIN specification revision 2.0 and SAE J2602.
The combination of voltage regulator and bus transceiver makes it possible to develop simple, but powerful and cheap slave nodes in LIN Bus systems.

TH8062 Frequently asked Questions
About TH3122
Answer
In principle is the physical Layer of K-Bus and LIN comparable from the voltage leveles as well as from the timing. The base for the LIN definition was the K-Bus. The only difference you have to take into acount is the termination: With K-Bus you have always external pull ups in summary over the whole network of max 500Ohm and no reverse diode. With LIN you have always the slave termination integrated 30k/diode and at the LIN master a 1k with diode termination must be added external on this module. Back to your question: If you want to change from K-Bus to LIN you can use the TH8082 as pure physical layer transceiver or you can also use our TH8062 which is a physical layer LIN transceiver plus a voltage regulator 5V/70mA similat to the TH3122. To switch from K-Bus to LIN you have to secure that all external termination resistors from old K-Bus will be deleted and only at the LIN master module the 1k termination must be added. The LIN protokoll is a complete other story, means this is complete differnt to K-Bus. You need on the protocoll side a new software driver for your MCU.
Answer
yes, you can use the TH8080 as physical layer. The TH3122 has additional integrated a voltage regulator. In case you use the TH8080 you must add this voltage regulator if you need it on you module as separate part or you use our new TH8062 which has already a 70mA voltage regulator and a LIN physical layer integrated. The pure physical layer of K-Bus and LIN is comparable. The protocol is different! The termination network for K-bus is always external and for LIN you have it for all slaves already integrated. I don't understand you last paragraf! Therefore I have forward you email to our technical rep located in Hong Kong. Perhaps it is better to discuss with him directly. He will contact you asap.
Question
I am thank your reply very much. Excuse me, My english is not good. Above my last paragraph is next note. Now we are develop a body control module with K bus. I want to use TH8080 or TH8062 for k bus tranceiver of my body control module. I want to know that TH8080 or TH8062 can is or not use for k bus tranceiver? If my BCM with k bus use TH8080 and other ECU with k BUS use TH3122, then communication can is or not normally run between them which is connect a k bus?
Answer
want to use TH8080 or TH8062 for k bus tranceiver of my body control module. I want to know that TH8080 or TH8062 can is or not use for k bus tranceiver? This is possible. We have one customer which has such a solution is series production! If my BCM with k bus use TH8080 and other ECU with k BUS use TH3122, then communication can is or not normally run between them which is connect a k bus? If you use the K-Bus protocoll for communication then it should be possible. Up to now we don't have such a case, but from the principle this should work. All of our LIN transceiver are also compatible to K-Bus.
