Summary
1 Summary
This document is guideline for the LIN LDO transceiver demoboard in DSO-8 / TSON-8 package from Infineon
Technologies AG and provides information for the proper usage of the demoboard.
The demoboard can be used for all standard LIN LDO transceiver on the market, which fulfill the OEM required
standard pinout for DSO-8 / TSON-8 package (see Figure 1).
Figure 1 Pin-out of Infineon 8-pin LIN LDO transceiver TLE8457x
2 General Function
The demoboard can be used for various test cases and various LIN LDO transceiver. Power supply failures can
be simulated as well as different modes of operation. The demoboard should be used to evaluate existing and
new LIN LDO transceivers on the market. Advantages, risks and disadvantages of competitor devicese versus
Infineon devices can be tested an measured.
