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.
