 Hello and welcome. This video will demonstrate the efficiency of STESD protection devices for communication lines. Our solution fits many applications, whether they are for industrial, IoT or automotive. As an example, this demo will focus on CAN and LIN communication systems. This demonstration is based on two identical evaluation boards, which lets you easily evaluate our ESD protection diodes and transient voltage suppressors. The demo embeds two wide-voltage spark generators so that real electrostatic discharges can easily be created. A rocket switch lets you choose either the CAN communication protocol on the left-hand side or the LIN communication protocol on the right-hand side. There are two black spark housings through which the communication wires pass. A push-button is used to manually trigger sparks in the black housing, simulating ESD. You can see those sparks there. The evaluation board is based on a master-slap structure on the same board using two automotive microcontrollers. The microcontrollers communicate with each other via a communication loop based on the LIN or CAN protocol. The communication status is indicated by four on-board LEDs. The LIN and CAN bus interfaces use four transceivers powered by the 12-volt supply issued by the step-up converter. The ESD protection TVS highlighted in the CAN setup part are D1, D2 and D7, D8 on the CAN communication link. The ESD protection TVS highlighted in the LIN setup part are D17, D18 and D14, D15 on the LIN communication link. Let's start with CAN communication. After switching on the power, let's initiate the demo sequence. The three color LEDs start blinking sequentially to indicate normal communication. Pushing the button generates a spark on CAN wires. The system continues to communicate. Software defects can occur. However, the system restarts by itself showing that no hardware has been damaged. Now, let's switch to the LIN board. Sparks are generating on LIN wire. No hardware failures can be observed on LIN setup with our ESD protection. As for CAN, software faults can occur as well. However, system restarts by itself showing that no hardware has been damaged. In this video, we demonstrated that even in the case of repetitive ESD surges, the application keeps on working without damage thanks to ESD's efficient protection devices. While CAN and LIN communication protocols were used in this demo, our solutions are valid for all other communication purposes. ESD recommends using ESD protection ICs to ensure the reliability and robustness of higher low-speed microcontroller interfaces in industrial IoT and automotive applications.
