1 EVAL-OET00V Evaluation board for - ESD protection Data brief Description This demonstration tool is designed to provide an easy way to evaluate the robustness of ESD diodes developed for the environment. It is based on a master-slave structure on the same board using two MAF. The microcontrollers communicate with each other via a communication loop based on LIN/CAN protocol. Communication flow status is indicated by four onboard LEDs. The LIN and CAN bus interfaces use four transceivers and are supplied by the step-up converter. Features Input voltage V V output, step-up converter for transceiver supply voltage LIN transceiver CAN transceiver Automotive- ESD protection IEC000-- compatibility August 0 DocID090 Rev /0 For further information contact your local Microelectronics sales office
