STEVAL-OET003V1
Evaluation board for automotive-grade 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 automotive
environment. It is based on a master-slave
structure on the same board using two
STM8AF528.
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 5 V
12 V output, step-up converter for
transceiver supply voltage
LIN transceiver
CAN transceiver
Automotive-grade ESD protection
IEC61000-4-2 compatibility
