... Reverse Polarity Protection There is a reverse polarity protection implemented in the TLE7237SL. This protection has to be divided into two parts. First the protection of the control circuits and second in the protection of the power transistors. The control circuits are reverse polarity protected by protective measures in the ground connection. In case of reverse polarity, there is no current flow through the control circuits ...
