Transmission signal from applied input TLE6251DS. driver switches CANH/L output stages transfer this input signal lines. Time-out Feature signal dominant time tTxD time-out function deactivates transmission signal bus. This realized prevent from being blocked permanently dominant error. transmission released again, after rising edge been detected. Reduced Electromagnetic Emission driver implemented control reduce electromagnetic emission (EME). This achieved controlling symmetry slope, resp. CANH CANL. Overtemperature driver stages protected against overtemperature. Exceeding shutdown temperature results deactivation driving stages CANH/L. avoid failure after cooling down, signals transmitted again only after dominant recessive edge TxD. Figure shows transmission stage deactivated activated again. First over temperature condition causes transmission stage deactivate. After over temperature condition longer present, transmission only possible after signal changed recessive level.
