To minimize spectral content the CANH output waveform is controlled Logic low TxD L on pin TxD will command the output stage to switch to dominant high potential TxD H to recessive low on the bus To avoid the bus to be blocked by a permanent dominant TxD input signal the TLE 6255 G incorporates a timeout feature In case of TxD L for longer than the internal fixed timeout the CANH output is switched off automatically The timeout is resetted by a H signal at TxD without a delay The loss of an ECU ground may cause the ECU to source current through the various ECU circuits to the communications bus instead of to the vehicle system ground Therefore the unit load resistor of any ECU is connected to the LOAD pin The TLE 6255 G incorporates a reverse protected switch from LOAD to ground potential This switch is automatically switched off in a loss of ground state 6 4 Receiver In normal high speed and wakeup mode all data on the bus is sensed by the receive comparator and transmitted to the RxD output In sleep mode no normal level data is detected The receiver threshold is set to the wake up level So a wake up interrupt is sent only in case of a wake up call on the bus An internal fixed filter improves the EMC susceptibility Data Sheet Rev 2 5 6 2003 11 27 C Infineon TLE 6255 G technologies 6 5 Unit Load Resistor The TLE 6255 covers the specification GMW 3089 V1 26 or the so called first generation of SW CAN GM decided
