Application Information successor first generation CAN, 6251 designed provide excellent passive behavior when transceiver switched (mixed networks, terminal 15/30 applications). current consumption reduced, power modes. This supports networks with partially powered down nodes. wake-up from power modes possible message bi-level sensitive wake input external voltage supply controlled inhibit output INH. powered down 6251 still reacts wake-up activities local wake input activities. diagnosis output NERR, allows mode dependent enhanced diagnosis failures wake-up source. VBAT fail flag reports power-on condition battery supply input. VBAT fail flag will resetted after first transition into normal mode. 6251 four operation modes, normal, receive only, standby mode sleep mode. These modes controlled with control pins NSTB (see Figure Table Both, NSTB, have implemented pull-down, there signal applied NSTB, transceiver automatically changes standby mode. Normal Mode transfer 6251 into normal mode, NSTB have switched HIGH level. This mode designed normal data transmission/reception within HS-CAN network. Transmission signal from applied input 6251 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 error. transmission released again, after mode state change. Short Circuit Feature Similar time-out, short circuit would also drive permanent dominant signal block communication. avoid this, 6251 short circuit detection.

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 overtemperature condition causes transmission stage deactivate. After overtemperature condition longer present, transmission only possible after signal changed recessive level.

Permanent Recessive Clamping signal permanent recessive, although there message sent bus, host this transceiver could start message time, because seems idle. prevent this node disturb communication bus, 6251 offers called permanent recessive clamping. signal permanent recessive, error flag transmitter deactivated long error occurs Receive Only Mode (RxOnly Mode) RxOnly mode, transmission stage deactivated reception signals still possible. This mode implemented support hardware software diagnosis functions. there hardware error transmission part node (e.g. bubbling idiot failure), RxOnly mode, longer blocked still receive messages bus. also possible make network analysis interconnections between nodes. connection between nodes network) checked both nodes normal mode others RxOnly mode. message from node sent other, this acknowledged. there acknowledge message, connection between nodes error. also works diagnosis flag, which described more detail Table

Once wake-up flag LOW), remains this state, long transceiver transferred into normal mode. detection wake-up source possible during first recessive dominant edges normal mode. Go-to Sleep Mode go-to sleep mode used have intermediate step between sleep mode other modes. This mode control sleep command NSTB activated minimum hold time thSLP. Afterwards 6251 automatically transfers into sleep mode. activated features go-to sleep mode similar standby mode. Sleep Mode sleep mode, transmission reception signals deactivated. This second step reducing current consumption. internal voltage regulator control (INH) deactivated.

Wake-Up wake-up possible WK-pin (filtering time tWK) message (filtering time tWU) automatically transfers 6251 into standby mode sets RxD/NERR pins LOW, Figure Once 6251 been standby mode, system voltage regulator activated inhibit output INH, restarts. able detect this change switch transceiver into normal mode.
