Figure 2 shows the principle configuration of a CAN network. The IFX1054G is optimized for low-speed data transmission (up to 125 kBaud) in industrial applications. In Normal operation mode a differential signal is transmitted / received. When bus wiring failures are detected the device automatically switches in a dedicated single-wire mode to maintain communication. While no data is transferred, the power consumption can be minimized by multiple low power operation modes. Further a Receive - Only mode is implemented. To reduce radiated electromagnetic emission (EME) the dynamic slopes of the CANL and CANH signals are both limited and symmetric. This allows the use of an unshielded twisted or parallel pair of wires for the bus. During single-wire transmission (one of the bus lines is affected by a bus line failure) the EME performance of the system is degraded from the differential mode. In case the transmission data input TxD is permanently dominant, both, the CANH and CANL transmitting stage are disabled after a certain delay time. This is necessary to prevent the bus from being blocked by a defective protocol unit or short to GND at the TxD input.

Via the control input pins NSTB and ENT the operation modes are selected by the microcontroller. In the Low - Power modes neither receiving nor transmitting of messages is possible. In Sleep operation mode the lowest power consumption is achieved. In order to minimize the overall current consumption of the ECU (electronic control unit) the external voltage regulator (5 V supply) is deactivated by the INH output in this mode, when connected. For that purpose the INH output is switched to high impedance. In parallel the CANL line is pulled - up to the battery supply voltage via the RTL output and the pull - up paths at the input pins TxD and RxD are disabled from the internal supply. To enter the Sleep operation mode the transition mode “Go - to - Sleep” has to be selected (Figure 2) for a minimum time th(min). After the minimum hold time th(min) the Sleep mode can be actively selected. Otherwise the IFX1054G will automatically fall in Sleep mode because of the not powered microcontroller. On a Wake - Up request either by bus line activities or via the WK input, the transceiver is automatically set in VBAT Stand - By mode. Now the voltage regulator (5 V supply) is enabled by the INH output. The WK input reacts to both, transition from high to low voltage level as well as the other way round. To avoid faulty Wake - Up’s due to transients on the bus lines or the WK input circuitry respectively, a certain filter time is implemented. As soon as VCC is provided, the Wake - Up request is monitored on both, the NERR and RxD outputs, by setting them low. Upon this the microcontroller can activate the Normal operation mode by setting the control inputs NSTB and ENT high. The VBAT Stand - By mode corresponds to the Sleep mode, but a voltage regulator connected to the INH output will remain active. Wake - Up requests via the WK pin or the bus lines are immediately reported to the microcontroller by setting RxD and NERR low. A power - on condition (VBAT pin is supplied) automatically switches the IFX1054G to VBAT Stand - By mode. In the Receive - Only mode data on the CAN-bus is transferred to the RxD output, but both output stages, CANH as well as CANL are disabled. This means that data at the TxD input is not transmitted to the CAN bus. This mode is useful in combination to a dedicated network - management software that allows separate diagnosis for all nodes. A Wake - Up request in the Receive - Only mode is only reported at the RxD-output. The NERR output in this mode is used to indicate a battery fail condition. When entering the Normal mode the VBAT-flag is reset and the NERR output becomes high again. This feature is useful e.g. when changing the ECU and therefore a presetting routine of the microcontroller has to be started. If either of the supply voltages drops below the specified limits, the transceiver is automatically switched to VBAT Stand - By mode or power - down mode respectively.

Therefore, the device is equipped with one differential receiver and 4 single ended receivers, two for each bus line. To avoid false triggering by external RF influences the single wire modes are only activated after a certain delay time. As soon as the bus failure disappears the transceiver switches back to differential mode after another time delay. Bus failures are indicated in the Normal operation mode by setting the NERR output low. The differential receiver threshold is typ. -3.1 V. This ensures correct reception in the Normal operation mode as well as in the failure cases 1, 2 and 4 with a noise margin as high as possible. For these failures, further failure management is not necessary. Detection of the failure cases 1, 2, 3a and 4 is only possible when the bus is dominant. Nevertheless, they are reported on the NERR output until transmission of the next CAN word on the bus begins. When one of the bus failures 3, 5, 6, 6a and 7 is detected, the defective bus wire is disabled by switching off the affected bus termination and the respective output stage. A Wake - Up from Sleep mode via the bus is possible either via a dominant CANH or CANL line. This ensures that a Wake - Up is possible even if one of the failures 1 to 7 occurs.

The CANH and CANL pins are protected against electrical transients. The transmitter output stages generate the majority of the power dissipation. Therefore they are disabled if the junction temperature exceeds the maximum value. This effectively reduces power dissipation, and hence will lead to a lower chip temperature, while other parts of the IC can remain operating. In temperature shut - down condition the IFX1054G is still able to receive CAN-bus messages. 4.2 Application Hints Table 3 Not Needed Pins Pin Symbol Recommendation INH Leave open NERR Leave open NSTB Connect to VCC ENT Connect to VCC WK Connect to VBAT, connect to GND: increases current consumption by approx. 5 µA Data Sheet 10 Rev. 1.0, 2009-05-12 IFX1054G Absolute Maximum Ratings 5 Absolute Maximum Ratings Table 4 Absolute Maximum Ratings Parameter Symbol Input voltage at VBAT Logic supply voltage VCC Input voltage at TxD, RxD, NERR, NSTB and ENT Input voltage at CANH and CANL Transient voltage at CANH and CANL Input voltage at WK Input voltage at INH Input voltage at RTH and RTL Junction temperature Storage temperature Electrostatic discharge voltage at pin CANH, CANL, RTH, RTL, VBAT Electrostatic discharge voltage at any other pin Limit Values Unit Notes Min.

The capacitors C1-2 simulate the cable. Allowed minimum values of the termination resistors RRTH and RRTL are 500 Ω. Electromagnetic interference on the bus lines is simulated by switching to CAN Bus Substitute 2. The waves of the applied transients will be in accordance with ISO 7637 part 1, test 1, test pulses 1, 2, 3a and 3b.
