It is designed to fulfill the requirements of ISO 11898-2 (2016) physical layer specification and respectively also the SAE standards J1939 and J2284. The TLE9250V is available in a PG-DSO-8 package and in a small, leadless PG-TSON-8 package. Both packages are RoHS compliant and halogen free. Additionally the PG-TSON-8 package supports the solder joint requirements for automated optical inspection (AOI). As an interface between the physical bus layer and the HS CAN protocol controller, the TLE9250V protects the microcontroller against interferences generated inside the network. A very high ESD robustness and the perfect RF immunity allows the use in automotive application without adding additional protection devices, like suppressor diodes for example. While the transceiver TLE9250V is not supplied the bus is switched off and illustrate an ideal passive behavior with the lowest possible load to all other subscribers of the HS CAN network. Based on the high symmetry of the CANH and CANL output signals, the TLE9250V provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE9250V fulfills even stringent EMC test limits without additional external circuit, like a common mode choke for example. The perfect transmitter symmetry combined with the optimized delay symmetry of the receiver enables the TLE9250V to support CAN FD data frames. Depending on the size of the network and the along coming parasitic effects the device supports bit rates up to 5 MBit/s. Fail-safe features like overtemperature protection, output current limitation or the TxD time-out feature protect the TLE9250V and the external circuitry from irreparable damage.

Data Sheet 5 Rev. 1.0 2017-08-09 HS CAN Transceiver High Speed CAN Transceiver High-speed CAN functional description 4 High-speed CAN functional description HS CAN is a serial bus system that connects microcontrollers, sensors and actuators for real-time control applications. The use of the Controller Area Network (abbreviated CAN) within road vehicles is described by the international standard ISO 11898. According to the 7-layer OSI reference model the physical layer of a HS CAN bus system specifies the data transmission from one CAN node to all other available CAN nodes within the network. The physical layer specification of a CAN bus system includes all electrical specifications of a CAN network. The CAN transceiver is part of the physical layer specification. Several different physical layer standards of CAN networks have been developed in recent years. The TLE9250V is a high-speed CAN transceiver with a dedicated bus wake-up function as defined in the latest ISO 11898-2 HS CAN standard. 4.1 High-speed CAN physical layer VIO = VCC = TxD = TxD VIO RxD = CANH = t CANH CANL CANL = VDiff = VCC Digital supply voltage Transmitter supply voltage Transmit data input from the microcontroller Receive data output to the microcontroller Bus level on the CANH input/output Bus level on the CANL input/output Differential voltage between CANH and CANL VDiff = VCANH – VCANL t VDiff VCC “dominant” receiver threshold “recessive” receiver threshold t RxD VIO tLoop(H,L) Figure 3 Data Sheet tLoop(L,H) t High-speed CAN bus signals and logic signals 6 Rev. 1.0 2017-08-09 HS CAN Transceiver High Speed CAN Transceiver High-speed CAN functional description The TLE9250V is a high-speed CAN transceiver, operating as an interface between the CAN controller and the physical bus medium. A HS CAN network is a two wire, differential network which allows data transmission rates up to 5 MBit/s. The characteristic for a HS CAN network are the two signal states on the CAN bus: “dominant” and “recessive” (see Figure 3). The CANH and CANL pins are the interface to the CAN bus and both pins operate as an input and output. The RxD and TxD pins are the interface to the microcontroller. The pin TxD is the serial data input from the CAN controller, the RxD pin is the serial data output to the CAN controller. As shown in Figure 1, the HS CAN transceiver TLE9250V includes a receiver and a transmitter unit, allowing the transceiver to send data to the bus medium and monitor the data from the bus medium at the same time. The HS CAN transceiver TLE9250V converts the serial data stream which is available on the transmit data input TxD, into a differential output signal on the CAN bus, provided by the CANH and CANL pins. The receiver stage of the TLE9250V monitors the data on the CAN bus and converts them to a serial, single-ended signal on the RxD output pin. A logical “low” signal on the TxD pin creates a “dominant” signal on the CAN bus, followed by a logical “low” signal on the RxD pin (see Figure 3). The feature, broadcasting data to the CAN bus and listening to the data traffic on the CAN bus simultaneously is essential to support the bit-to-bit arbitration within CAN networks. The voltage levels for HS CAN transceivers are defined in ISO 11898-2. Whether a data bit is “dominant” or “recessive” depends on the voltage difference between the CANH and CANL pins: VDiff = VCANH - VCANL. To transmit a “dominant” signal to the CAN bus the amplitude of the differential signal VDiff is higher than or equal to 1.5 V. To receive a “recessive” signal from the CAN bus the amplitude of the differential VDiff is lower than or equal to 0.5 V. “Partially-supplied” high-speed CAN networks are those where the CAN bus nodes of one common network have different power supply conditions. Some nodes are connected to the common power supply, while other nodes are disconnected from the power supply and in power-down state. Regardless of whether the CAN bus subscriber is supplied or not, each subscriber connected to the common bus media must not interfere with the communication. The TLE9250V is designed to support “partially-supplied” networks. In power-down state, the receiver input resistors are switched off and the transceiver input has a high resistance. For permanently supplied ECU's, the HS CAN transceiver TLE9250V provides a Power-save mode. In Powersave mode, the power consumption of the TLE9250V is optimized to a minimum. The voltage level on the digital input TxD and the digital output RxD is determined by the power supply level at the VIO pin. Depending on the voltage level at the VIO pin, the signal levels on the logic pins (STB, TxD and RxD) are compatible with microcontrollers having a 5 V or 3.3 V I/O supply. Usually the digital power supply VIO of the transceiver is connected to the I/O power supply of the microcontroller (see Figure 15). Data Sheet 7 Rev. 1.0 2017-08-09 HS CAN Transceiver High Speed CAN Transceiver Modes of operation 5 Modes of operation The TLE9250V supports three different modes of operation (see Figure 4 and Table 2): • Normal-operating mode • Power-save mode • Forced-receive-only mode Mode changes are either triggered by the mode selection input pin NEN or by an undervoltage event on the transmitter supply VCC. An undervoltage event on the digital supply VIO powers down the TLE9250V.

All functions are active (see also Figure 4 and Table 2): • The transmitter is active and drives the serial data stream on the TxD input pin to the bus pins CANH and CANL. • The normal-mode receiver is active and converts the signals from the bus to a serial data stream on the RxD output. • The RxD output pin indicates the data received by the normal-mode receiver. • The bus biasing is connected to VCC/2. • The NEN input pin is active and changes the mode of operation. • The TxD time-out function is enabled and disconnects the transmitter in case a time-out is detected. • The overtemperature protection is enabled and disconnects the transmitter in case an overtemperature is detected. • The undervoltage detection on VCC is enabled and triggers a mode change to Forced-receive-only in case an undervoltage event is detected. • The undervoltage detection on VIO is enabled and powers down the device in case of detection. Normal-operating mode is entered from Power-save mode and Forced-receive-only mode, when the NEN input pin is set to logical “low”. Normal-operating mode can only be entered when all supplies are available: • The transmitter supply VCC is available (VCC > VCC(UV,R)). • The digital supply VIO is available (VIO > VIO(UV,R)). 5.2 Forced-receive-only mode The Forced-receive-only mode is a fail-safe mode of the TLE9250V, which will be entered when the transmitter supply VCC is not available . The following functions are available (see also Figure 4 and Table 2): • The transmitter is disabled and the data available on the TxD input is blocked. • The normal-mode receiver is enabled. • The RxD output pin indicates the data received by the normal-mode receiver. • The bus biasing is connected to GND. • The NEN input pin is active and changes the mode of operation to Power-save mode, if logical “high”. • The TxD time-out function is disabled. • The overtemperature protection is disabled. • The undervoltage detection on VCC is active. • The undervoltage detection on VIO is enabled and powers down the device in case of detection. • Forced-receive-only mode is entered from power-down state if the NEN input pin is set to logical “low” and the digital supply VIO is available (VIO > VIO(UV,R)). • Forced-receive-only mode is entered from Normal-operating mode by an undervoltage event on the transmitter supply VCC. 5.3 Power-save mode In Power-save mode the transmitter and receiver are disabled. (see also and Table 2): • The transmitter is disabled and the data available on the TxD input is blocked. • The receiver is disabled and the data available on the bus is blocked. Data Sheet 9 Rev. 1.0 2017-08-09 HS CAN Transceiver High Speed CAN Transceiver Modes of operation • The RxD output pin is permanently set to logical “high”. • The bus biasing is floating. • The NEN input pin is active and changes the mode of operation to Normal-operating mode, if logical “low” and VCC (VCC > VCC(UV,R)) is available. • The overtemperature protection is disabled. • The undervoltage detection on VCC is disabled. In Power-save mode the device can operate without the transmitter supply VCC. • The undervoltage detection on VIO is enabled and powers down the device in case of detection. 5.4 Power-down state Independent of the transmitter supply VCC and NEN input pin the TLE9250V is powered down if the supply voltage VIO < VIO(UV,R) (see Figure 4). In the power-down state the differential input resistors of the receiver are switched off. The CANH and CANL bus interface of the TLE9250V is floating and acts as a high-impedance input with a very small leakage current. The high-ohmic input does not influence the “recessive” level of the CAN network and allows an optimized EME performance of the entire HS CAN network. In power-down state the transceiver is an invisible node to the bus.

After powering up, the device enters one out of three operating modes (see Figure 5 and Figure 6). Depending on the condition of the transmitter supply voltage VCC and the mode selection pin NEN the device can enter every mode of operation after the power-up: • VCC is available and the NEN input is set to “low” - Normal-operating mode • The NEN input is set to “high” - Power-save mode • VCC is disabled and the NEN input is set to “low” - Forced-receive-only mode The device TLE9250V powers down when the VIO supply falls below the undervoltage detection threshold (VIO < VIO(U,F)), regardless if the transmitter supply VCC is available or not. The power-down detection is active in every mode of operation.

By default the NEN input pin is logical “high” due to the internal pull-up current source to VIO. Changing the NEN input pin to logical “low” in Power-save mode triggers a mode change to Normal-operating mode (see Figure 7). To enter Normal-operating mode the transmitter supply VCC needs to be available. Power-save mode can be entered from Normal-operating mode and from Forced-receive-only mode by setting the NEN pin to logical “high”. Entering Forced-receive-only mode from Power-save mode is not possible by the NEN pin. The device remains in Power-save mode independently of the VCC supply voltage.

To avoid any interference with the network the TLE9250V blocks the transmitter and changes the mode of operation when an undervoltage event is detected (see Figure 8 and Figure 9). In Normal-operating mode a undervoltage event on transmitter supply VCC (VCC < VCC(U/F)) triggers a mode change to Forced-receive-only mode.

A current limiting circuit protects the transceiver against damages. If the device is heating up due to a continuous short on the CANH or CANL, the internal overtemperature protection switches off the bus transmitter. 7.2 Unconnected logic pins All logic input pins have an internal pull-up current source to VIO. In case the VIO and VCC supply is activated and the logical pins are open, the TLE9250V enters into the Power-save mode by default. 7.3 TxD time-out function The TxD time-out feature protects the CAN bus against permanent blocking in case the logical signal on the TxD pin is continuously “low”. A continuous “low” signal on the TxD pin might have its root cause in a lockedup microcontroller or in a short circuit on the printed circuit board, for example. In Normal-operating mode, a logical “low” signal on the TxD pin for the time t > tTxD enables the TxD time-out feature and the TLE9250V disables the transmitter (see Figure 10). The receiver is still active and the data on the bus continues to be monitored by the RxD output pin. TxD t t > tTxD TxD time-out CANH CANL TxD time–out released t RxD t Figure 10 TxD time-out function Figure 10 illustrates how the transmitter is deactivated and activated again. A permanent “low” signal on the TxD input pin activates the TxD time-out function and deactivates the transmitter. To release the transmitter after a TxD time-out event, the TLE9250V requires a signal change on the TxD input pin from logical “low” to logical “high”. Data Sheet 14 Rev. 1.0 2017-08-09 HS CAN Transceiver High Speed CAN Transceiver Fail safe functions 7.4 Overtemperature protection The TLE9250V has an integrated overtemperature detection to protect the TLE9250V against thermal overstress of the transmitter. The overtemperature protection is only active in Normal-operating mode. In case of an overtemperature condition, the temperature sensor will disable the transmitter while the transceiver remains in Normal-operating mode. After the device has cooled down the transmitter is activated again (see Figure 11). A hysteresis is implemented within the temperature sensor.

During the mode change from Power-save mode to non-low power mode the RxD output pin is permanently set to logical “high” and does not reflect the status on the CANH and CANL input pins. After the mode change is completed, the transceiver TLE9250V releases the RxD output pin.
