Description

The TLE9251V is the latest Infineon high-speed CAN transceiver generation, used inside HS CAN networks for automotive and also for industrial applications. 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 TLE9251V 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. 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 TLE9251V protects the microcontroller against interferences generated inside the network. A very high ESD robustness and the perfect RF immunity allows the use in automotive applications without adding additional protection devices, like suppressor diodes for example. While the transceiver TLE9251V is not supplied the bus is switched off and illustrates 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 TLE9251V provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE9251V fulfills even stringent EMC test limits without additional external circuit, like a common mode choke for example. The perfect transmitter symmetry comb ined with the optimized delay symm etry of the receiver enables the TLE9251V 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. Dedicated low-power modes, like Stand-by mode prov ide very low quiescent curr ents while the device is powered up. In Stand-by mode the typical quiescent current on VIO is below 10 µA while the device can still be woken up by a bus signal on the HS CAN bus. Fail-safe features like overtemperat ure protection, output current limita tion or the TxD time-out feature protect the TLE9251V and the external circuitry from irreparable damage.

5 High-speed CAN functional description

HS CAN is a serial bus system that connects microcon trollers, 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 specificatio n. Several different physical layer standards of CAN networks have been developed in recent years. The TLE 9251V is a high-speed CAN transceiver with a dedicated bus wake-up function as defined in the latest ISO 11898-2 HS CAN standard.

Datasheet 9 Rev. 1.11 2019-09-19 High Speed CAN Transceiver TLE9251V High-speed CAN functional description The TLE9251V 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 CA N 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 bu s 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 cont roller. As shown in Figure 1, the HS CAN transceiver TLE9251V 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 TLE9251V 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 TLE9251V 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 da ta to the CAN bus and listenin g 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 tran sceivers 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 th ose 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 in the communication. The TLE9251V is design ed 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 EC U's, the HS CAN transceiver TLE9251V pr ovides a Stand-by mode. In Stand-by mode, the power consumption of the TLE9251V is optimize d to a minimum, while the device is still able to recognize wake-up patterns on the CAN bus and signal the wake-up event to the external microcontroller. The voltage level on the digital input TxD and the digita l 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 18).

Datasheet 10 Rev. 1.11 2019-09-19 High Speed CAN Transceiver TLE9251V Modes of operation

6 Modes of operation

The TLE9251V supports three different modes of operation (see Figure 4 and Table 5):

• Normal-operating mode
• S t a n d - b y m o d e
• F o r c e d - r e c e i v e - o n l y m o d e Mode changes are either triggered by the mode selectio n input pin STB or by an undervoltage event on the transmitter supply V CC. Wake-up events on the HS CAN bus are indicated on the RxD output pin in Stand-by mode, but no mode change is triggered by a wake-up event. An undervoltage event on the digital supply VIO powers down the TLE9251V.

Datasheet 11 Rev. 1.11 2019-09-19 High Speed CAN Transceiver TLE9251V Modes of operation

6.1 Normal-operating mode

In Normal-operating mode the transceiver TLE9251V sends and receives data from the HS CAN bus. All functions are active (see also Figure 4 and Table 5):

• 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 low-power receiver is turned off.
• The RxD output pin indicates the data received by the normal-mode receiver.
• The bus biasing is connected to V CC/2.
• The STB input pin is active and changes the mode of operation.
• The TxD time-out function is enabled and disconnect s the transmitter in case a time-out is detected.
• The overtemperature protection is enabled and discon nects the transmitter in case an overtemperature is detected.
• The undervoltage detection on V CC 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 Stand-by mo de and Forced-receive-only mode, when the STB 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)).

6.2 Forced-receive-only mode

The Forced-receive-only mode is a fail-safe mode of the TLE9251V, which will be entered when the transmitter supply VCC is not available and the STB pin is logical “low ”. The following functions are available (see also Figure 4 and Table 5):

• The transmitter is disabled and the data available on the TxD input is blocked.
• T h e n o r m a l - m o d e r eceiver is enabled.
• The low-power receiver is turned off.
• The RxD output pin indicates the data received by the normal-mode receiver.
• The bus biasing is connected to GND.
• The STB input pin is active and changes the mode of operation to Stand-by 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 STB input pin is set to logical “low” and the digital supply VIO is available (VIO > VIO(UV,R)).
• Forced-receive-only mode is ente red from Normal-operating mode by an undervoltage event on the transmitter supply VCC.

6.3 Stand-by mode

The Stand-by mode is the power save mode of the TL E9251V. In Stand-by mode most of the functions are turned off and the TLE9251V is monitoring the bus for a valid wake-up pattern (WUP). The following functions are available (see also Figure 4 and Table 5):

• The transmitter is disabled and the data available on the TxD input is blocked.
• The normal-mode receiver is disabled.
• The low-power receiver is turned on and monitors the bus for a valid wake-up pattern (WUP).
• The RxD output pin follows the Bus signal after WUP detection.
• The bus biasing is connected to GND.
• The STB input pin is active and changes the mode of operation.
• The TxD time-out function is disabled.
• The overtemperature protection is disabled.
• The undervoltage detection on V CC is disabled. In Stand-by 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. The Stand-by mode can be entered from Normal-opera ting mode and Forced-receive-only mode by setting the STB pin to logical “high”. To enter Stand-by mode the digital supply VIO needs to be available (VIO > VCC(UV,R)).

6.4 Power-down state

Independent of the transmitter supply VCC and of the status at STB input pin the TLE9251V is powered down if the supply voltage VIO < VIO(UV,F) (see Figure 4). In the power-down state the differential input resistor s of the receiver are switch ed off. The CANH and CANL bus interface of the TLE9251V 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 netw ork. In power-down state the transc eiver is an invisible node to the bus.

7 Changing the mode of operation

7.1 Power-up and power-down

The HS CAN transceiver TLE9251V powers up by applying the digital supply VIO to the device ( VIO > VIO(U,R)). 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 STB the device can enter every mode of operation after the power-up:

• VCC is available and STB input is set to “low” - Normal-operating mode
• VCC is disabled and the STB input is set to “low” - Forced -receive-only mode
• STB input is set to “high” - Stand-by mode The device TLE9251V 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.

7.2 Mode change by the STB pin

When the TLE9251V is supplied with the digital voltage VIO the internal logic works and mode change by the mode selection pin STB is possible. By default the STB input pin is logical “high” due to the internal pull-up current source to VIO. Changing the STB input pin to logical “low” in Stand-by 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. Stand-by mode can be entered from Normal-operating mode and Forced-receive-o nly mode by setting the STB pin to logical “high”. While changing the mode of operation from Normal-ope r a t i n g m o d e o r F o r c e d - receive-only mode to Stand-by mo de, the transceiver TLE9251V turns of f the transmitter and switches from the normal-mode receiver to the low-power receiver . Entering Forced-receive -only mode from Stand-by mode is not possible by the STB pin. The device remains in Stand-by mode independently of the VCC supply voltage.

7.3 Mode changes by VCC undervoltage

When the transmitter supply VCC (VCC < VCC(U/F)) is in undervoltage condition, the TLE9251V might not be able to provide the correct bus levels on the CANH and CANL output pins. To avoid any interference with the network the TLE9251V blocks the transmitter and changes the mode of operatio n when an undervoltage event is detected (see Figure 8 and Figure 9). In Normal-operating mode an underv oltage event on transmitter supply VCC (VCC < VCC(U/F)) triggers a mode change to Forced-receive-only mode. In Forced-receive-only mode the undervoltage detection VCC (VCC < VCC(U/F)) is enabled. In Stand-by mode the undervoltage detection is disabled. In these modes the TLE9251V can operate without the transmitter supply VCC.

7.4 Remote wake-up

The TLE9251V has a remote wake-up feature also call ed bus wake-up feature ac cording to the ISO 11898-2 (2016). In Stand-by mode the low-power receiver monitors the activity on the CAN bus and in case it detects a wake-up pattern it indicates the wake-up signal on the RxD output pin. The low-power receiver is supp lied by the digital supply VIO and therefore in Stand-by mode the transmitter supply VCC can be turned off. In Stand-by mode a wake-up event on the HS CAN is flagged on the RxD output pin (see Figure 11). The transceiver remains in the currently selected mode of operation. No mode change is applied due to the wake- up event (see Figure 10). Figure 10 Remote wake-up A bus wake-up is triggered by a dedicated valid wake -up pattern. The defined wake-up pattern avoids any false wake-up by spikes which might be on the HS CAN bus or by a permanent bus shortage. The internal wake-up flag will be reset when:

• A mode change to Normal-operating mode is applied during the wake-up pattern.
• A power-down event occurs on the digital supply V IO. Within the maximum wake-up time tWAKE, the wake-up pattern contents a dominant signal with the pulse width tFilter, followed by a recessive signal with the pulse width tFilter and another dominant signal with the pulse width tFilter (see Figure 11). The RxD output remains logical “hig h” as long no wake-up event has been detected.

Datasheet 18 Rev. 1.11 2019-09-19 High Speed CAN Transceiver TLE9251V Fail safe functions

8 Fail safe functions

8.1 Short circuit protection

The CANH and CANL bus pins are proven to cope with a short circuit fault against GND and against the supply voltages. 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 ov ertemperature protection switches off the bus transmitter.

8.2 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 TLE9251V enters into the Stand-by mode by default.

8.3 TxD time-out function

The TxD time-out feature protects th e 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 locked- up 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 TLE9251V disables the transmitter (see Figure 13). The receiver is still active and the data on the bus continues to be monitored by the RxD output pin. Figure 13 TxD time-out function Figure 13 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 TLE9251V requires a sign al change on the TxD input pin from logical “low” to logical “high”.

8.4 Overtemperature protection

The TLE9251V has an integrated overtemperature detection to protect the TLE9251V against thermal overstress of the transmitter. The overtemperature prot ection is only active in Normal-operating mode. In TxD t t CANH CANL RxD t TxD time-out TxD time–out releasedt > tTxD

Datasheet 19 Rev. 1.11 2019-09-19 High Speed CAN Transceiver TLE9251V Fail safe functions case of an overtemperature condition, the temper ature 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 14). A hysteresis is implemented within the temperature sensor. Figure 14 Overtemperature proctection

8.5 Delay time for mode change

The HS CAN transceiver TLE9251V changes the mo de of operation within the time window tMode. During the mode change from Stand-by mode to non-low power mo de 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 TLE9251V releases the RxD output pin. TxD t t CANH CANL RxD t TJ t TJSD (shut down temperature) switch-on transmitter ΔT cool down
