TLE9350SJ

High speed CAN FD transceiver

Based on the high symmetry of the CANH and CANL output signals, the TLE9350SJ provides a very low level of

electromagnetic emission (EME) within a wide frequency range. The TLE9350SJ fulfills even stringent EMC test

limits without an additional external circuit, such as a common mode choke.

The optimized transmitter symmetry combined with the optimized delay symmetry of the receiver enables

the TLE9350SJ to support CAN FD data frames. The device supports data transmission rates up to 5 MBit/s,

depending on the size of the network and the inherent parasitic effects.

Fail-safe features, such as overtemperature protection, output current limitation or the TxD time-out feature

are designed to protect the TLE9350SJ and the external circuitry from irreparable damage.

High speed CAN FD transceiver

High speed CAN functional description

HS CAN is a serial bus system that connects microcontrollers, sensors and actuators for real-time control

applications. ISO 11898 describes the use of the controller area network (CAN) within road vehicles. 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 CAN nodes available within the network. The physical layer specification of a

CAN bus system includes all electrical specifications of a CAN. The CAN transceiver is part of the physical layer

specification.

TLE9350SJ

High speed CAN FD transceiver

The TLE9350SJ operates as an interface between the CAN controller and the physical bus medium. A HS CAN

is a two wire differential network which allows data transmission rates up to 5 MBit/s. The characteristics for

a HS CAN 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

simultaneously. 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 TLE9350SJ 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 TLE9350SJ 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 TLE9350SJ monitors the data on the CAN bus

and converts them to a serial, single-ended signal on the RxD output pin. A "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

of 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.

ISO 11898-2:2016 specifies the voltage levels for HS CAN transceivers. Whether a data bit is dominant or

recessive depends on the voltage difference between the CANH and CANL pins (V_Diff= V_CANH- V_CANL).

To transmit a dominant signal to the CAN bus the amplitude of the differential signal V_Diffis higher than or

equal to 1.5 V. To receive a recessive signal from the CAN bus the amplitude of the differential V_Diffis lower than

or equal to 0.5 V.

In partially-supplied high speed CAN the bus nodes of one common network have different power supply

conditions. Some nodes are connected to the 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 TLE9350SJ

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 ECUs, the HS CAN transceiver TLE9350SJ provides a power-save mode. In power-

save mode, the power consumption of the TLE9350SJ 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 V_CCpin. Depending on the voltage level at the V_CCpin, the signal levels on the logic pins (STB, TxD and

RxD) are compatible with microcontrollers having a 5 V I/O supply.

Normal-operating mode

In normal-operating mode all functions of the device are available and the device is fully functional. Data can

be received from the HS CAN bus as well as transmitted to the HS CAN bus.

•

The transmitter is enabled and drives the serial data stream on the TxD input pin to the bus pins CANH

and CANL

•

The receiver is enabled and converts the signal from the bus to a serial data stream on the RxD output pin

The bus biasing is active

The TxD time-out function is enabled (see Chapter 6.4)

The overtemperature protection is enabled (see Chapter 6.6)

The undervoltage detection on V_CCis enabled (see Chapter 6.3)

The device enters normal-operating mode by setting the mode selection pins NEN to "low" and NRM to "high",

see Figure 4. Normal-operating mode can be entered if the device supply V_CCis higher than V_{CC_UV_R}. The

device enters normal-operating mode after t_modeexpires.

Note:

If the device recognizes a recessive signal on the TxD input pin during a mode change from any mode

to normal-operating mode, then it enables the transmit path after the mode change.

TLE9350SJ

High speed CAN FD transceiver

If the device recognizes a a dominant signal on the TxD input pin during a mode change to normal-

operating mode, then it keeps the transmit path disabled and it blocks the dominant signal in order

to not disturb the bus communication . As soon as the device recognizes a recessive signal on the TxD

input pin, it enables the transmit path again.

5.2

Receive-only mode

In receive-only mode the transmitter is disabled and the receiver is enabled. The TLE9350SJ can receive data

from the HS CAN bus, but cannot transmit data to the HS CAN bus.

•

The transmitter is disabled and the data available on the TxD input is blocked

The receiver is enabled and converts the signal from the bus to a serial data stream on the RxD output pin

The bus biasing is connected to V_CC/2 for V_CC> V_{CC_UV}

The TxD time-out function is disabled.

The undervoltage detection on V_CCis enabled (see Chapter 6.3)

If the mode selection pin NRM is set to "low" while NEN is set to "low", then the TLE9350SJ enters receive-only.

V_CCmust be higher than V_{CC_UV}as a prerequisite to enter receive-only mode. The device enters receive-only

mode after t_modeexpires.

5.3

Power-save mode

In power-save mode the transmitter and receiver are disabled (see also Figure 4):

•

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

The RxD output pin is permanently set to logical "high"

The bus biasing is connected to high impedance

The NEN and NRM input pins are active and change the mode of operation to normal-operating mode or

receive-only mode

•

The overtemperature protection is disabled

The undervoltage detection on V_CCis enabled

Power-save mode can be entered from normal-operating mode or receive-only mode by setting the NEN pin

to logical "high". The device enters this mode after t_modeexpires or after the period of t_PONwhen coming from

power-down state.

If the supply voltage V_CC< V_{CC_UV_F}, then the device powers down independent of NRM and NEN input pins (see

Figure 5). In power-down state all functions of the device are disabled and the device is switched off. The

input resistors of the receiver are disconnected. The CANH and CANL bus interface of the device is floating and

acts as a high impedance input with a very low leakage current. The high impedance input does not influence

the recessive level of the CAN and allows an optimized EME performance of the entire network. In power-down

state the transceiver is an invisible node to the bus. t_ponmust expire as a prerequisite for the device to exit

power-down state.

Fail safe functions

6.1

Short circuit protection

The CANH and CANL bus outputs are short circuit proof to GND and short circuit proof to a supply voltage. The

current limiting circuit is designed to protect the transceiver from damage. If the device heats up due to a

continuous short on the CANH or CANL, then the internal overtemperature protection switches off the bus

transmitter.

6.2

Unconnected logic pins

All logic input pins have an internal pull-up resistor to V_CC. If the V_CCsupply is active and the logical pins are

open, the device enters the power-save mode by default.

6.3

V_CCundervoltage

If the transceiver supply is in undervoltage condition V_CC< V_{CC_UV_F}for longer than t_{VCC_UV_Filter}, then the device

switches to power-down mode (see Figure 5).

6.4

TxD time-out feature

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 locked-

up microcontroller or in a short circuit on the printed circuit board, for example.

In normal-operating mode, a "low" signal on the TxD pin for the time t > t_TxDenables the TxD time-out feature

and the device disables the transmitter (see Figure 6). The receiver is still active and the device continues to

monitor data on the bus via the RxD output pin.

Figure 6

TxD time-out function

Figure 6 shows how the transmitter is deactivated and activated again. A permanent "low" signal on the TxD

input pin activates the TxD time-out and deactivates the transmitter. To release the transmitter after a TxD

time-out event, the device requires a signal change on the TxD input pin from "low" to "high".

6.5

Delay time for mode change

The device changes the mode of operation within the time window t_Mode. During the mode change from

power-save mode to non-low power mode the device sets the RxD output "high" permanently, so it does not

reflect the status on the CANH and CANL input pins.

After the mode change is completed, the device releases the RxD output pin.

6.6

Overtemperature protection

The TLE9350SJ has an integrated overtemperature detection, which is designed to protect the device 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 disables the transmitter while the

transceiver remains in normal-operating mode. After the device cools down it enables the transmitter again

(see Figure 7). A hysteresis is implemented within the temperature sensor.
