9250X
The TLE9250X 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 TLE9250X 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 TLE9250X 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 TLE9250X 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 TLE9250X provides a very low level of
electromagnetic emission (EME) within a wide frequency range. The TLE9250X 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
TLE9250X 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 TLE9250X and the external circuitry from irreparable damage.

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 TLE9250X is a high-speed CAN
transceiver with a dedicated bus wake-up function as defined in the latest ISO 11898-2 HS CAN standard.

HS CAN Transceiver
High Speed CAN Transceiver
High-speed CAN functional description
The TLE9250X 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 TLE9250X 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 TLE9250X
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 TLE9250X 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 TLE9250X 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.
.
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).

Modes of operation
The TLE9250X supports three different modes of operation (see Figure 4 and Table 2):
•
Normal-operating mode
•
Receive-only mode
•
Forced-receive-only mode
Mode changes are either triggered by the mode selection input pin RM or by an undervoltage event on the
transmitter supply VCC. An undervoltage event on the digital supply VIO powers down the TLE9250X.

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 TLE9250X, 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.
•
A mode change by setting the RM input pin logical to “high” or “low” does not change the mode of
operation.
•
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.

5.4
Power-down state
Independent of the transmitter supply VCC and RM input pin the TLE9250X 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 TLE9250X 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.

Power-up and power-down
The HS CAN transceiver TLE9250X 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 RM the device
can enter every mode of operation after the power-up:
•
VCC is available and the RM input is set to “low” - Normal-operating mode
•
VCC is disabled - Forced-receive-only mode
•
VCC is available and the RM input is set to “high” - Receive-only mode
The device TLE9250X 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.

Mode change by the RM pin
When the TLE9250X is supplied with the digital voltage VIO the internal logic works and mode change by the
mode selection pin RM is possible.
By default the RM input pin is logical “low” due to the internal pull-down current source to GND. Changing the
RM input pin to logical “high” in Normal-operating mode triggers a mode change to Receive-only mode (see
Figure 7). To enter Normal-operating mode or Receive-only mode the transmitter supply VCC needs to be
available.

Mode changes by VCC undervoltage
When the transmitter supply VCC (VCC < VCC(U/F)) is in undervoltage condition, the TLE9250X 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 TLE9250X 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 and in Receive-only mode a undervoltage event on 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 this mode the
TLE9250X can operate without the transmitter supply VCC.
Due to the internal pull-down current source at RM input pin the transceiver changes the mode of operation
from Forced-receive-only mode to Normal-operating mode if VCC is supplied again and no external signal is
applied to the RM input pin.

Fail safe functions

Fail safe functions
7.1
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 overtemperature protection switches off the bus
transmitter.
7.2
Unconnected logic pins
The RM input pin has an internal pull-down current source to GND. All other 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
TLE9250X enters into the Normal-operating 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 TLE9250X 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.

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 TLE9250X requires a signal change on the TxD input pin from logical “low” to
logical “high”.

Overtemperature protection
The TLE9250X has an integrated overtemperature detection to protect the TLE9250X 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.
