Overview
electromagnetic emission (EME) within a wide frequency range.
The TLE8250VSJ fulfills or exceeds the requirements of the ISO11898-2.
The TLE8250VSJ provides a digital supply input VIO and a power-save mode. It is designed to fulfill the
enhanced physical layer requirements for CAN FD and supports data rates up to 2 MBit/s.
On the basis of a very low leakage current on the HS CAN bus interface the TLE8250VSJ provides an excellent
passive behavior in power-down state. These and other features make the TLE8250VSJ exceptionally suitable
for mixed supply HS CAN networks.
Based on the Infineon Smart Power Technology SPT, the TLE8250VSJ provides excellent ESD immunity
together with a very high electromagnetic immunity (EMI). The TLE8250VSJ and the Infineon SPT technology
are AEC qualified and tailored to withstand the harsh conditions of the automotive environment.
Two different operating modes, additional fail-safe features like a TxD time-out and the optimized output
slew rates on the CANH and CANL signals, make the TLE8250VSJ the ideal choice for large HS CAN networks
with high data transmission rates.

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 and mechanical
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 TLE8250VSJ is a
High Speed CAN transceiver without a wake-up function and defined by the international standard ISO 118982.

TLE8250V
High Speed CAN Transceiver
Functional Description
The TLE8250VSJ 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 for CAN FD frames up to 2 MBit/s. Characteristic for HS CAN networks are the two signal states on the
HS CAN bus: dominant and recessive (see Figure 3).
VCC, VIO and GND are the supply pins for the TLE8250VSJ. The pins CANH and CANL are the interface to the
HS CAN bus and operate in both directions, as an input and as an output. RxD and TxD pins are the interface
to the CAN controller, the TxD pin is an input pin and the RxD pin is an output pin. The NEN pin is the input pin
for the mode selection (see Figure 4).
By setting the TxD input pin to logical “low” the transmitter of the TLE8250VSJ drives a dominant signal to the
CANH and CANL pins. Setting TxD input to logical “high” turns off the transmitter and the output voltage on
CANH and CANL discharges towards the recessive level. The recessive output voltage is provided by the bus
biasing (see Figure 1). The output of the transmitter is considered to be dominant, when the voltage difference
between CANH and CANL is at least higher than 1.5 V (VDiff = VCANH - VCANL).
Parallel to the transmitter the normal-mode receiver monitors the signal on the CANH and CANL pins and
indicates it on the RxD output pin. A dominant signal on the CANH and CANL pins sets the RxD output pin to
logical “low”, vice versa a recessive signal sets the RxD output to logical “high”. The normal-mode receiver
considers a voltage difference (VDiff) between CANH and CANL above 0.9 V as dominant and below 0.5 V as
recessive.
To be conform with HS CAN features, like the bit to bit arbitration, the signal on the RxD output has to follow
the signal on the TxD input within a defined loop delay tLoop ≤ 255 ns.
The thresholds of the digital inputs (TxD and NEN) and also the RxD output voltage are adapted to the digital
power supply VIO.

Modes of Operation
The TLE8250VSJ supports two different modes of operation, power-save mode and normal-operating mode
while the transceiver is supplied according to the specified functional range. The mode of operation is
selected by the NEN input pin (see Figure 4).

Mode state diagram
Normal-operating Mode
In normal-operating mode the transmitter and the receiver of the HS CAN transceiver TLE8250VSJ are active
(see Figure 1). The HS CAN transceiver sends the serial data stream on the TxD input pin to the CAN bus. The
data on the CAN bus is displayed at the RxD pin simultaneously. A logical “low” signal on the NEN pin selects
the normal-operating mode, while the transceiver is supplied by VCC and VIO (see Table 2 for details).
4.2.2
Power-save Mode
The power-save mode is an idle mode of the TLE8250VSJ with optimized power consumption. In power-save
mode the transmitter and the normal-mode receiver are turned off. The TLE8250VSJ can not send any data to
the CAN bus nor receive any data from the CAN bus.
The RxD output pin is permanently “high” in the power-save mode.
A logical “high” signal on the NEN pin selects the power-save mode, while the transceiver is supplied by the
digital supply VIO (see Table 2 for details).
In power-save mode the bus input pins are not biased. Therefore the CANH and CANL input pins are floating
and the HS CAN bus interface has a high resistance.
The undervoltage detection on the transmitter supply VCC is turned off, allowing to switch off the VCC supply in
power-save mode.

Power-up and Undervoltage Condition
By detecting an undervoltage event, either on the transmitter supply VCC or the digital supply VIO, the
transceiver TLE8250VSJ changes the mode of operation. Turning off the digital power supply VIO, the
transceiver powers down and remains in the power-down state. While switching off the transmitter supply VCC,
the transceiver either changes to the forced power-save mode, or remains in power-save mode (details see

TLE8250V
High Speed CAN Transceiver
Functional Description
4.3.1
Power-down State
Independent of the transmitter supply VCC and of the NEN input pin, the TLE8250VSJ is in power-down state
when the digital supply voltage VIO is turned off (see Figure 5).
In the power-down state the input resistors of the receiver are disconnected from the bus biasing VCC/2. The
CANH and CANL bus interface of the TLE8250VSJ 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 (see also Table 2).
4.3.2
Forced Power-save Mode
The forced power-save mode is a fail-safe mode to avoid any disturbance on the HS CAN bus, while the
TLE8250VSJ faces a loss of the transmitter supply VCC.
In forced power-save mode, the transmitter and the normal-mode receiver are turned off and therefore the
transceiver TLE8250VSJ can not disturb the bus media.
The RxD output pin is permanently set to logical “high”. The bus biasing is floating (details see Table 2).
The forced power-save mode can only be entered when the transmitter supply VCC is not available, either by
powering up the digital supply VIO only or by turning off the transmitter supply in normal-operating mode.
While the transceiver TLE8250VSJ is in forced power-save mode, switching the NEN input to logical “high”
triggers a mode change to power-save mode (see Figure 5).
4.3.3
Power-up
The HS CAN transceiver TLE8250VSJ powers up if at least the digital supply VIO is connected to the device. By
default the device powers up in power-save mode, due to the internal pull-up resistor on the NEN pin to VIO.
In case the device needs to power-up to normal-operating mode, the NEN pin needs to be pulled active to
logical “low” and the supplies VIO and VCC have to be connected.
By supplying only the digital power supply VIO the TLE8250VSJ powers up either in forced power-save mode
or in power-save mode, depending on the signal of the NEN input pin (see Figure 5).

Undervoltage on the Digital Supply VIO
If the voltage on VIO supply input falls below the threshold VIO < VIO(UV,F), the transceiver TLE8250VSJ powers
down and changes to the power-down state.
The undervoltage detection on the digital supply VIO has the highest priority. It is independent of the
transmitter supply VCC and also independent of the currently selected operating mode. An undervoltage event
on VIO always powers down the TLE8250VSJ.

Undervoltage on the digital supply VIO
Undervoltage on the Transmitter Supply VCC
In case the transmitter supply VCC falls below the threshold VCC < VCC(UV,F), the transceiver TLE8250VSJ changes
the mode of operation to forced power-save mode. The transmitter and also the normal-mode receiver of the
TLE8250VSJ are powered by the VCC supply. In case of an insufficient VCC supply, the TLE8250VSJ can neither
transmit the CANH and CANL signals correctly to the bus, nor can it receive them properly. Therefore the
TLE8250VSJ blocks the transmitter and the receiver in forced power-save mode (see Figure 7).
The undervoltage detection on the transmitter supply VCC is only active in normal-operating mode (see
Figure 5).

Voltage Adaption to the Microcontroller Supply
The HS CAN transceiver TLE8250VSJ has two different power supplies, VCC and VIO. The power supply VCC
supplies the transmitter and the normal-mode receiver. The power supply VIO supplies the digital input and
output buffers and it is also the main power domain for the internal logic.
To adjust the digital input and output levels of the TLE8250VSJ to the I/O levels of the external microcontroller,
connect the power supply VIO to the microcontroller I/O supply voltage (see Figure 13).
Note:
Data Sheet
In case the digital supply voltage VIO is not required in the application, connect the digital supply
voltage VIO to the transmitter supply VCC.

Fail Safe Functions
5.1
Short Circuit Protection
The CANH and CANL bus outputs are short circuit proof, either against GND or a positive supply voltage. 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.
5.2
Unconnected Logic Pins
All logic input pins have an internal pull-up resistor to VIO. In case the VIO supply is activated and the logical pins
are open, the TLE8250VSJ enters into the power-save mode by default. In power-save mode the transmitter of
the TLE8250VSJ is disabled and the bus bias is floating.
5.3
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 TLE8250VSJ
disables the transmitter (see Figure 8). The receiver is still active and the data on the bus continues to be
monitored by the RxD output pin.

Figure 8
TxD time-out function
Figure 8 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 TLE8250VSJ requires a signal change on the TxD input pin from logical “low” to
logical “high”.

Overtemperature Protection
The TLE8250VSJ has an integrated overtemperature detection to protect the TLE8250VSJ against thermal
overstress of the transmitter. The overtemperature protection is active in normal-operating mode and
disabled in power-save mode. In case of an overtemperature condition, the temperature sensor will disable
the transmitter (see Figure 1) while the transceiver remains in normal-operating mode.
After the device has cooled down the transmitter is activated again (see Figure 9). A hysteresis is implemented
within the temperature sensor.

Delay Time for Mode Change
The HS CAN transceiver TLE8250VSJ changes the mode of operation within the time window tMode. During the
mode change the RxD output pin is permanently set to logical “high” and does not reflect the status on the
CANH and CANL input pins (see as an example Figure 14 and Figure 15).

Data Sheet
Stresses above the ones listed here may cause permanent damage to the device. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability. Integrated
protection functions are designed to prevent IC destruction under fault conditions described in the
data sheet. Fault conditions are considered as “outside” normal-operating range. Protection
functions are not designed for continuos repetitive operation.

High Speed CAN Transceiver
Application Information

Examples for Mode Changes
•
The mode change is executed independently of the signal on the HS CAN bus. The CANH, CANL inputs may
be either dominant or recessive. They can be also permanently shorted to GND or VCC.
•
A mode change is performed independently of the signal on the TxD input. The TxD input may be either
logical “high” or “low”.
Analog to that, changing the NEN input pin to logical “high” changes the mode of operation to the power-save
mode independent on the signals at the CANH, CANL and TxD pins.
Note:
In case the TxD signal is “low” setting the NEN input pin to logical “low” changes the operating mode
of the device to normal-operating mode and drives a dominant signal to the HS CAN bus.
Note:
The TxD time-out is only effective in normal-operating mode. The TxD time-out timer starts when the
TLE8250VSJ enters normal-operating mode and the TxD input is set to logical “low”.

High Speed CAN Transceiver
Application Information
8.3.1
Mode Change while the TxD Signal is “low”
The example in Figure 14 shows a mode change to normal-operating mode while the TxD input is logical
“low”. The HS CAN signal is recessive, assuming all other HS CAN bus subscribers are also sending a recessive
bus signal.
While the transceiver TLE8250VSJ is in power-save mode, the transmitter and the normal-mode receiver are
turned off. The TLE8250VSJ drives no signal to the HS CAN bus nor does it receive any signal from the HS CAN
bus. Changing the NEN to logical “low” turns the mode of operation to normal-operating mode, while the TxD
input signal remains logical “low”. The transmitter and the normal-mode receiver remain disabled until the
mode transition is completed. In normal-operating mode the transmitter and the normal-mode receiver are
active. The “low” signal on the TxD input drives a dominant signal to the HS CAN bus and the RxD output
becomes logical “low” following the dominant signal on the HS CAN bus.
Changing the NEN pin back to logical “high”, disables the transmitter and normal-mode receiver again. The
RxD output pin is blocked and set to logical “high” with the start of the mode transition. The TxD input and the
transmitter are blocked and the HS CAN bus becomes recessive.
Note: The signals on the HS CAN bus are “recessive”, the “dominant” signal is
generated by the TxD input signal

Mode Change while the Bus Signal is dominant
The example in Figure 15 shows a mode change while the bus is dominant and the TxD input signal is set to
logical “high”.
While the transceiver TLE8250VSJ is in power-save mode, the transmitter and the normal-mode receiver are
turned off. The TLE8250VSJ drives no signal to the HS CAN bus nor does it receive any signal from the HS CAN
bus. Changing the NEN to logical “low” turns the mode of operation to normal-operating mode, while the TxD
input signal remains logical “high”. The transmitter and the normal-mode receiver remain disabled until the
mode transition is completed. In normal-operating mode the transmitter of TLE8250VSJ remains recessive,
because of the logical “high” signal on the TxD input. The normal-mode receiver becomes active and the RxD
output signal changes to logical “low” following the dominant signal on the HS CAN bus.
Changing the NEN pin back to logical “high”, disables the transmitter and normal-mode receiver again. The
RxD output pin is blocked and set to logical “high” with the start of the mode transition.
Note: The “dominant” signal on the HS CAN bus is set by another HS CAN bus
subscriber.
