Description
The TLE7250V is a transceiver designed for HS CAN networks in automotive and industrial applications. As an
interface between the physical bus layer and the CAN protocol controller, the TLE7250V drives the signals to the
bus and protects the microcontroller against interferences generated within the network. Based on the high
symmetry of the CANH and CANL signals, the TLE7250V provides a very low level of electromagnetic emission
(EME) within a wide frequency range.
The TLE7250V is available in a small, leadless PG-TSON-8 package and in a PG-DSO-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). The TLE7250VLE and the TLE7250VSJ are fulfilling or
exceeding the requirements of the ISO11898-2.
The TLE7250V 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 TLE7250V provides an excellent
passive behavior in power-down state. These and other features make the TLE7250V exceptionally suitable for

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 TLE7250V is a High Speed CAN
transceiver without a wake-up function and defined by the international standard ISO 11898-2.

TLE7250VSJ
Functional Description
The TLE7250V 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 TLE7250V. 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 TLE7250V 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 TLE7250V 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
4.2.1
Normal-operating Mode
In normal-operating mode the transmitter and the receiver of the HS CAN transceiver TLE7250V 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 TLE7250V with optimized power consumption. In power-save mode
the transmitter and the normal-mode receiver are turned off. The TLE7250V 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
TLE7250V 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 Figure 5).

Functional Description
4.3.1
Power-down State
Independent of the transmitter supply VCC and of the NEN input pin, the TLE7250V 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 TLE7250V 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
TLE7250V 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 TLE7250V 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 TLE7250V 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 TLE7250V 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 TLE7250V 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
4.3.4
If the voltage on VIO supply input falls below the threshold VIO < VIO(UV,F), the transceiver TLE7250V 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 TLE7250V.

Undervoltage on the Transmitter Supply VCC
In case the transmitter supply VCC falls below the threshold VCC < VCC(UV,F), the transceiver TLE7250V changes
the mode of operation to forced power-save mode. The transmitter and also the normal-mode receiver of the
TLE7250V are powered by the VCC supply. In case of an insufficient VCC supply, the TLE7250V can neither
transmit the CANH and CANL signals correctly to the bus, nor can it receive them properly. Therefore the
TLE7250V 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).

The HS CAN transceiver TLE7250V 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 TLE7250V 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: 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 TLE7250V enters into the power-save mode by default. In power-save mode the transmitter of the
TLE7250V 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 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 TLE7250V 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.

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 TLE7250V requires a signal change on the TxD input pin from logical “low” to logical “high”.

Overtemperature Protection
The TLE7250V has an integrated overtemperature detection to protect the TLE7250V 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 TLE7250V 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).

Examples for Mode Changes
Changing the status on the NEN input pin triggers a change of the operating mode, disregarding the actual signal
on the CANH, CANL and TxD pins (see also Chapter 4.2).
Mode changes are triggered by the NEN pin, when the device TLE7250V is fully supplied. Setting the NEN pin to
logical “low” changes the mode of operation to normal-operating mode:
•
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
TLE7250V enters normal-operating mode and the TxD input is set to logical “low”.

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 TLE7250V is in power-save mode, the transmitter and the normal-mode receiver are turned
off. The TLE7250V 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 TLE7250V is in power-save mode, the transmitter and the normal-mode receiver are turned
off. The TLE7250V 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 TLE7250V 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.
