The IFX1051 is a transceiver designed for HS CAN networks in industrial applications. Acting as interface between
the physical bus layer and the CAN protocol controller, the IFX1051 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 IFX1051 provides a very low level of electromagnetic emission (EME) within a wide frequency
range.
The IFX1051 is available in a small, leadless PG-TSON-8 package. The package is RoHS compliant and halogen
free and moreover supports the solder joint requirements for automated optical inspection (AOI). The IFX1051LE
is fulfilling or exceeding the requirements of the ISO11898-2.
The IFX1051 provides a digital supply input VIO and a receive-only 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 IFX1051 provides an excellent passive
behavior in power-down state. These and other features make the IFX1051 exceptionally suitable for mixed supply
HS CAN networks.
The IFX1051 provides excellent ESD immunity together with a very high electromagnetic immunity (EMI).
Two different operating modes, additional fail-safe features like a TxD time-out and the optimized output slew rates

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) 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 IFX1051 is a High Speed CAN transceiver without a wakeup function and defined by the international standard ISO 11898-2.

The IFX1051 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 bus network which allows data transmission
rates for CAN FD frames up to 2 MBit/s. Main characteristics 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 IFX1051. 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 RM 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 IFX1051 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 RM) and also the RxD output voltage are adapted to the digital power
supply VIO.

Normal-operating Mode
In normal-operating mode the transmitter and the receiver of the HS CAN transceiver IFX1051 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 RM pin selects the normaloperating mode, while the transceiver is supplied by VCC and VIO (see Table 2 for details).

Power-up and Undervoltage Condition
By detecting an undervoltage event, either on the transmitter supply VCC or the digital supply VIO, the transceiver
IFX1051 changes the mode of operation. When the digital power supply VIO is switched off, the transceiver powers
down and remains in the power-down state. When switching off the transmitter supply VCC, the transceiver
changes to the forced power-save mode, (details see Figure 5).

4.3.1
Functional Description
Power-down State
Independent of the transmitter supply VCC and of the RM input pin, the IFX1051 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 IFX1051 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).
Forced Power-save Mode
ge
4.3.2
The forced power-save mode is a fail-safe mode to avoid any disturbance on the HS CAN bus, while the IFX1051
faces a loss of the transmitter supply VCC.
an
In forced power-save mode, the transmitter and the normal-mode receiver are turned off and therefore the
transceiver IFX1051 can not disturb the bus media.
Ch
The RxD output pin is permanently set to logical “high”. The bus biasing is floating (details see Table 2).
4.3.3
- S
ub
je
ct
to
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 or in
receive-only mode (see Figure 5). While the transceiver IFX1051 is in forced power-save mode the RM pin is
disabled.
Power-up
The HS CAN transceiver IFX1051 powers up if at least the digital supply VIO is connected to the device. By default
the device powers up in normal-operating mode, due to the internal pull-down resistor on the RM pin to GND.
In case the device needs to power-up in receive-only mode, the RM pin needs to be pulled active to logical “high”
and the supplies VIO and VCC have to be connected.

By supplying only the digital power supply VIO the IFX1051 powers up in forced power-save mode (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(U,F), the transceiver IFX1051 powers down and
changes to the power-down state.
The undervoltage detection on the digital supply VIO has the highest priority and 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 IFX1051.

and CANL signals correctly to the bus, nor can it receive them properly. Therefore the IFX1051 blocks the
transmitter and the receiver in forced power-save mode (see Figure 7).

The undervoltage detection on the transmitter supply VCC is active in normal-operating mode and in receive-only
mode (see Figure 5).

The HS CAN transceiver IFX1051 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 of the internal logic.
el
To adjust the digital input and output levels of the IFX1051 to the I/O levels of the external microcontroller, connect
the power supply VIO to the microcontroller I/O supply voltage (see Figure 13).
Pr
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.
Unconnected Logic Pins
ge
5.2
5.3
Ch
an
All logic input pins have an internal pull-up resistor to VIO or a pull-down resistor to GND. In case the VIO supply is
activated and the logical pins are open, the IFX1051 enters into the normal-operating mode by default. The TxD
input is pulled to logical “high” due to the internal pull-up resistor to VIO. The HS CAN transceiver IFX1051 will not
influence the data on the CAN bus as long the TxD input pin remains logical “high”.
TxD Time-out Function
- S
ub
je
ct
to
The TxD time-out feature protects the CAN bus against being permanently blocked in case the logical signal at
the TxD pin is continuously “low”. A continuous “low” signal at 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 applied to the TxD pin for the time t > tTxD triggers the TxD time-out feature and the IFX1051 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 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 IFX1051 requires a signal change on the TxD input pin from logical “low” to logical “high”.

Overtemperature Protection
The IFX1051 has an integrated overtemperature detection to protect the IFX1051 against thermal overstress of
the transmitter. The overtemperature protection is active in normal-operating mode and disabled in receive-only
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 circuit.

Examples for Mode Changes
Changing the status on the RM 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 RM pin, when the device IFX1051 is fully supplied. Setting the RM 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”.
ge
Analog to that, changing the RM input pin to logical “high” changes the mode of operation to the receive-only mode
independent on the signals at the CANH, CANL and TxD pins.
an
Note: In case the TxD signal is “low” setting the RM 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
IFX1051 enters normal-operating mode and the TxD input is set to logical “low”.

Application Information
Mode Change while the TxD Signal is “low”
an
ge
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 IFX1051 is in receive-only mode the transmitter is turned off. The IFX1051 drives no signal
to the HS CAN bus. The normal-mode receiver is active in receive-only mode and the RxD indicates the
“recessive” signal on the HS CAN bus with a logical “high” output signal.
Changing the RM to logical “low” turns the mode of operation to normal-operating mode, while the TxD input
remains logical “low”. The transmitter remains disabled until the mode change is completed. The normal-mode
receiver remains active also during the mode change. In normal-operating mode the transmitter becomes active
and the logical “low” signal on the TxD input drives a “dominant” signal to the HS CAN bus. The “dominant” bus
signal is indicated on the RxD output by a logical “low” signal.
Changing the RM pin back to logical “high”, disables the transmitter. The normal-mode receiver and the RxD
output remain active and the “recessive” bus signal is indicated on the RxD output by a logical “high” signal.
Ch
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”
an
ge
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 IFX1051 is in receive-only mode the transmitter is turned off. The IFX1051 drives no signal
to the HS CAN bus. The normal-mode receiver is active in receive-only mode and the RxD indicates the
“dominant” signal on the HS CAN bus with a logical “low” output signal.
Changing the RM to logical “low” turns the mode of operation to normal-operating mode, while the TxD input
remains logical “high”. The transmitter remains disabled until the mode change is completed. The normal-mode
receiver remains active also during the mode change. In normal-operating mode the transmitter becomes active,
the bus remains “dominant” since the bus signal is driven from another HS CAN bus subscriber. The “dominant”
bus signal is indicated on the RxD output by a logical “low” signal.
Regardless which mode of operation is selected by the RM input pin, the RxD output indicates the signal on the
HS CAN bus. Also during the mode transition from receive-only mode to normal-operating mode or vice versa.

Note: The “dominant” signal on the HS CAN bus is set by another HS CAN bus
subscriber.
