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 Sm art 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, additi onal fail-safe features like a Tx D time-out and the optimized output slew rates on the CANH and CANL si gnals, make the TLE8250VSJ the idea l choice for larg e HS CAN networks with high data transmission rates.

4 Functional Description

HS CAN is a serial bus system that connects microcon trollers, 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 spec ification of a CAN bus system incl udes all electrical and mechanical specifications of a CAN network. Th e CAN transceiver is part of the ph ysical layer specif ication. 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 11898-

Data Sheet 7 Rev. 1.0 2016-07-15 TLE8250V High Speed CAN Transceiver Functional Description The TLE8250VSJ is a High-Speed CAN transceiver, operat ing 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 fo r the TLE8250VSJ. The pins CANH an d 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 inpu t 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 transmitte r 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 recessiv e signal sets the RxD output to lo gical “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.

Data Sheet 8 Rev. 1.0 2016-07-15 TLE8250V High Speed CAN Transceiver Functional Description

4.2 Modes of Operation

The TLE8250VSJ supports two differen t modes of operation, power-save mode and normal-operating mode while the transceiver is s upplied according to the sp ecified functional range. The mode of operation is selected by the NEN input pin (see Figure 4). Figure 4 Mode state diagram

4.2.1 Normal-operating Mode

In normal-operating mode the transmitter and the re ceiver of the HS CAN transceiver TLE8250VSJ are active (see Figure 1). The HS CAN transceiver sends th e serial data stream on the TxD input pin to the CAN bus. The data on the CAN bus is displayed at the RxD pin simult aneously. 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 pi n 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 V CC is turned off, allowing to switch off the VCC supply in power-save mode. VCC > VCC(UV,R) NEN = 0 normal-operating mode NEN = 1 power-save mode NEN = 0 NEN = 1 VIO > VIO(UV,R) VCC = “don’t care” VIO > VIO(UV,R)

Data Sheet 9 Rev. 1.0 2016-07-15 TLE8250V High Speed CAN Transceiver Functional Description

4.3 Power-up and Unde rvoltage Condition

By detecting an undervoltage event, either on the transmitter supply VCC or the digital supply VIO, the transceiver TLE8250VSJ ch anges the mode of operation. Turn ing off the digita l 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 th e forced power-save mode, or remain s in power-save mode (details see Figure 5).

Data Sheet 10 Rev. 1.0 2016-07-15 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 TL E8250VSJ 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 th e receiver are disconnected from the bus biasing VCC/2. The CANH and CANL bus interface of the TLE8250VSJ is floa ting and acts as a high-i mpedance 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 tran smitter 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 V CC is not available, either by powering up the digital supply VIO only or by turning off the transmi tter supply in normal-operating mode. While the transceiver TLE8250VSJ is in forced power- save mode, switching the NE N 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 NE N 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 eith er in forced power-save mode or in power-save mode, depending on the signal of the NEN input pin (see Figure 5).

Data Sheet 11 Rev. 1.0 2016-07-15 TLE8250V High Speed CAN Transceiver Functional Description

4.3.4 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. Figure 6 Undervoltage on the digital supply VIO

4.3.5 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 re ceive them properly. Therefore the TLE8250VSJ blocks the transmitter and the receiver in forced power-save mode (see Figure 7).

4.3.6 Voltage Adaption to the Microcontroller Supply

The HS CAN transceiver TLE8250VSJ ha s 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: In case the digital supply voltage V IO is not required in the application, connect the digital supply voltage VIO to the transmitter supply VCC. forced stand-by mode digital supply voltage VIO = “on” tDelay(UV) delay time undervoltage normal-operating mode VCC hysteresis VCC(UV,H) t normal-operating mode t NEN Assuming the NEN remains “low”.

Data Sheet 13 Rev. 1.0 2016-07-15 TLE8250V High Speed CAN Transceiver Fail Safe Functions

5 Fail Safe Functions

5.1 Short Circuit Protection

The CANH and CANL bus outputs are sh ort circuit proof, either against GN D or a positive supply voltage. A current limiting circuit pr otects the transceiver against damages. If the device is heating up due to a continuous short on the CANH or CANL, the internal over temperature 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 th e 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 > t TxD 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”.

Data Sheet 14 Rev. 1.0 2016-07-15 TLE8250V High Speed CAN Transceiver Fail Safe Functions

5.4 Overtemperature Protection

The TLE8250VSJ has an integrated overtemperature detection to protect the TLE8250VSJ against thermal overstress of the transmitter. The overtemperature protection is acti ve in normal-operating mode and disabled in power-save mode. In case of an overtemp erature condition, the temper ature 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. Figure 9 Overtemperature protection

5.5 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).

8.3 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-ope rating mode. The TxD time-out timer starts when the TLE8250VSJ enters normal-operating mode and the TxD input is set to logical “low”.

Data Sheet 28 Rev. 1.0 2016-07-15 TLE8250V High Speed CAN Transceiver

8.3.1 Mode Change while th e TxD Signal is “low”

The example in Figure 14 shows a mode change to normal-operati ng 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 transmitte r 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 an d 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 Tx D 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.

Data Sheet 29 Rev. 1.0 2016-07-15 TLE8250V High Speed CAN Transceiver

8.3.2 Mode Change while th e Bus Signal is dominant

The example in Figure 15 shows a mode change while the bus is do minant and the TxD input signal is set to logical “high”. While the transceiver TLE8250VSJ is in power-save mode, the transmitte r 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 transmi tter 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.
