As an interface between the physical bus layer and the CAN protocol controller, the TLE7250 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 TLE7250 provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE7250 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 TLE7250LE and the TLE7250SJ are fulfilling or exceeding the requirements of the ISO11898-2. The TLE7250 provides a receive-only mode 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 TLE7250 provides an excellent passive behavior in power-down state. These and other features make the TLE7250 exceptionally suitable for mixed supply HS CAN networks. Based on the Infineon Smart Power Technology SPT, the TLE7250 provides excellent ESD immunity together with Type Package Marking TLE7250LE PG-TSON-8 7250 TLE7250SJ PG-DSO-8 7250 Data Sheet 3 Rev. 1.0, 2015-08-12 TLE7250LE TLE7250SJ Overview a very high electromagnetic immunity (EMI). The TLE7250 and the Infineon SPT technology are AEC qualified and tailored to withstand the harsh conditions of the automotive environment. Three 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 TLE7250 the ideal choice for large HS CAN networks with high data transmission rates.

Data Sheet 7 Rev. 1.0, 2015-08-12 TLE7250LE TLE7250SJ Functional Description 4 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 TLE7250 is a High Speed CAN transceiver without a wake-up function and defined by the international standard ISO11898-2. 4.1 High Speed CAN Physical Layer TxD VCC = TxD = VCC RxD = CANH = t CANH CANL CANL = VDiff = VCC Transmitter supply voltage Transmit data input from the microcontroller Receive data output to the microcontroller Bus level on the CANH input/output Bus level on the CANL input/output Differential voltage between CANH and CANL VDiff = VCANH – VCANL t VDiff VCC “dominant” receiver threshold “recessive” receiver threshold t RxD VCC tLoop(H,L) Figure 3 Data Sheet tLoop(L,H) t High speed CAN bus signals and logic signals 8 Rev. 1.0, 2015-08-12 TLE7250LE TLE7250SJ Functional Description The TLE7250 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 and GND are the supply pins for the TLE7250. 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 and NRM pins are the input pins for the mode selection (see Figure 4). By setting the TxD input pin to logical “low” the transmitter of the TLE7250 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. Data Sheet 9 Rev. 1.0, 2015-08-12 TLE7250LE TLE7250SJ Functional Description 4.2 Modes of Operation The TLE7250 supports three different modes of operation, power-save mode, receive-only mode and normaloperating mode while the transceiver is supplied according to the specified functional range. The mode of operation is selected by the NEN and the NRM input pins (see Figure 4). VCC > VCC(UV,R) power-save mode NEN = 0 NRM = 1 NEN = 1 NEN = 1 NRM = “X” normal-operating mode NEN = 0 NRM = 1 NEN = 0 NRM = 0 NEN = 0 NRM = 0 NEN = 0 NRM = 1 VCC > VCC(UV,R) Figure 4 Mode state diagram 4.2.1 Normal-operating Mode NEN = 1 NRM = “X” NRM = “X” receive-only mode NEN = 0 NRM = 0 VCC > VCC(UV,R) In normal-operating mode the transmitter and the receiver of the HS CAN transceiver TLE7250 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 and a logical “high” signal on the NRM pin selects the normal-operating mode, while the transceiver is supplied by VCC (see Table 2 for details). 4.2.2 Power-save Mode The power-save mode is an idle mode of the TLE7250 with optimized power consumption. In power-save mode the transmitter and the normal-mode receiver are turned off. The TLE7250 can not send any data to the HS CAN bus nor receive any data from the HS 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 transmitter supply VCC (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. 4.2.3 Receive-only Mode In receive-only mode the normal-mode receiver is active and the transmitter is turned off. The TLE7250 can receive data from the HS CAN bus, but cannot send any data to the HS CAN bus. A logical “low” signal on the NEN pin and a logical “low” signal on the NRM pin selects the receive-only mode, while the transceiver is supplied by VCC (see Table 2 for details). Data Sheet 10 Rev. 1.0, 2015-08-12 TLE7250LE TLE7250SJ Functional Description 4.3 Power-up and Undervoltage Condition By detecting an undervoltage event or by switching off the transmitter power supply VCC, the transceiver TLE7250 changes the mode of operation (details see Figure 5). normal-operating mode VCC “on” NEN “0” NRM “1” NEN NRM 0 power-down state NEN NRM “X” “X” VCC NEN NRM Table 2 Modes of operation 0 NEN NRM “X” 0 VCC “on” VCC “on” NEN “1” NRM “X” power-save mode 1 Power-up and undervoltage VCC “on” NEN “0” NRM “0” receive-only mode VCC “on” NEN “1” NRM “X” VCC “on” NEN “0” NRM “X” Figure 5 “on” VCC “on” NEN “0” NRM “1” VCC “on” NEN “0” NRM “0” “off” 1 VCC “on” NEN “0” NRM “1” VCC VCC “on” NEN “0” NRM “0” VCC “on” Mode NEN NRM VCC Bus-bias Transmitter Normal-mode Low-power Receiver Receiver Normal-operating “low” “high” “on” VCC/2 “on” “on” not available Power-save “high” “X” “on” floating “off” “off” not available Receive-only “low” Power-down state “X” Data Sheet “low” “on” VCC/2 “off” “on” not available “X” “off” floating “off” “off” not available 11 Rev. 1.0, 2015-08-12 TLE7250LE TLE7250SJ Functional Description 4.3.1 Power-down State Independent of the NEN and NRM input pins the TLE7250 is in power-down state when the transmitter supply voltage VCC 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 TLE7250 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 Power-up The HS CAN transceiver TLE7250 powers up if the transmitter supply VCC 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 VCC. In case the device needs to power-up to normal-operating mode, the NEN pin needs to be pulled active to logical “low” while the NRM pin is logical “high” (see Figure 5). Data Sheet 12 Rev. 1.0, 2015-08-12 TLE7250LE TLE7250SJ Functional Description Undervoltage on the Transmitter Supply VCC 4.3.3 In case the transmitter supply VCC falls below the threshold VCC < VCC(UV,F), the transceiver TLE7250 can not provide the correct bus levels to the CANH and CANL anymore. The normal-mode receiver is powered by the transmitter supply VCC. In case of insufficient VCC supply the TLE7250 can neither transmit the CANH and CANL signals correctly to bus nor can it receive them properly. Therefore the TLE7250 powers down and blocks both, the transmitter and the receiver. The transceiver TLE7250 powers up again, when the transmitter supply VCC recovers from the undervoltage condition.

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 VCC. In case the VCC supply is activated and the logical pins are open, the TLE7250 enters into the power-save mode by default. In power-save mode the transmitter of the TLE7250 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 TLE7250 disables the transmitter (see Figure 7). The receiver is still active and the data on the bus continues to be monitored by the RxD output pin. t > tTxD TxD time-out CANH CANL TxD time–out released t TxD t RxD t Figure 7 TxD time-out function Figure 7 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 TLE7250 requires a signal change on the TxD input pin from logical “low” to logical “high”. Data Sheet 14 Rev. 1.0, 2015-08-12 TLE7250LE TLE7250SJ Fail Safe Functions 5.4 Overtemperature Protection The TLE7250 has an integrated overtemperature detection to protect the TLE7250 against thermal overstress of the transmitter. The overtemperature protection is active in normal-operating mode and disabled in power-save mode and 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 8). A hysteresis is implemented within the temperature sensor.

Depending on the selected mode of operation, the RxD output pin is set to logical “high” during the mode change. In this case the RxD output does not reflect the status on the CANH and CANL input pins (see as an example Figure 13 and Figure 14).

Mode changes are triggered by the NRM pin and NEN pin, when the device TLE7250 is fully supplied. Setting the NEN pin to logical “low” and the NRM pin to logical “high” 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. Changing the NEN input pin and the NRM input pin to logical “low” changes the mode of operation to the receive-only mode. Both mode changes are independent on the signals at the CANH, CANL and TxD pins. Note: In case the TxD signal is “low” setting the NRM input pin to logical “high” and the NEN input pin to logical “low” changes 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 TLE7250 enters normal-operating mode and the TxD input is set to logical “low”. Data Sheet 27 Rev. 1.0, 2015-08-12 TLE7250LE TLE7250SJ Application Information 8.3.1 Mode Change while the TxD Signal is “low” The example in Figure 13 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 TLE7250 is in power-save mode, the transmitter and the normal-mode receiver are turned off. The TLE7250 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 transceiver 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 pin becomes logical “low”, following the “dominant” signal on the HS CAN bus. Changing the mode of operation from normal-operating mode to receive-only mode by setting the NRM input pin to “low”, disables the transmitter and the TxD input, but the normal-mode receiver and the RxD output remain active. The HS CAN bus becomes “recessive” since the transmitter is disabled. The RxD input indicates the “recessive” HS CAN bus signal by a logical “high” output signal (see also the example in Figure 13). Mode changes between the power-save mode on the one side and the normal-operating mode or the receive-only mode on the other side, disable the transmitter and the normal-mode receiver. No signal can be driven to the HS CAN bus nor can it be received from the HS CAN bus. Mode changes between the normal-operating mode and the receive-only mode disable the transmitter and the normal mode receiver remains active. The HS CAN transceiver TLE7250 monitors the HS CAN bus also during the mode transition from normal-operating mode to receive-only mode and vice versa. 8.3.2 Mode Change while the Bus Signal is “dominant” The example in Figure 14 shows a mode change while the bus is “dominant” and the TxD input signal is set to logical “high”. While the transceiver TLE7250 is in power-save mode, the transmitter and the normal-mode receiver are turned off. The TLE7250 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 transceiver and the receiver are active and therefor the RxD output changes to logical “low” indicating the “dominant” signal on the HS CAN bus. Changing the mode of operation from normal-operating mode to receive-only mode by setting the NRM input pin to “low”, disables the transmitter and the TxD input, but the normal-mode receiver and the RxD output remain active. Since the “dominant” signal on the HS CAN bus is driven by another HS CAN bus subscriber, the bus remains “dominant” and the RxD input indicates the “dominant” HS CAN bus signal by a logical “low” output signal (see also the example in Figure 14).
