As an interface between the physical bus layer and the CAN protocol controller, the TLE7250X 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 TLE7250X provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE7250X 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 TLE7250XLE and the TLE7250XSJ are fulfilling or exceeding the requirements of the ISO11898-2. The TLE7250X 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 TLE7250X provides an excellent passive behavior in power-down state. These and other features make the TLE7250X exceptionally suitable for mixed supply HS CAN networks.

The TLE7250X 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 TLE7250X the ideal choice for large HS CAN networks with high data transmission rates.

Data Sheet 7 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ 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 TLE7250X is a High Speed CAN transceiver without a wake-up function and defined by the international standard ISO 11898-2. 4.1 High Speed CAN Physical Layer VIO = VCC = TxD = TxD VIO RxD = CANH = t CANH CANL CANL = VDiff = VCC Digital supply voltage 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 VIO 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 TLE7250XLE TLE7250XSJ Functional Description The TLE7250X 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 TLE7250X. 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 TLE7250X 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. Data Sheet 9 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Functional Description 4.2 Modes of Operation The TLE7250X supports two different modes of operation, receive-only mode and normal-operating mode while the transceiver is supplied according to the specified functional range. The mode of operation is selected by the RM input pin (see Figure 4). receive-only mode VCC > VCC(UV) VIO > VIO(UV,R) RM = 1 RM = 0 VCC > VCC(UV,R) RM = 1 normal-operating mode VIO > VIO(UV,R) RM = 0 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 TLE7250X 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). 4.2.2 Receive-only Mode In receive-only mode the normal-mode receiver is active and the transmitter is turned off. The TLE7250X can receive data from the HS CAN bus, but cannot send any data to the HS CAN bus. A logical "high" signal on the RM pin selects the receive-only mode, while the transceiver is supplied by VCC and VIO (see Table 2 for details). Data Sheet 10 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Functional Description 4.3 Power-up and Undervoltage Condition By detecting an undervoltage event, either on the transmitter supply VCC or the digital supply VIO, the transceiver TLE7250X 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 changes to the forced power-save mode, (details see Figure 5). normal-operating mode VIO "on" VCC "on" RM "0" power-down state RM VCC VIO "X" "X" "off" RM VCC VIO 0 "on" "on" VIO "on" VCC "on" RM "0" VIO "on" VCC "off" RM "X" VIO "on" VCC "on" RM "1" receive-only mode VIO "on" VCC "on" RM "1" Figure 5 Power-up and undervoltage Table 2 Modes of operation RM VCC VIO 1 "on" "on" VIO "on" VCC "on" RM "0" VIO "on" VCC "off" RM "0" forced power-save mode RM VCC VIO "X" "off" "on" VIO "on" VCC "on" RM "1" VIO "on" VCC "off" RM "1" Mode RM VIO VCC Bus Bias Transmitter Normal-mode Low-power Receiver Receiver Normal-operating "low" "on" "on" "on" "on" not available Receive-only "high" "on" "on" VCC/2 VCC/2 "off" "on" not available Forced power-save "X" "on" "off" floating "off" "off" not available Power-down state "off" "X" floating "off" "off" not available Data Sheet "X" 11 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Functional Description 4.3.1 Power-down State Independent of the transmitter supply VCC and of the RM input pin, the TLE7250X 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 TLE7250X 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 TLE7250X 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 TLE7250X 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 or in receive-only mode (see Figure 5). While the transceiver TLE7250X is in forced power-save mode the RM pin is disabled. 4.3.3 Power-up The HS CAN transceiver TLE7250X 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 TLE7250X powers up in forced power-save mode (see Figure 5). Data Sheet 12 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Functional Description 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 TLE7250X 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 TLE7250X. transmitter supply voltage VCC = "don't care" VIO VIO undervoltage monitor VIO(UV,R) hysteresis VIO(UV,H) VIO undervoltage monitor VIO(UV,F) tDelay(UV) delay time undervoltage t any mode of operation power-down state RM normal-operating mode "low" due the internal pull-down resistor1) "X" = don't care t 1)assuming Figure 6 Data Sheet no external signal applied Undervoltage on the digital supply VIO 13 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Functional Description Undervoltage on the Transmitter Supply VCC 4.3.5 In case the transmitter supply VCC falls below the threshold VCC < VCC(UV,F), the transceiver TLE7250X changes the mode of operation to forced power-save mode. The transmitter and also the normal-mode receiver of the TLE7250X are powered by the VCC supply. In case of an insufficient VCC supply, the TLE7250X can neither transmit the CANH and CANL signals correctly to the bus, nor can it receive them properly. Therefore the TLE7250X 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). digital supply voltage VIO = "on" VCC VCC undervoltage monitor VCC(UV,R) hysteresis VCC(UV,H) VCC undervoltage monitor VCC(UV,F) tDelay(UV) delay time undervoltage t any mode of operation forced power-save mode RM normal-operating mode "low" due the internal pull-down resistor1) "X" = don't care t 1)assuming no external signal applied Figure 7 Undervoltage on the transmitter supply VCC 4.3.6 Voltage Adaption to the Microcontroller Supply The HS CAN transceiver TLE7250X 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 TLE7250X 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. Data Sheet 14 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Fail Safe Functions 5 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 or a pull-down resistor to GND. In case the VIO supply is activated and the logical pins are open, the TLE7250X 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 TLE7250X will not influence the data on the CAN bus as long the TxD input pin remains logical "high". 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 TLE7250X 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. t > tTxD TxD time-out CANH CANL TxD time-out released t TxD t RxD t 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 TLE7250X requires a signal change on the TxD input pin from logical "low" to logical "high". Data Sheet 15 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Fail Safe Functions 5.4 Overtemperature Protection The TLE7250X has an integrated overtemperature detection to protect the TLE7250X 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.

During the mode change the normal-mode receiver and the RxD output are active and reflect the on the HS CAN input pins (see as an example Figure 14 and Figure 15).

Mode changes are triggered by the RM pin, when the device TLE7250X 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". 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. 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 TLE7250X enters normal-operating mode and the TxD input is set to logical "low". Data Sheet 28 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ 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 TLE7250X is in receive-only mode the transmitter is turned off. The TLE7250X 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. Note: The signals on the HS CAN bus are "recessive", the "dominant" signal is generated by the TxD input signal t = tMode t = tMode RM t TxD t VDIFF t RxD t receive-only transition normal-operating transition receive-only normal-mode receiver and RxD output active TxD input and transmitter blocked Figure 14 Data Sheet TxD input and transmitter active TxD input and transmitter blocked Example for a mode change while the TxD is "low" 29 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Application Information 8.3.2 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 TLE7250X is in receive-only mode the transmitter is turned off. The TLE7250X 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. t = tMode t = tMode RM t TxD t VDIFF t RxD t receive-only mode transition normal-operating transition receive-only mode normal-mode receiver and RxD output active TxD input and transmitter blocked Figure 15 Data Sheet TxD input and transmitter active TxD input and transmitter blocked Example for a mode change while the HS CAN is "dominant" 30 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Application Information 8.4 Further Application Information * Please contact us for information regarding the pin FMEA. * Existing application note. * For further information you may visit: http://www.infineon.com/ Data Sheet 31 Rev. 1.0, 2015-08-12 TLE7250XLE TLE7250XSJ Package Outline 0 +0.05 10.1 Package Outline 0.3 0.1 Pin 1 Marking 1.63 0.1 0.56 0.1 0.25 0.1 3 0.1 0.05 Z 0.38 0.1 0.4 0.1 3 0.1 2.4 0.1 1.58 0.1 0.1 0.1 0.81 0.1 0.2 0.1 9 0.65 0.1 Pin 1 Marking 0.3 0.1 PG-TSON-8-1-PO V01 Z (4:1) 0.07 MIN.
