As an interface between the physical bus layer and the CAN protocol controller, the TLE7250G 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 TLE7250G provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE7250G is integrated in a RoHS compliant PG-DSO-8 package and fulfills or exceeds the requirements of ISO 11898-2. As a successor to the first generation of HS CAN transceivers, the pin assignment and function of the TLE7250G is fully compatible with its predecessor model, the TLE6250G. The TLE7250G is optimized to provide an excellent passive behavior in the power-down state. This feature makes the TLE7250G extremely suitable for mixed supply CAN networks. Based on the Infineon Smart Power Technology SPT, the TLE7250G provides excellent ESD immunity together with a very high electromagnetic immunity (EMI). The Infineon Smart Power Technology SPT allows bipolar and CMOS control circuitry in accordance with DMOS power devices to exist on the same monolithic circuit. The TLE7250G 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 TxD time-out and the optimized output slew rates on the CANH and CANL signals make the TLE7250G the ideal choice for large CAN networks with high data transmission rates.

Data Sheet 5 Rev. 1.1, 2013-07-22 TLE7250G Functional Description 4 Functional Description CAN is a serial bus system that connects microcontrollers, sensors and actuators for real-time control applications. The use of the Control 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 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 definitions of CAN networks have been developed in recent years. The TLE7250G is a High Speed CAN transceiver without a dedicated wake-up function. High Speed CAN transceivers without a wake-up function are defined by the international standard ISO 11898-2. 4.1 High Speed CAN Physical Layer TxD VCC t CAN_H CAN_L VCC VCC = TxD = RxD = CANH = CANL = VDIFF = High Speed CAN power supply Input from the microcontroller Output to the microcontroller Voltage on the CANH input/output Voltage on the CANL input/output Differential voltage between CANH and CANL VDIFF = VCANH – VCANL t VDIFF “dominant“ VDIFF = ISO level “dominant“ VDIFF = ISO level “recessive“ “recessive“ t RxD VCC t Figure 3 Data Sheet High Speed CAN bus signals and logic signals 6 Rev. 1.1, 2013-07-22 TLE7250G Functional Description The TLE7250G is a High Speed CAN transceiver, operating as an interface between the CAN controller and the physical bus medium. An HS CAN network is a two-wire, differential network, which allows data transmission rates up to 1 Mbps. The characteristics of an HS CAN network are the two signal states on the CAN bus: “dominant” and “recessive” (see Figure 3). The CANH and CANL pins are the interface to the CAN bus and both pins operate as an input and output. The RxD and TxD pins are the interface to the microcontroller. The TxD pin is the serial data input from the CAN controller, and the RxD pin is the serial data output to the CAN controller. As shown in Figure 1, the HS CAN transceiver TLE7250G includes a receiver and a transmitter unit, allowing the transceiver to send data to the bus medium and monitor the data from the bus medium at the same time. The HS CAN transceiver TLE7250G converts the serial data stream which is available on the transmit data input TxD, into a differential output signal on the CAN bus, provided by the CANH and CANL pins. The receiver stage of the TLE7250G monitors the data on the CAN bus and converts them to a serial, single-ended signal on the RxD output pin. A logical “low” signal on the TxD pin creates a “dominant” signal on the CAN bus, followed by a logical “low” signal on the RxD pin (see Figure 3). The feature of broadcasting data to the CAN bus and listening to the data traffic on the CAN bus simultaneously is essential to support the bit-to-bit arbitration within CAN networks. The voltage levels for HS CAN transceivers are defined by the ISO 11898-2 and the ISO 11898-5 standards. Whether a data bit is “dominant” or “recessive” depends on the voltage difference between the CANH and CANL pins: VDIFF = VCANH - VCANL. In comparison with other differential network protocols, the differential signal on a CAN network can only be larger than or equal to 0 V. To transmit a “dominant” signal to the CAN bus, the differential signal VDIFF is larger than or equal to 1.5 V. To receive a “recessive” signal from the CAN bus, the differential VDIFF is smaller than or equal to 0.5 V. “Partially-supplied” High Speed CAN networks are those where the CAN bus nodes of one common network have different power supply conditions. Some nodes are connected to the common power supply, while other nodes are disconnected from the power supply and in power-down state. Regardless of whether the CAN bus subscriber is supplied or not, each subscriber connected to the common bus media must not interfere with the communication. The TLE7250G is designed to support “partially-supplied” networks. In power-down state, the receiver input resistors are switched off and the transceiver input has a high resistance. Data Sheet 7 Rev. 1.1, 2013-07-22 TLE7250G Functional Description 4.2 Modes of Operation Three different modes of operation are available on the TLE7250G. Each mode has specific characteristics in terms of quiescent current or data transmission. NEN and NRM are used as the digital input pins for mode selection. Figure 4 illustrates the different mode changes depending on the status of the NEN and NRM pins. After supplying VCC to the HS CAN transceiver, the TLE7250G starts in stand-by mode. The internal pull-up resistors set the TLE7250G to stand-by mode by default. If the microcontroller is up and running, the TLE7250G can switch to any mode of operation within the time period for mode change tMode. undervoltage detection on VCC start–up supply VCC VCC < VCC(UV) power-down stand-by mode NRM = 1 NEN = 0 NEN = 1 NRM = 0/1 NEN = 1 Figure 4 NRM = 0/1 NEN = 1 NRM = 0 NEN = 0 normal-operating mode NEN = 0 NRM = 0 NEN = 0 NRM = 0/1 receive-only mode NRM = 1 NRM = 1 NEN = 0 NEN = 0 NRM = 0 Modes of operation The TLE7250G has 3 major modes of operation: • • • Stand-by mode Normal-operating mode Receive-only mode Table 2 Modes of Operation Mode NRM NEN Bus Bias Comments Normal-operating “high” mode “low” VCC/2 The transmitter is active. The receiver is active. Stand-by “low” or “high” “high” GND The transmitter is disabled. The receiver is disabled. Receive-only “low” “low” VCC/2 The transmitter is disabled. The receiver is active. VCC off “low” or “high” “low” or “high” floating The transmitter is disabled. The receiver is disabled. Data Sheet 8 Rev. 1.1, 2013-07-22 TLE7250G Functional Description 4.3 Normal-operating Mode In the normal-operating mode, the HS CAN transceiver TLE7250G sends the serial data stream on the TxD pin to the CAN bus. The data on the CAN bus is displayed at the RxD pin simultaneously. In the normal-operating mode, all functions of the TLE7250G are active: • • • • The transmitter is active and drives data from the TxD to the CAN bus. The receiver is active and provides the data from the CAN bus to the RxD pin. The bus biasing is set to VCC/2. The undervoltage monitoring at the power supply VCC is active. To enter the normal-operating mode, set the pin NRM to logical “high” and the pin NEN to logical “low” (see Table 2 or Figure 4). Both pins, the NEN pin and the NRM pin have internal pull-up resistors to the power-supply VCC. 4.4 Receive-only Mode The receive-only mode can be used to test the connection of the bus medium. The TLE7250G can still receive data form the bus, but the transmitter is disabled and hence, no data can be sent to the CAN bus. All other functions are active: • • • • The transmitter is disabled and data, which is available on the TxD pin, is blocked and not sent to the CAN bus. The receiver is active and provides the data from the CAN bus to the RxD output pin. The bus biasing is set to VCC/2. The undervoltage monitoring on the power supply VCC is active. To enter the receive-only mode, set the pin NRM to logical “low” and the pin NEN to logical “low” (see Table 2 or Figure 4). In case the receive-only mode is not used, the NRM pin can be left open. 4.5 Stand-by Mode The stand-by mode is an idle mode of the TLE7250G with optimized power consumption. In the stand-by mode, the TLE7250G can not send or receive any data. The transmitter and the receiver are disabled. Both CAN bus pins, CANH and CANL are connected to GND via the input resistors. • • • • The transmitter is disabled. The receiver is disabled. The input resistors of the receiver unit are connected to GND. The undervoltage monitoring at the power supply VCC is active. To enter the stand-by mode, set the pin NEN to logical “high”, the logical state of the NRM pin has no influence on the mode selection (see Table 2 or Figure 4). Both pins, the NEN and the NRM pin have an internal pull-up resistor to the power-supply VCC. If the stand-by mode is not used in the application, the NEN pin needs to be connected to GND. In case the NRM pin is set to logical “low” in the stand-by mode, the internal pull-up resistor causes an additional quiescent current from VCC to GND, therefore it is recommended to set the NRM pin to logical “high” in stand-by mode or leave the pin open, if the receive-only mode is not used in the application. 4.6 Power-down state The power-down state means that the TLE7250G is not supplied. In power-down state, the differential input resistors of the receiver stage are switched off. The CANH and CANL bus interface of the TLE7250G acts as highimpedance 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 CAN network. Data Sheet 9 Rev. 1.1, 2013-07-22 TLE7250G 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 damage. If the device heats up due to a continuous short on the CANH or CANL, the internal overtemperature protection switches off the 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 or floating, the TLE7250G enters into the stand-by mode by default. In stand-by mode, the transmitter of the TLE7250G is disabled, the bus bias is connected to GND and the HS CAN TLE7250G transceiver does not influence the data on the CAN bus. 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 can have its root cause in a locked-up microcontroller or in a short 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 and the TLE7250G disables the transmitter (see Figure 5). 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 5 TxD Time-out function Figure 5 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 TLE7250G requires a signal change on the TxD input pin from logical “low” to logical “high”. 5.4 Undervoltage Detection The HS CAN Transceiver TLE7250G is provided with undervoltage detection at the power supply VCC. In case of an undervoltage event on VCC, the undervoltage detection changes the operating mode of TLE7250G to the standby mode, regardless of the logical signal on the NEN and NRM pins (see Figure 6). If the transceiver TLE7250G recovers from the undervoltage condition, the operating mode is restored to the programmed mode by the logical pins NEN and NRM.

In this case NEN remains “low“ and NRM remains “high“.

In case of an overtemperature condition, the temperature sensor will disable the transmitter (see Figure 1). After the device cools down, the transmitter is activated again (see Figure 7). A hysteresis is implemented within the temperature sensor.
