data sheet 2 rev. 1.0 2017-08-09 hs can transceiver high speed can transceiver overview description the tle9250 is the latest infineon hi gh-speed can transceiver generation , used inside hs can networks for automotive and also for industrial a pplications. it is designed to fulf ill the requirements of iso 11898-2 (2016) physical layer specification and respecti vely also the sae standards j1939 and j2284. the tle9250 is available in a pg-dso -8 package and in a small, leadle ss pg-tson-8 packag e. both packages are rohs compliant and halogen fr ee. additionally the pg-tson-8 pa ckage supports the solder joint requirements for automated optical inspection (aoi). as an interface between the physical bus layer and the hs can protocol controller, the tle9250 protects the microcontroller against interferences generated inside the network. a very high esd robustness and the perfect rf immunity allows the use in automotive application without addi ng additional protection devices, like suppressor diodes for example. while the transceiver tle9250 is not s upplied the bus is switched off and illustrate an ideal passive behavior with the lowest possible load to all other subscribers of the hs can network. based on the high symmetry of the canh and canl out put signals, the tle9250 prov ides a very low level of electromagnetic emission (eme) with in a wide frequency range. the tl e9250 fulfills even stringent emc test limits without additional ex ternal circuit, like a common mode choke for example. the perfect transmitter symmetry comb ined with the optimized delay symm etry of the receiver enables the tle9250 to support can fd data frames. depending on the size of the netw ork and the along coming parasitic effects the device supports bit rates up to 5 mbit/s. fail-safe features like overtemperat ure protection, output current limita tion or the txd time-out feature protect the tle9250 and the external circuitry from irreparable damage. type

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 specification of a can bus system includes all electrical specifications of a can network. the can transceiver is part of the physical layer specificatio n. several different physical layer standards of can networks have been developed in recent years. the tl e9250 is a high-speed can transceiver with a dedicated bus wake-up function as de fined in the latest iso

high speed can transceiver high-speed can functional description the tle9250 is a high-speed can transceiver, operating as an interface between th e can controller and the physical bus medium. a hs can network is a two wire, differential network which allows data transmission rates up to 5 mbit/s. the characteristic for a hs ca n 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 bu s and both pins operate as an input and output. the rxd and txd pins are the interface to the microcontroller. the pin txd is the serial data input from the can controller, the rxd pin is the serial data output to the can cont roller. as shown in figure 1 , the hs can transceiver tle9250 includes a re ceiver and a transmitter unit, allowing th e transceiver to send data to the bus medium and monitor the data from the bus medium at the same time. the hs can transceiver tle9250 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 tle9250 monitors the data on the can bus and conv erts 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 th e can bus, followed by a logical ?low? signal on the rxd pin (see figure 3 ). the feature, broadcasting da ta to the can bus and listenin g 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 transc eivers are defined in iso 11898-2. whether a data bit is ?dominant? or ?recessive? depends on the voltage differ ence between the canh and canl pins: v diff = v canh - v canl . to transmit a ?dominant? signal to the can b us the amplitude of the differential signal v diff is higher than or equal to 1.5 v. to receive a ?rec essive? signal from the can bus the amplitude of the differential v diff is lower than or equal to 0.5 v. ?partially-supplied? high-speed can networks are th ose 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 powe r supply and in power-down state. regardless of whether the can bus subscriber is supplied or not, each subscriber co nnected to the common bus media must not interfere with the communication. the tle9250 is designed to support ?partially-supplied? networ ks. in power-down state, the receiver input resistors are switched off an d the transceiver input has a high resistance. for permanently supplied ecu's, the hs can transceiver tle9250 provides a power-save mode. in power-save mode, the power consumption of the tle9250 is optimized to a minimum. the voltage level on the digital input txd and the digita l output rxd is determined by the power supply level at the v cc pin. depending on the voltage level at the v cc pin, the signal levels on the logic pins (stb, txd and rxd) are compatible with microcon trollers having a 5 v i/o supply. data sheet 8 rev. 1.0 2017-08-09 hs can transceiver high speed can transceiver modes of operation 5 modes of operation the tle9250 supports three diff erent modes of operation (see figure 4 and table 2 ): ?

the transmitter is active and drives the serial data stream on the txd input pin to the bus pins canh and canl. ? the normal-mode receiver is active and converts the signals from the bus to a serial data stream on the rxd output. ? the rxd output pin indicates the data received by the normal-mode receiver. ? the bus biasing is connected to v cc /2. ? the nen and nrm input pin is active and changes the mode of operation. ? the txd time-out function is enabled and disconnect s the transmitter in case a time-out is detected. ? the overtemperature protection is enabled and discon nects the transmitter in ca se an overtemperature is detected. ? the undervoltage detection on v cc is enabled and powers down the device in case of detection . normal-operating mode is entered from power-save mo de and receive-only mode, when the nen input pin is set to logical ?low? and nrm input pin is set to logical ?low?. normal-operating mode can only be en tered when all supplies are available: ? the transmitter supply v cc is available ( v cc > v cc(uv,r) ). 5.2 receive-only mode in receive-only mode the transmitte r is disabled and the re ceiver is enabled. the tle9250 can receive data from the bus, but cannot send any message (see also figure 4 and table 2 ): ? the transmitter is disabled and the data available on the txd input is blocked. ?the normal-mode re ceiver is enabled. ? the rxd output pin indicates the data received by the normal-mode receiver. ? the bus biasing is connected to v cc /2. ? the nen and nrm input pins are active and change th e mode of operation to normal-operating mode or power-save mode. ? the txd time-out function is disabled. ? the overtemperature protection is disabled. ? the undervoltage detection on v cc is active and powers down the device in case of detection. ? receive-only mode can only be entered when v cc ( v cc > v cc(uv,r) ) is available. 5.3 power-save mode in power-save mode the transmitter an d receiver are disabled. (see also figure 4 and table 2 ): ? the transmitter is disabled and the data available on the txd input is blocked. ? the receiver is disabled and the da ta available on the bus is blocked. ? the rxd output pin is perman ently set to logical ?high?. ? the bus biasing is floating. ? the nen and nrm input pins are active and change th e mode of operation to normal-operating mode or receive-only mode. ? the overtemperature protection is disabled. data sheet 10 rev. 1.0 2017-08-09 hs can transceiver high speed can transceiver modes of operation ? the undervoltage detection on v cc is enabled and powers down the device in case of detection. 5.4 power-down state independent nrm and nen inpu t pins the tle9250 is powered down if the s upply voltage v cc < (see figure 4 ). in the power-down state the differential input resistor s of the receiver are switch ed off. the canh and canl bus interface of the tle9250 is floating and acts as a high-impedance input with a very small leakage current. the high-ohmic input does not influe nce the ?recessive? level of the ca n network and allows an optimized eme performance of the entire hs can network. in power-down state the tr ansceiver is an invisible node to the bus. data sheet 11 rev. 1.0 2017-08-09 hs can transceiver high speed can transceiver changing the mode of operation 6 changing the mode of operation 6.1 power-up and power-down the hs can transceiver tle9250 powers up by applying the supply voltage v cc to the device ( v cc > v cc(u,r) ). . after powering up, the device enters one out of three operating modes (see figure 5 and figure 6 ). depending on the condition of the mode selection pin nen and nrm the device can enter every mode of operation after the power-up: ? the nen input is set to ?l ow? and nrm input is set to ?high? - normal-operating mode ? the nen input is set to ?high? - power-save mode ? the nen input is set to ?low? and nrm input is set to ?low? - receive-only mode the device tle9250 powers down when the v cc supply falls below the undervoltage detection threshold ( v cc < v cc(u,f) ). the power-down detection is active in every mode of operation. figure 5 power-up and power-down nen nrm v cc power-down state x x off normal-operating mode nen nrm v cc 0 1 on receive-only mode nen nrm v cc 0 0 on power-save mode nen nrm v cc 1 x on v cc on nrm 0 nen 0 v cc on nrm 1 nen 0 v cc on nen 1 v cc off v cc off v cc off v cc off blue -> indicates the event triggering the power-up or power-down red -> indicates the condition which is required to reach a certain operating mode data sheet 12 rev. 1.0 2017-08-09 hs can transceiver high speed can transceiver changing the mode of operation figure 6 power-up an d power-down timings power-down state t pon ) any mode of operation v cc hysteresis v cc(uv,h) t power-save mode t nen x = dont care high due the internal pull-up resistor 1) v cc undervoltage monitor v cc(uv,f) v cc undervoltage monitor v cc(uv,r) t nrm x = dont care high due the internal pull-up resistor 1) 1) assuming no external signal applied t poff "0" for normal-operating mode "1" for power-save mode "1" for normal-operating mode "0" for receive-only mode data sheet 13 rev. 1.0 2017-08-09 hs can transceiver high speed can transceiver changing the mode of operation 6.2 mode change by the nen and nrm pins when the tle9250 is supplied with the digital voltage v cc the internal logic works and mode change by the mode selection pins nen and nrm is possible. by default the nrm input pin and the nen input pin are logical ?high? due to the internal pu ll-up current source to v cc . changing the nen input pin to logica l ?low? in power-save mode triggers a mode change to normal-operating mode (see figure 7 ). to enter normal-operating mode the nrm input pin has to be logical ?high? and the transmitter supply v cc needs to be available. receive-only mode can be entered from normal-opera ting mode and power-save mode by setting the nrm pin to logical ?low?. to enter receive-only mode the nen input pin and the nrm input pin has to be logical ?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 tle9250 disables the transmitter (see figure 8 ). the receiver is still ac tive 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 an d activated again. a permanent ?low? signal on the txd input pin activates the txd time-out function and de activates the transmitter. to release the transmitter after a txd time-out event, the tle 9250 requires a signal change on the txd input pin from logical ?low?
