2 Overview Descripion Type Package Marking LE PG-TSON V SJ PG-DSO V The is he laes Infineon high-speed CAN ransceiver generaion, used inside HS CAN neworks for auomoive and also for indusrial applicaions. I is designed o fulfill he requiremens of ISO (2016) physical layer specificaion and respecively also he SAE sandards J1939 and J2284. The is available in a PG-DSO-8 package and in a small, leadless PG-TSON-8 package. Boh packages are RoHS complian and halogen free. Addiionally he PG-TSON-8 package suppors he solder join requiremens for auomaed opical inspecion (AOI). As an inerface beween he physical bus layer and he HS CAN proocol conroller, he proecs he microconroller agains inerferences generaed inside he nework. A very high ESD robusness and he perfec RF immuniy allows he use in auomoive applicaion wihou adding addiional proecion devices, like suppressor diodes for example. While he ransceiver is no supplied he bus is swiched off and illusrae an ideal passive behavior wih he lowes possible load o all oher subscribers of he HS CAN nework. Based on he high symmery of he CANH and CANL oupu signals, he provides a very low level of elecromagneic emission (EME) wihin a wide frequency range. The fulfills even sringen EMC es limis wihou addiional exernal circui, like a common mode choke for example. The perfec ransmier symmery combined wih he opimized delay symmery of he receiver enables he o suppor CAN FD daa frames. Depending on he size of he nework and he along coming parasiic effecs he device suppors bi raes up o 5 MBi/s. Fail-safe feaures like overemperaure proecion, oupu curren limiaion or he TxD ime-ou feaure proec he and he exernal circuiry from irreparable damage. Daa Shee 2 Rev. 1.1

6 High-speed CAN funcional descripion 4 High-speed CAN funcional descripion HS CAN is a serial bus sysem ha connecs microconrollers, sensors and acuaors for real-ime conrol applicaions. The use of he Conroller Area Nework (abbreviaed CAN) wihin road vehicles is described by he inernaional sandard ISO According o he 7-layer OSI reference model he physical layer of a HS CAN bus sysem specifies he daa ransmission from one CAN node o all oher available CAN nodes wihin he nework. The physical layer specificaion of a CAN bus sysem includes all elecrical specificaions of a CAN nework. The CAN ransceiver is par of he physical layer specificaion. Several differen physical layer sandards of CAN neworks have been developed in recen years. 4.1 High-speed CAN physical layer TxD CANH CANL VIO VCC VIO = Digial supply volage VCC = Transmier supply volage TxD = Transmi daa inpu from he microconroller RxD = Receive daa oupu o he microconroller CANH = Bus level on he CANH inpu/oupu CANL = Bus level on he CANL inpu/oupu VDiff = Differenial volage beween CANH and CANL VDiff = VCANH VCANL VDiff VCC dominan receiver hreshold recessive receiver hreshold RxD VIO Loop(H,L) Loop(L,H) Figure 3 High-speed CAN bus signals and logic signals Daa Shee 6 Rev. 1.1

7 High-speed CAN funcional descripion The is a high-speed CAN ransceiver, operaing as an inerface beween he CAN conroller and he physical bus medium. A HS CAN nework is a wo wire, differenial nework which allows daa ransmission raes up o 5 MBi/s. The characerisic for a HS CAN nework are he wo signal saes on he CAN bus: dominan and recessive (see Figure 3). The CANH and CANL pins are he inerface o he CAN bus and boh pins operae as an inpu and oupu. The RxD and TxD pins are he inerface o he microconroller. The pin TxD is he serial daa inpu from he CAN conroller, he RxD pin is he serial daa oupu o he CAN conroller. As shown in Figure 1, he HS CAN ransceiver includes a receiver and a ransmier uni, allowing he ransceiver o send daa o he bus medium and monior he daa from he bus medium a he same ime. The HS CAN ransceiver convers he serial daa sream which is available on he ransmi daa inpu TxD, ino a differenial oupu signal on he CAN bus, provided by he CANH and CANL pins. The receiver sage of he moniors he daa on he CAN bus and convers hem o a serial, single-ended signal on he RxD oupu pin. A logical low signal on he TxD pin creaes a dominan signal on he CAN bus, followed by a logical low signal on he RxD pin (see Figure 3). The feaure, broadcasing daa o he CAN bus and lisening o he daa raffic on he CAN bus simulaneously is essenial o suppor he bi-o-bi arbiraion wihin CAN neworks. The volage levels for HS CAN ransceivers are defined in ISO Wheher a daa bi is dominan or recessive depends on he volage difference beween he CANH and CANL pins: V Diff = V CANH - V CANL. To ransmi a dominan signal o he CAN bus he ampliude of he differenial signal V Diff is higher han or equal o 1.5 V. To receive a recessive signal from he CAN bus he ampliude of he differenial V Diff is lower han or equal o 0.5 V. Parially-supplied high-speed CAN neworks are hose where he CAN bus nodes of one common nework have differen power supply condiions. Some nodes are conneced o he common power supply, while oher nodes are disconneced from he power supply and in power-down sae. Regardless of wheher he CAN bus subscriber is supplied or no, each subscriber conneced o he common bus media mus no inerfere wih he communicaion. The is designed o suppor parially-supplied neworks. In power-down sae, he receiver inpu resisors are swiched off and he ransceiver inpu has a high resisance. For permanenly supplied ECU's, he HS CAN ransceiver provides a Power-save mode. In Powersave mode, he power consumpion of he is opimized o a minimum The volage level on he digial inpu TxD and he digial oupu RxD is deermined by he power supply level a he V IO pin. Depending on he volage level a he V IO pin, he signal levels on he logic pins (STB, TxD and RxD) are compaible wih microconrollers having a 5 V or 3.3 V I/O supply. Usually he digial power supply V IO of he ransceiver is conneced o he I/O power supply of he microconroller (see Figure 15). Daa Shee 7 Rev. 1.1

9 Modes of operaion 5.1 Normal-operaing mode In Normal-operaing mode he ransceiver sends and receives daa from he HS CAN bus. All funcions are acive (see also Figure 4 and Table 2): The ransmier is acive and drives he serial daa sream on he TxD inpu pin o he bus pins CANH and CANL. The normal-mode receiver is acive and convers he signals from he bus o a serial daa sream on he RxD oupu. The RxD oupu pin indicaes he daa received by he normal-mode receiver. The bus biasing is conneced o V CC /2. The NEN inpu pin is acive and changes he mode of operaion. The TxD ime-ou funcion is enabled and disconnecs he ransmier in case a ime-ou is deeced. The overemperaure proecion is enabled and disconnecs he ransmier in case an overemperaure is deeced. The undervolage deecion on V CC is enabled and riggers a mode change o Forced-receive-only in case an undervolage even is deeced. The undervolage deecion on V IO is enabled and powers down he device in case of deecion. Normal-operaing mode is enered from Power-save mode and Forced-receive-only mode, when he NEN inpu pin is se o logical low. Normal-operaing mode can only be enered when all supplies are available: The ransmier supply V CC is available (V CC > V CC(UV,R) ). The digial supply V IO is available (V IO > V IO(UV,R) ). 5.2 Forced-receive-only mode The Forced-receive-only mode is a fail-safe mode of he, which will be enered when he ransmier supply V CC is no available. The following funcions are available (see also Figure 4 and Table 2): The ransmier is disabled and he daa available on he TxD inpu is blocked. The normal-mode receiver is enabled. The RxD oupu pin indicaes he daa received by he normal-mode receiver. The bus biasing is conneced o GND. The NEN inpu pin is acive and changes he mode of operaion o Power-save mode, if logical high. The TxD ime-ou funcion is disabled. The overemperaure proecion is disabled. The undervolage deecion on V CC is acive. The undervolage deecion on V IO is enabled and powers down he device in case of deecion. Forced-receive-only mode is enered from power-down sae if he NEN inpu pin is se o logical low and he digial supply V IO is available (V IO > V IO(UV,R) ). Forced-receive-only mode is enered from Normal-operaing mode by an undervolage even on he ransmier supply V CC. 5.3 Power-save mode In Power-save mode he ransmier and receiver are disabled. (see also and Table 2): The ransmier is disabled and he daa available on he TxD inpu is blocked. The receiver is disabled and he daa available on he bus is blocked. Daa Shee 9 Rev. 1.1

10 Modes of operaion The RxD oupu pin is permanenly se o logical high. The bus biasing is floaing. The NEN inpu pin is acive and changes he mode of operaion o Normal-operaing mode, if logical low and V CC (V CC > V CC(UV,R) ) is available. The overemperaure proecion is disabled. The undervolage deecion on V CC is disabled. In Power-save mode he device can operae wihou he ransmier supply V CC. The undervolage deecion on V IO is enabled and powers down he device in case of deecion. 5.4 Power-down sae Independen of he ransmier supply V CC and of he saus a NEN inpu pin he is powered down if he supply volage V IO < V IO(UV,F) (see Figure 4). In he power-down sae he differenial inpu resisors of he receiver are swiched off. The CANH and CANL bus inerface of he is floaing and acs as a high-impedance inpu wih a very small leakage curren. The high-ohmic inpu does no influence he recessive level of he CAN nework and allows an opimized EME performance of he enire HS CAN nework. In power-down sae he ransceiver is an invisible node o he bus. Daa Shee 10 Rev. 1.1

11 Changing he mode of operaion 6 Changing he mode of operaion 6.1 Power-up and power-down The HS CAN ransceiver powers up by applying he digial supply V IO o he device (V IO > V IO(U,R) ). Afer powering up, he device eners one ou of hree operaing modes (see Figure 5 and Figure 6). Depending on he condiion of he ransmier supply volage V CC and he mode selecion pin NEN he device can ener every mode of operaion afer he power-up: V CC is available and he NEN inpu is se o low - Normal-operaing mode The NEN inpu is se o high - Power-save mode V CC is disabled and he NEN inpu is se o low - Forced-receive-only mode The device powers down when he V IO supply falls below he undervolage deecion hreshold (V IO < V IO(U,F) ), regardless if he ransmier supply V CC is available or no. The power-down deecion is acive in every mode of operaion.

12 Changing he mode of operaion 6.2 Mode change by he NEN pin When he is supplied wih he digial volage V IO he inernal logic works and mode change by he mode selecion pin NEN is possible. By defaul he NEN inpu pin is logical high due o he inernal pull-up curren source o V IO. Changing he NEN inpu pin o logical low in Power-save mode riggers a mode change o Normal-operaing mode (see Figure 7). To ener Normal-operaing mode he ransmier supply V CC needs o be available. Power-save mode can be enered from Normal-operaing mode and from Forced-receive-only mode by seing he NEN pin o logical high. Enering Forced-receive-only mode from Power-save mode is no possible by he NEN pin. The device remains in Power-save mode independenly of he V CC supply volage.

13 Changing he mode of operaion 6.3 Mode changes by V CC undervolage When he ransmier supply V CC (V CC < V CC(U/F) ) is in undervolage condiion, he migh no be able o provide he correc bus levels on he CANH and CANL oupu pins. To avoid any inerference wih he nework he blocks he ransmier and changes he mode of operaion when an undervolage even is deeced (see Figure 8 and Figure 9). In Normal-operaing mode a undervolage even on ransmier supply V CC (V CC < V CC(U/F) ) riggers a mode change o Forced-receive-only mode. In Forced-receive-only mode he undervolage deecion V CC (V CC < V CC(U/F) )is enabled. In Power-save mode he undervolage deecion is disabled. In hese modes he can operae wihou he ransmier supply V CC.

A curren limiing circui proecs he ransceiver agains damages. If he device is heaing up due o a coninuous shor on he CANH or CANL, he inernal overemperaure proecion swiches off he bus ransmier. 7.2 Unconneced logic pins All logic inpu pins have an inernal pull-up curren source o V IO. In case he V IO and V CC supply is acivaed and he logical pins are open, he eners ino he Power-save mode by defaul. 7.3 TxD ime-ou funcion The TxD ime-ou feaure proecs he CAN bus agains permanen blocking in case he logical signal on he TxD pin is coninuously low. A coninuous low signal on he TxD pin migh have is roo cause in a lockedup microconroller or in a shor circui on he prined circui board, for example. In Normal-operaing mode, a logical low signal on he TxD pin for he ime > TxD enables he TxD ime-ou feaure and he disables he ransmier (see Figure 10). The receiver is sill acive and he daa on he bus coninues o be moniored by he RxD oupu pin. TxD CANH CANL > TxD TxD ime-ou TxD ime ou released RxD Figure 10 TxD ime-ou funcion Figure 10 illusraes how he ransmier is deacivaed and acivaed again. A permanen low signal on he TxD inpu pin acivaes he TxD ime-ou funcion and deacivaes he ransmier. To release he ransmier afer a TxD ime-ou even, he requires a signal change on he TxD inpu pin from logical low o logical high. Daa Shee 14 Rev. 1.1

The overemperaure proecion is only acive in Normal-operaing mode. In case of an overemperaure condiion, he emperaure sensor will disable he ransmier while he ransceiver remains in Normal-operaing mode. Afer he device has cooled down he ransmier is acivaed again (see Figure 11). A hyseresis is implemened wihin he emperaure sensor.
