6 Funcional Descripion 4 Funcional Descripion CAN is a serial bus sysem ha connecs microconrollers, sensor and acuaors for real-ime conrol applicaions. The usage of he Conrol 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 CAN bus sysem specifies he daa ransmission from one CAN node o all oher available CAN nodes inside he nework. The physical layer specificaion of a CAN bus sysem includes all elecrical and mechanical specificaions of a CAN nework. The CAN ransceiver is par of he physical layer specificaion. Several differen physical layer definiions of a CAN nework have been developed over he las years. The TLE8250G is a High Speed CAN ransceiver wihou any dedicaed Wake-Up funcion. High Speed CAN Transceivers wihou Wake-Up funcion are defined by he inernaional sandard ISO High Speed CAN Physical Layer TxD CAN_H CAN_L = CAN Power Supply TxD = Inpu from he Microconroller RxD = Oupu o he Microconroller CANH = Volage on he CANH Inpu/Oupu CANL = Volage on he CANL Inpu/Oupu V DIFF = Differenial Volage beween CANH and CANL V DIFF = V CANH V CANL V DIFF Dominan V DIFF = ISO Level Dominan Recessive V DIFF = ISO Level Recessive RxD Figure 3 High Speed CAN Bus Signals and Logic Signals Daa Shee 6 Rev. 1.1,

7 Funcional Descripion The TLE8250G 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 1 MBi/s. Characerisic for a HS CAN nework are he wo signal saes on he CAN bus: Dominan and Recessive (see Figure 3). The pins CANH and CANL are he inerface o he CAN bus and boh pins operae as an inpu and as an oupu. The pins RxD and TxD are he inerface o he microconroller. The pin TxD is he serial daa inpu from he CAN conroller, he pin RxD is he serial daa oupu o he CAN conroller. As shown in Figure 1, he HS CAN ransceiver TLE8250G has a receive and a ransmi 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 TLE8250G convers he serial daa sream available on he ransmi daa inpu TxD, ino a differenial oupu signal on CAN bus, provided by he pins CANH and CANL. The receiver sage of he TLE8250G 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 simulaneous is essenial o suppor he bi o bi arbiraion inside CAN neworks. The volage levels for HS CAN ransceivers are defined by he ISO and he ISO sandards. If a daa bi is Dominan or Recessive depends on he volage difference beween pins CANH and CANL: V DIFF = V CANH - V CANL. In comparison o oher differenial nework proocols he differenial signal on a CAN nework can only be larger or equal o 0 V. To ransmi a Dominan signal o he CAN bus he differenial signal V DIFF is larger or equal o 1.5 V. To receive a Recessive signal from he CAN bus he differenial V DIFF is smaller or equal o 0.5 V. Parially supplied CAN neworks are neworks where he CAN bus paricipans have differen power supply condiions. Some nodes are conneced o he power supply, some oher nodes are disconneced from he power supply. Regardless, if he CAN bus paricipan is supplied or no supplied, each paricipan conneced o he common bus media mus no disurb he communicaion. The TLE8250G is designed o suppor parially supplied neworks. In Power Down mode, he receiver inpu resisors are swiched off and he ransceiver inpu is high resisive. Daa Shee 7 Rev. 1.1,

8 Funcional Descripion 4.2 Operaion Modes Three differen operaion modes are available on TLE8250G. Each mode wih specific characerisics in erms of quiescen curren or daa ransmission. For he mode selecion he digial inpu pins NEN and NRM are used. Figure 4 illusraes he differen mode changes depending on he saus of he NEN and NRM pins. Afer suppling o he HS CAN ransceiver, he TLE8250G sars in Sand-By mode. The inernal pull-up resisors are seing he TLE8250G o Sand-By per defaul. If he microconroller is up and running he TLE8250G can change o any operaion mode wihin he ime for mode change Mode.

9 Funcional Descripion 4.3 Normal Operaion Mode In Normal Operaion mode he HS CAN ransceiver TLE8250G sends he serial daa sream on he TxD pin o he CAN bus while a he same ime he daa available on he CAN bus are moniored o he RxD pin. In Normal Operaion mode all funcions of he TLE8250G are acive: The oupu driver sage is acive and drives daa from he TxD o he CAN bus. The receiver uni is acive and provides he daa from he CAN bus o he RxD pin. The bus basing is se o /2. The under-volage monioring on he power supply is acive. To ener he Normal Operaion mode se he pin NRM o logical High and he pin NEN o logical Low (see Table 2 or Figure 4). Boh pins, he NEN pin and he NRM pin have inernal pull-up resisors o he power-supply. 4.4 Receive-Only Mode The Receive-Only mode can be used o es he connecion of he bus medium. The TLE8250G can sill receive daa from he bus, bu he oupu driver sage is disabled and herefore no daa can be sen o he CAN bus. All oher funcions are acive: The oupu driver sage is disabled and daa which are available on he TxD pin are blocked and no send o he CAN bus. The receiver uni is acive and provides he daa from he CAN bus o he RxD oupu pin. The bus basing is se o /2. The under-volage monioring on he power supply is acive. To ener he Receive-Only mode se he pin NRM o logical Low and he pin NEN o logical Low (see Table 2 or Figure 4). In case he Receive-Only mode will no be used, he NRM pin can be lef open. 4.5 Sand-By Mode Sand-By mode is an idle mode of he TLE8250G wih opimized power consumpion. In Sand-By mode he TLE8250G can no send or receive any daa. The oupu driver sage and he receiver uni are disabled. Boh CAN bus pins, CANH and CANL are floaing. The oupu driver sage is disabled. The receiver uni is disabled. The bus basing is floaing. The under-volage monioring on he power supply is acive. To ener he Sand-By mode se he pin NEN o logical High, he logical sae of he NRM pin has no influence for he mode selecion (see Table 2 or Figure 4). Boh pins he NEN and he NRM pin have an inernal pull-up resisor o he power-supply. If he Sand-By mode is no used in he applicaion, he NEN pin needs o ge conneced o. In case he NRM pin is se o logical Low in Sand-By mode, he inernal pull-up resisor causes an addiional quiescen curren from o, herefore i is recommended o se he NRM pin o logical High in Sand-By mode or leave he pin open if he Receive-Only mode is no used in he applicaion. 4.6 Power Down Mode Power Down mode means he TLE8250G is no supplied. In Power Down he differenial inpu resisors of he receiver sage are swiched off. The CANH and CANL bus inerface of he TLE8250G acs as an high impedance inpu wih a very small leakage curren. The high ohmic inpu doesn influence he Recessive level of he CAN nework and allows an opimized EME performance of he whole CAN nework. Daa Shee 9 Rev. 1.1,

10 Fail Safe Funcions 5 Fail Safe Funcions 5.1 Shor circui proecion The CANH and CANL bus oupus are shor-circui-proof, eiher agains or a posiive supply volage. A curren limiing circui proecs he ransceiver agains damages. If he device is heaing up due o a coninuos shor on CANH or CANL, he inernal over-emperaure proecion swiches off he bus ransmier. 5.2 Open Logic Pins All logic inpu pins have inernal pull-up resisor o. In case he supply is acivaed and he logical pins are open or floaing, he TLE8250G eners ino he Sand-By mode per defaul. In Sand-By mode he oupu driver sage of he TLE8250G is disabled, he bus biasing is shu off and he HS CAN ransceiver TLE8250G will no influence he daa on he CAN bus. 5.3 TxD Time-Ou funcion The TxD Time-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 can have i s roo cause in a locked-up microconroller or in a shor on he prined circui board for example. In Normal Operaion mode, a logical Low signal on he TxD pin for he ime > TXD he TLE8250G acivaes he TxD Time-ou and he TLE8250G disables he oupu driver sage (see Figure 5). The receive uni is sill acive and he daa on he bus are moniored a he RxD oupu pin. CANH CANL > TxD TxD Time - Ou TxD Time Ou released TxD RxD Figure 5 TxD Time-Ou funcion Figure 5 shows how he oupu driver sage is deacivaed and acivaed again. A permanen Low signal on he TxD inpu pin acivaes he TxD ime-ou funcion and deacivaes he oupu driver sage. To release he oupu driver sage afer a TxD ime-ou even he TLE8250G requires a signal change on he TxD inpu pin from logical Low o logical High. 5.4 Under-Volage deecion The HS CAN Transceiver TLE8250G is equipped wih an under-volage deecion on he power supply. In case of an under-volage even on, he under-volage deecion changes he operaion mode of TLE8250G o he Sand-By mode, regardless of he logical signal on he pins NEN and NRM (see Figure 6). If he ransceiver TLE8250G recovers from he under-volage even, he operaion mode reurns o he programmed mode by he logical pins NEN and NRM. Daa Shee 10 Rev. 1.1,

20 Applicaion Informaion 8.2 Oupu Characerisics of he RxD Pin The RxD oupu pin is designed as a push-pull oupu sage (see Figure 1), meaning o produce a logical Low signal he TLE8250G swiches he RxD oupu o. Vice versa o produce a logical High signal he TLE8250G swiches he RxD oupu o. The level V RxD,H for a logical High signal on he RxD oupu depends on he load on he RxD oupu pin and herefore on he RxD oupu curren I RD,H. For a load agains he poenial, he curren I RD,H is flowing ou of he RxD oupu pin. Similar o he logical High signal, he level V RxD,L for a logical Low signal on he RxD oupu pin depends on he oupu curren I RD,L. For a load agains he power supply he curren I RD,L is flowing ino he RxD oupu pin.
