The device is primarily designed for use in single wire CAN sysems operaing wih various CSMA/CR (carrier sense muliple access/collision resoluion) proocols such as he BOSCH Conroller Area Nework (CAN). The normal communicaion birae in CAN-sysems is up o 33 kbi/s. For sofware or diagnosic daa download a high speed mode is offered ha allows ransmission raes up o 100 kbi/s. Wih many inegraed feaures such as slewrae conrolled oupu, loss of ground circui, bi-level wake-up and sleep mode for low power consumpion he TLE 6255 G is opimized for use in auomoive applicaions. The device is based on Siemens power echnology SPT which allows bipolar and CMOS conrol circuiry o be inegraed wih DMOS power devices on he same monolihic circuiry. Addiional feaures like shor circui and overemperaure proecion, over- and undervolage lockou are inegraed. To enhance he reliabiliy and robusness of he TLE 6255 G he enhanced power SO-14 package is used in order o provide high hermal capaciy and low hermal resisance. Daa Shee Rev

5 6 Funcional Descripion and Applicaion Hins 6.1 Mode Conrol By use of he wo mode conrol pins M0 and M1 he ransceiver can be se in he following modes. Table 1 Transceiver Modes # M0 M1 Mode 1 Low Low Sleep mode 2 High Low High speed mode 3 Low High Wake-up call 4 High High Normal mode Sleep-Mode In he sleep mode he oal curren consumpion of he TLE 6255 G is reduced o ypically 30 µa. Nodes no se o sleep mode can communicae wihou disurbing ECUs ha are already se o sleep mode. To achieve a wake-up via he CAN bus a high volage level message (wake-up call) is necessary. Only high volage level messages are repored o he RxD pin in sleep mode. A wake-up from sleep mode of he ransceiver iself has o be done by seing he conrol inpus M0 and M1. If here is no modificaion on he mode inpus he device remains in sleep mode afer he wake-up signal is removed from he bus. The ransceiver s loss of ground proecion circui connecion o ground is no inerruped when in he sleep mode. High-Speed-Mode The high-speed mode can be used for sofware or diagnosic daa download wih biraes up o 100 kbi/s. Therefore he slewrae conrol feaure is deacivaed o achieve he required imings. Furher an addiional exernal resisor of 100 Ω from CANH o GND is necessary in his mode. Wakeup-Call Mode In his mode he TLE 6255 G sends he message o be ransmied as a high volage wake-up message. The bus includes a special node wake up capabiliy which allows normal communicaion o ake place among some nodes while leaving he oher nodes in an undisurbed sleep sae. This is accomplished by conrolling he level of he signal volages such ha all nodes mus wake up when hey receive a higher volage message signal waveform. Communicaion a he lower, normal volage levels shall no disurb he sleeping nodes (V ba >9V). Daa Shee Rev

6 Normal Mode In he normal mode he TLE 6255 G sends a normal volage message waveform on he bus. I is possible o run he ransceiver up o ransmission raes of 33 kbis/s in his mode. The waveform as well as he slew rae of he rising edge (recessive o dominan ransiion) are conrolled by he inernal acive wave shaping circui o minimize EME (elecromagneic emission). For he same reason waveform railing edge conrol is required o assure ha high frequency conen is minimized a he beginning of he downward volage slope (dominan o recessive ransiion). The remaining fall ime occurs afer he bus is inacive wih drivers off and is deermined by he RC ime consan of he oal bus load. 6.2 Slew-Rae Conrol The CANH oupu volage and curren is conrolled by an inernal waveshaping circui. For opimized adjusing of he slew rae o he sysem iming, he slew rae is programmable by an exernal resisor conneced from pin RSL o V CC. Figure 4 shows he correlaion of he slew rae o he resisor R RSL. 6.3 Transmier The TLE 6255 G conains a high curren fully shor circui and overemperaure proeced highside-driver (pin CANH). To minimize specral conen he CANH-oupu waveform is conrolled. Logic low (TxD = L) on pin TxD will command he oupu sage o swich o dominan high poenial; TxD = H o recessive low on he bus. To avoid he bus o be blocked by a permanen dominan TxD inpu signal, he TLE 6255 G incorporaes a imeou feaure. In case of TxD = L for longer han he inernal fixed imeou he CANH oupu is swiched off auomaically. The imeou is reseed by a H-signal a TxD wihou a delay. The loss of an ECU ground may cause he ECU o source curren hrough he various ECU circuis o he communicaions bus insead of o he vehicle sysem ground. Therefore he uni-load resisor of any ECU is conneced o he LOAD-pin. The TLE 6255 G incorporaes a reverse proeced swich from LOAD o ground poenial. This swich is auomaically swiched off in a loss of ground sae. 6.4 Receiver In normal, high speed and wakeup-mode all daa on he bus is sensed by he receive comparaor and ransmied o he RxD oupu. In sleep mode no normal level daa is deeced. The receiver hreshold is se o he wake-up level. So a wake-up inerrup is sen only in case of a wake-up call on he bus. An inernal fixed filer improves he EMC suscepibiliy. Daa Shee Rev
