It is designed to fulfill the requirements of the current ISO11898 standard (ISO11898-2 from 2003 and ISO11898-5 from 2007) and also the upcoming new version of ISO 11898-2 (2016) physical layer specification. Additionally it also fulfills the SAE standards J1939 and J2284-4/5. The TLE9251VSJ has a low power Stand-by mode with bus wake-up pattern (WUP) detection feature according to ISO 11898-2 (2016). In Stand-by mode the TLE9251VSJ is capable to detect a wake-up pattern even if VIOis the only supply voltage available (VCCswitched off). The TLE9251VSJ is offered in the standard PG-DSO-8 package, but is also available in a tiny, leadless PG-TSON-8 package, called TLE9251VLE. Both packages are RoHS compliant and halogen free. Additionally the PG-TSON-8 package supports the solder joint requirements for reliable automated optical inspection (AOI). As an interface between the physical bus layer and the HS CAN protocol controller, the TLE9251VSJ 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 adding additional protection devices, like suppressor diodes for example. Based on the high symmetry of the CANH and CANL output signals, the TLE9251VSJ provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE9251VSJ fulfills even stringent EMC test limits without additional external circuit, like a common mode choke for example. The perfect transmitter symmetry combined with the optimized delay symmetry of the receiver enables the TLE9251VSJ to support CAN FD data frames. Depending on the size of the network and the along coming parasitic effects the device supports bit rates up to 5 MBit/s. Fail-safe features like overtemperature protection, output current limitation or the TxD timeout feature protect the TLE9251VSJ and the external circuitry. While the transceiver TLE9251VSJ is not supplied 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.
