It is designed to fulfill the requirements of ISO 11898-2 (2016) physical layer specification and respectively also the SAE standards J1939 and J2284. The TLE9251 is available in a PG-DSO-8 package and in a small, leadless PG-TSON-8 package. Both packages are RoHS compliant and halogen free. The PG-TSON-8 package 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 TLE9251 protects the microcontroller against interferences generated inside the network. A very high ESD robustness and the perfect RF immunity allows the use in automotive applications without adding additional protection devices, like suppressor diodes for example. While the transceiver TLE9251 is not supplied the bus is switched off and illustrates 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 output signals, the TLE9251 provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE9251 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 TLE9251 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. Dedicated low-power modes, like Stand-by mode provide very low quiescent currents while the device is powered up. In Stand-by mode the typical quiescent current on V is below 10 A while the device can still be CC woken up by a bus signal on the HS CAN bus. Fail-safe features like overtemperature protection, output current limitation or the TxD time-out feature protect the TLE9251 and the external circuitry from irreparable damage.
