Product validation according to AEC-Q100. Description Type Package Marking TLT9251VLE PG-TSON-8 T9251V The TLT9251VLE is the latest Infineon high-speed CAN transceiver generation, used inside HS CAN networks for automotive and also for industrial applications. 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 TLT9251VLE is available in a small, leadless PG-TSON-8 package. The PG-TSON-8 package supports the solder joint requirements for automated optical inspection (AOI)and is RoHS compliant and halogen free. As an interface between the physical bus layer and the HS CAN protocol controller, the TLT9251VLE 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 TLT9251VLE 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 TLT9251VLE provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLT9251VLE 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 TLT9251VLE 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 IO 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 TLT9251VLE and the external circuitry from irreparable damage.
