Product validation according to AEC-Q100. Description As an interface between the physical bus layer and the CAN protocol controller, the TLT9255W drives the signals to the bus and protects the microcontroller from interference generated within the network. Based on the high symmetry of the CANH and CANL signals, the TLT9255W provides a very low level of electromagnetic emission within a wide frequency range, allowing the operation of the TLT9255W without a common mode choke in automotive and industrial applications. The TLT9255W is enclosed in an RoHS compliant PG-TSON-14 package and fulfills the requirements of the ISO11898-2 (2016). The TLT9255W is part of the Infineon standard HS CAN transceiver family and provides beside CAN partial networking functions also a CAN FD capability up to 5 MBit/s in HS CAN networks. Configured as a partial networking HS CAN transceiver the TLT9255W can drive and receive CAN FD messages. it can also be used to block the payload of CAN FD messages. This CAN FD tolerant feature allows the usage of microcontrollers in CAN FD networks, which are not CAN FD capable. The SPI of TLT9255W controls the setup of the wake-up messages and the status message generated by the internal state machine. Most of the functions, including wake-up functions, INH output control, mode control, undervoltage control are configurable by the SPI. This allows a very flexible usage of the TLT9255W in different applications. The two non-low power modes (Normal-operating Mode and Receive-only Mode) and the two low power modes (Sleep Mode and Stand-by Mode) provide minimum current consumption based on the required functionality. In Sleep Mode the TLT9255W can detect a wake-up pattern (WUP) on the HS CAN and then change the mode of operation accordingly even at a quiescent current below 26 A over the full temperature range. In Selective-wake Sub-mode the TLT9255W monitors the CAN messages on the HS CAN bus. If the TLT9255W detects a matching wake-up frame, then it triggers a mode change. The TLT9255W monitors wake-up identifiers up to 29 bit as well as up to 64 bit wide data. The internal protocol handler counts all bus errors. The SPI indicates failures, error counter overflow and synchronization failures to the microcontroller. The unique power-supply management allows the application to use the TLT9255W without the battery supply V connected. In this case the TLT9255W is supplied over the V pin. The V voltage reference BAT CC IO supports 3.3 V and 5 V supplied microcontrollers. Based on Infineon Smart Power Technology (SPT), the TLT9255W provides excellent immunity together with a very high electromagnetic immunity (EMI). The TLT9255W and the Infineon SPT are AEC qualified and tailored to withstand the harsh conditions of the automotive environment.
