The TLE7250X is a transceiver designed for HS CAN networks in automotive and industrial applications. As an interface between the physical bus layer and the CAN protocol controller, the TLE7250X drives the signals to the bus and protects the microcontroller against interferences generated within the network. Based on the high symmetry of the CANH and CANL signals, the TLE7250X provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE7250X is available in a small, leadless PG-TSON-8 package and in a PG-DSO-8 package. Both packages are RoHS compliant and halogen free. Additionally the PG-TSON-8 package supports the solder joint requirements for automated optical inspection (AOI). The TLE7250XLE and the TLE7250XSJ are fulfilling or exceeding the requirements of the ISO11898-2. The TLE7250X provides a digital supply input V IO and a receive-only mode. It is designed to fulfill the enhanced physical layer requirements for CAN FD and supports data rates up to 2 MBit/s. On the basis of a very low leakage current on the HS CAN bus interface the TLE7250X provides an excellent passive behavior in power-down state. These and other features make the TLE7250X exceptionally suitable for mixed supply HS CAN networks. TLE7250XLE TLE7250XSJ Overview Data Sheet 4 Rev. 1.0, 2015-08-12 Based on the Infineon Smart Power Technology SPT, the TLE7250X provides excellent ESD immunity together with a very high electromagnetic immunity (EMI). The TLE7250X and the Infineon SPT technology are AEC qualified and tailored to withstand the harsh conditions of the automotive environment. Two different operating modes, additional fail-safe features like a TxD time-out and the optimized output slew rates on the CANH and CANL signals, make the TLE7250X the ideal choice for large HS CAN networks with high data transmission rates.
