TLE7250LE

CAN 接口集成电路 TRANSCEIVER

Description:

The TLE7250 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 TLE7250 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 TLE7250 provides a very low level of electromagnetic emission EME within a wide frequency range. The TLE7250 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 and the TLE7250SJ are fulfilling or exceeding the requirements of the ISO11898-2. The TLE7250 provides a receive-only mode and a power-save 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 TLE7250 provides an excellent passive behavior in power-down state. These and other features make the TLE7250 exceptionally suitable for mixed supply HS CAN networks. Based on the Smart Power Technology SPT, the TLE7250 provides excellent ESD immunity together with TLE7250LE TLE7250SJ Overview Data Sheet 4 Rev. 1.0, 2015-08-12 a very high electromagnetic immunity EMI. The TLE7250 and the Infineon SPT technology are AEC qualified and tailored to withstand the harsh conditions of the automotive environment. Three 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 TLE7250 the ideal choice for large HS CAN networks with high data transmission rates.
