TLE9351BVSJ | High speed CAN Transceivers with up to 8Mb/s transmission speed for automotive & many other applications.

Überblick

The TLE9351BVSJ is a high speed CAN transceiver, used in HS CAN systems for automotive applications as well as for industrial applications. It is designed to fulfill the requirements of ISO 11898-2:2016 physical layer specification as well as SAE J1939 and SAE J2284. The TLE9351BVSJ is available in a RoHS compliant, halogen free PG-DSO-8 package. As an interface between the physical bus layer and the HS CAN protocol controller, the TLE9351BVSJ is designed to protect the microcontroller against interferences generated inside the network. A very high ESD robustness and the optimized RF immunity allows the use in automotive applications without additional protection devices, such as suppressor diodes or common mode chokes. Based on the high symmetry of the CANH and CANL output signals, the TLE9351BVSJ provides a very low level of electromagnetic emission (EME) within a wide frequency range. The TLE9351BVSJ fulfills even stringent EMC test limits without an additional external circuit, such as a common mode choke. The optimized transmitter symmetry combined with the optimized delay symmetry of the receiver enables the TLE9351BVSJ to support CAN FD data frames. The device supports data transmission rates up to 5 Mbit/s, depending on the size of the network and the inherent parasitic effects. Dedicated low-power modes, such as standby mode, provide very low quiescent current during power-up of the device. In standby mode the typical quiescent current on VIO is less than 10 µA while the device can still wake up by a bus signal on the HS CAN bus. Fail-safe features, such as overtemperature protection, output current limitation or the TxD timeout feature are designed to protect the TLE9351BVSJ and the external circuitry from irreparable damage.
