Infineon Technologies TLT9251VLE High-Speed CAN FD Transceiver
Infineon Technologies TLT9251VLE High-Speed CAN (Controller Area Network) FD (Flexible Data-rate) Transceiver features a flexible data rate of up to 5MB and is AEC-Q100 Grade 0 qualified for automotive applications. The TLT9251VLE Transceiver is designed to fulfill the requirements of ISO 11898-2 (2016) physical layer specification and respectively, also the SAE (Society of Automotive Engineering) standards J1939 and J2284. As an interface between the physical bus layer and the HS CAN protocol controller, the TLT9251VLE protects the microcontroller against interference generated inside the network. A very high ESD robustness and high RF immunity allow this device to be used in automotive applications without adding additional protection devices.
Based on the high symmetry of the CANH and CANL output signals, the TLT9251VLE provides a very low electromagnetic emission (EME) level within a wide frequency range.
The optimized transmitter and delay symmetry of the receiver enable the TLT9251VLE to support CAN FD data frames. Depending on the size of the network and the associated parasitic effects, the device supports bit rates up to 5MBit/s.
Dedicated low-power modes provide very low quiescent currents while the device is powered up. In Stand-by mode, the typical quiescent current on VIO is below 10µA, but the device can still be 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.
The Infineon Technologies TLT9251VLE is available in a small, leadless PG-TSON-8 package. This device supports the solder joint requirements for automated optical inspection (AOI) and is RoHS-compliant and halogen-free.
