Infineon Technologies TLT9252VLC High-Speed CAN FD Transceiver

Infineon Technologies TLT9252VLC High-Speed CAN FD Transceiver is designed for HS CAN networks up to 5Mbit/s in automotive and industrial applications. As an interface between the physical bus layer and the CAN protocol controller, the TLT9252VLC 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 TLT9252VLC provides very low electromagnetic emission allowing the operation without a common mode choke. The non-low power modes (Normal-operating Mode and Receive-only Mode) and low power modes (Sleep Mode and Standby Mode) are optimized for reduced current consumption based on the required functionality. Even in Sleep Mode with a quiescent current below 25µA over the entire temperature range, the TLT9252VLC can detect a Wake-Up Pattern (WUP) on the HS CAN bus. The VIO voltage reference input supports 3.3V and 5V supplied microcontrollers. The Infineon Technologies TLT9252VLC is integrated into a RoHS-compliant PG-TSON-14 package and fulfills the requirements of the ISO11898-2 (2016).
