Low-Power Fault Protected High-Speed CAN FD Transceiver with Sleep Mode


The TPT1043 is a CAN transceiver that meets the ISO11898 high-speed CAN (Controller Area Network) physical layer standard. The device is designed to be used in CAN FD networks up to 5 Mbps, with enhanced timing margin and higher data rates in long and highly loaded networks. As designed, the device features a –30-V to +30-V common-mode range, CAN-Bus fault protection from -70 V to +70 V, over-voltage protection, and over-temperature shutdown. TPT1043 has an I/O power supply for interface I/O to connect to microcontrollers with supply voltages from 2.8 V to 5.5 V. The device comes with a standby mode, which can be waked up from the CAN BUS. The ultra-low power management controls the node in standby and sleep modes. The device enables the power supply by the INH interface through the local and remote wake-up with wake-up source recognition, and it includes many protection features to enhance the device and network robustness.

The TPT1043 is available in SOP14 and DFN4.5X3.0-14L packages, and is characterized from -40°C to +125°C.
