描述 Description

The TPT1145 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 crosswire, overvoltage, and loss of ground protection from -70 V to +70 V, over-temperature shutdown, and a -30-V to +30-V common-mode input voltage range. The TPT1145 has a secondary power supply input for I/O level shifting the input pin thresholds and RXD output level. A serial peripheral interface (SPI) is provided for configuration and status retrieve. TPT1145 supports selective wake up and enables the Electronic Control Unit (ECU) to implement the partial networking function which is operating in an active state while it is in a low-power sleep mode. The device comes with the standby mode, which can be waked up from the CAN bus, and ultra-low power management controls the ECU in standby and sleep modes, then enable the power supply by inhibit output through the local or remote wake-up via wake-up pattern or wake-up frame identification. TPT1145 includes many protection features to enhance device and network robustness. There are two versions of the device, TPT1145Q and TPT1145NQ, the difference between the two versions is that the Device ID is different.

TPT1145 is available in SOP14 and DFN4.5X3.0-14L packages, and is characterized from –40°C to +125°C.
