申报技术丨TPT1145Q CAN FD收发器

产品描述：

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.

独特优势：

BUS耐压±70V，ESD IEC 61000-4-2能力10kV

应用场景：

座舱、动力、车身等零部件的基础接口物料

未来前景：

CAN收发器是车用基础通讯接口芯片，平均单车用量超过30颗。
