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.
