Description

The TPT125x device 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, and to enhance timing

margin and higher data rates in long and high-loading

networks. As designed, the device features cross-wire,

overvoltage, and loss of ground protection from −42 V to

+42 V, overtemperature shutdown, and a −30 V to +30

V common-mode range. The TPT1256 has a secondary

power supply input for I/O level shifting the input pin

thresholds and RXD output level. The device comes with

a silent mode which is also commonly referred to as listenonly mode, and it includes many protection features to

enhance device and network robustness.

The TPT125x is available in SOP-8 and DFN3X3-8L

packages and characterized from –40°C to +125°C.
