EMC神器，无需共模电感！替代TJA1040T，TJA1050T，TJA1051T，PCA82C250 最新Mantis系列

Overview

The TJA1057 is part of the Mantis family of high-speed CAN transceivers. It provides an interface between a Controller Area Network CAN protocol controller and the physical two-wire CAN bus. The transceiver is designed for high-speed CAN applications in the automotive industry, providing the differential transmit and receive capability to a microcontroller with a CAN protocol controller.

The TJA1057 offers a feature set optimized for 12 V automotive applications, with significant improvements over first- and second-generation CAN transceivers from , such as the TJA1050, and excellent ElectroMagnetic Compatibility EMC performance.

The TJA1057 also displays ideal passive behavior to the CAN bus when the supply voltage is off.

A VIO pin on the TJA1057GTK/3 variants allows for direct interfacing with 3.3 V and 5 V-supplied microcontrollers.

The TJA1057 implements the CAN physical layer as defined in the current ISO11898-2:2003 standard and the pending updated version of ISO11898-2:2016. The TJA1057T variant is specified for data rates up to 1 Mbit/s. Pending the release of ISO11898-2:2016 including CAN FD and SAE-J2284-4/5, additional timing parameters are specified for the TJA1057GT/3 and TJA1057GTK/3 variants. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.

These features make the TJA1057 an excellent choice for HS-CAN networks that only require basic CAN functionality.
