Isolated CAN transceiver brand

Zhiyuan Electronics released the first isolated CAN transceiver in China in 2003, and has accumulated CAN bus isolation technology for nearly 20 years. At present, CTM series isolated transceivers cover all CAN-bus communication protocols such as CAN2.0A, CAN2.0B and CAN FD, and they are the leading brands of isolated CAN transceivers in China.

Isolated CAN transceiver brand

High static electricity and surge protection level

CTM1051 (A) HP integrates a highly reliable surge protection circuit. The immunity to electrostatic discharge is up to 8kV, and the immunity to lightning surge is up to 4kV. The product can effectively solve the abnormal communication problems caused by electrostatic and surge interference in industrial field, and it is widely applied in motors, electric power and other industries.

Support CAN FD protocol bus isolation

With the rapid development of automobile electronics and industrial automation, the number of devices and data on the CAN bus has greatly increased, which brings great challenges to the CAN bus. In order to meet the requirements of high bandwidth and data throughput, the high-speed CAN protocol-CAN FD was produced. Zhiyuan Electronics has launched CTM1051AMG, a CAN FD isolation transceiver with good performance and high speed. It is small in size (board occupying area: only 12.8mm*7.7mm) and supports the transmission rate up to 5Mbps. It is an ideal solution for CAN FD isolation application.
