Unlock complex network topologies with CAN signal improvement capability

Increase speed without sacrificing data reliability with our CAN signal improvement capability transceivers, allowing data rates up to 8Mbps. These devices eliminate ringing at the dominant-to-recessive edge of CAN transmission, ensuring signal reliability in complex network topologies.

CAN FD signal improvement capability devices are drop-in compatible to our non-signal improvement capability 5V CAN transceivers, allowing designers to upgrade existing topologies instead of designing a new network. These devices are fully compatible to current International Organization for Standardization 11898-2:2024 standards and backward-compatible to CAN in Automation 601-4, classical CAN and CAN FD specifications.

Optimize power consumption with targeted wakeup of CAN nodes

Our CAN transceivers with partial networking conserve power by enabling targeted wakeup of individual transceivers based on programmable wake-up patterns. This functionality keeps a reduced number of CAN nodes in an active state and the remaining nodes in a low-power state. The TCAN1146-Q1 and TCAN1576-Q1 include bus fault diagnostics and watchdog timers, making your system safer and more reliable.

These devices feature both standard CAN and CAN signal improvement capability options and can be used with other types of CAN transceivers, enabling flexibility and power savings only in certain nodes.
