IFX1040: New Industrial-Grade, High-Speed CAN Transceiver with Stand-By Mode and Bus Wake-Up

Infineon IFX1040SJ

The Infineon's CAN transceiver IFX1040SJ is a monolithic integrated circuit in a PG-DSO-8 package for high-speed differential mode data transmission (up to 1Mbaud) and reception in industrial applications.

IFX1040SJ serves as an interface between the CAN protocol controller and physical bus lines compatible with the ISO/DIS 11898 standard.

The transceiver delivers excellent passive behavior when it is switched off and supports remote wake-up capability via CAN bus in low-power mode, making it ideal for networks with partially un-powered nodes in energy-efficient industrial-grade system designs.
