General Description

The CA-IF1043x devices are controlled area network (CAN)  transceivers with integrated protection for industrial and automotive applications. These devices are designed for using in CAN FD networks up to 5 Mbps and feature ±58V  extended fault protection on the CAN bus for equipment where overvoltage protection is required. This family of CAN  transceivers also incorporates an input common-mode range(CMR) of ±30V, exceeding the ISO 11898 specification,  well suited for applications where ground planes from different systems are shifting relative to each other. 

The CA-IF1043x series devices include a dominant timeout to prevent bus lockup caused by controller error or by a fault on the TXD input. When the TXD remains in the dominant state (low) for longer than tDOM, the driver is switched to the recessive state, releasing the bus and allowing other nodes to communicate. The transceivers feature standby (nSTB) and enable (EN) control pins for different modes of operation: normal operation and standby mode, silent mode, sleep mode for low current consumption, as well as wake-up capability over CAN bus or via the WAKE pin.  Inhibit output (INH) can be used to control one or more external voltage regulators presented on a node to reduce the battery power consumption at system level. Also, the  CA-IF1043x devices provide low-level translation to simplify the interface with low-voltage CAN controllers.
