Automotive CAN Transceivers with ±70V Fault Protection
Automotive CAN Transceivers with ±70V Fault Protection

Product Details

General Description

The CA-IF1042x devices are control 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 ±70V extended fault protection on the CAN bus for equipment where overvoltage protection is required. This family of CAN transceivers also incorporate an input common-mode range(CMR) of ±30V, exceeding the ISO 11898 specification of -2V to +7V, well suited for applications where ground planes from different systems are shifting relative to each other.

The CA-IF1042x 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 a STB pin for two modes of operation: normal high-speed mode and standby mode for low current consumption. Also, the CA-IF1042Vx family of devices provides low level translation to simplify the interface with low voltage CAN controllers.

The CA-IF1042x family of devices is available in a standard 8-pin narrow-body SOIC package and 8-pin DFN package, operates over the -55°C to +150°C junction temperature range.

Meets the ISO 11898-2:2016 and ISO 11898-5:2007 physical layer standards
