±70V Fault Protected CAN Transceiver with CAN FD
±70V Fault Protected CAN Transceiver with CAN FD

Product Details

General Description

CA-IF1051H is +5V control area network (CAN) transceivers with integrated protection for industrial applications. This device is designed for using in CAN FD networks up to 5 Mbps and features extended ±70V fault protection on the CAN bus for equipment where overvoltage protection is required. This CAN device also incorporates an input common-mode range (CMR) of ±30V, exceeding the ISO 11898 specification of -2V to +7V, and well suited for applications where ground planes from different systems are shifting relative to each other.

The transceivers include a dominant timeout to prevent bus lockup caused by controller error or by a fault on the TXD input. When TXD remains in the dominant state (low) for longer than tDOM, the driver is switched to the recessive state, releasing the bus. In addition, this device comes with silent mode which is also commonly referred to as listen-only mode.

The CA-IF1051H is in a standard 8-pin narrow-body SOIC package and 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
