5Mbps, ±58V Fault Protected CAN Transceiver with CAN FD

Product Details

General Description

The CA-IF1051S/CA-IF1051VS are control area network (CAN) transceivers with integrated protection for industrial applications. This family of devices is designed for using in high-speed CAN FD networks up to 5Mbps data rate, features extended ±58V fault protection on the CAN bus for equipment where overvoltage protection is required. These CAN devices also incorporate 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. For the CA-IF1051VS device, interfacing with CAN protocol controllers is simplified by the 2.5V to 5.5V wide logic-supply voltage range (VIO).

The transmitter include a dominant timeout detection 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 family of devices features a silent-mode option to disable the transmitter.

The CA-IF1051S/CA-IF1051VS are in a standard 8-pin SOIC package. Both parts operate over the -55°C to +150°C temperature range.

Meets the ISO 11898-2:2016 and ISO 11898-5:2007 Physical Layer Standards
