5Mbps, ±42V Fault Protected CAN Transceiver with CAN FD
The CA-IF1051AS/CA-IF1051AVS 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 ±42V fault protection on the CAN bus for equipment where overvoltage protection is required. These CAN devices also incorporate an input commonmode 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-IF1051AVS device, interfacing with CAN protocol controllers is simplified by the 3V 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-IF1051AS/CA-IF1051AVS are in a standard 8-pin SOIC package. Both parts operate over the -55°C to +150°C temperature range.
