Product Details

General Description

The CA-IF1044x-Q1 high-speed control area network (CAN) transceivers meet the ISO 11898-2 physical layer standards. This family of devices is designed for using in automotive CAN FD networks up to 5 Mbps data rate and features ±58V extended fault protection on the CAN bus for equipment where overvoltage protection is required. The transceivers include a dominant timeout detection to prevent bus lockup caused by hung-up microcontroller, and the outputs CANH and CANL are short-circuit current-limited and protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs in a high-impedance state. Also, the CA-IF1044Vx-Q1 provides low level translation to simplify the interface with low voltage CAN controllers.

The CA-IF1044x-Q1 devices are in a standard 8-pin SOIC package and small-size 8-pin DFN package. This family of devices operates over the -40°C to +125°C temperature range.
