Automotive LIN Transceiver

The CA-IF1024F-Q1 is a Local Interconnect Network (LIN) four channel transceiver, which is a low speed Universal Asynchronous Transceiver (UART) communication protocol that supports automotive in vehicle networks. The CA-IF1024F-Q1 transceiver controls the LIN bus state via the TXDx input and reports the bus state on output RXD between the protocol controller and physical LIN networks. These device features slew-rate control and wave-shaping to reach a very low level of electromagnetic emission (EME) within a broad frequency range.

The CA-IF1024F-Q1 devices are designed to support 12V automotive applications with 5V to 18V wide VBAT input voltage operating range and have up to ±42V fault protection on LIN bus, with integrated ESD protection, these devices help to reduce external components in the design. In addition, CA-IF1024F-Q1 also supports low-power sleep mode.
