Active
Automotive LIN Transceiver
The CA-IF1022 is a Local Interconnect Network (LIN) dual channel transceiver, which is a low speed Universal Asynchronous Transceiver (UART) communication protocol that supports automotive in vehicle networks. The CA-IF1022 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-IF1022 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-IF1022 also supports low-power sleep mode.
