The CA-IF1028 family of device is Local Interconnect Network (LIN) transceiver with integrated wake-up and protection features for automotive applications. LIN is lowspeed universal asynchronous receiver transmitter (UART) communication protocol used to support in-vehicle networks. The CA-IF1028 transceiver controls the LIN bus state via the TXD 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.

CA-IF1028 devices are designed to support 12V automotive applications with 5.5V to 28V 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.

Also, these devices feature low-power Sleep mode, as well as wake-up capability over LIN bus, or via the EN pin. In the event of a ground shift or supply voltage disconnection, the devices can prevent back-feed current through LIN to V_BAT.

CA-IF1028 integrates a low dropout regulator (LDO), providing 5V or 3.3V voltage output, with power supply currents up to 100mA (SOIC8) and 125 mA (DFN8) to power other devices.
