Chipanalog CA-IF1021D-Q1

The CA-IF1021x-Q1 family of device is Local Interconnect Network (LIN) transceiver with integrated wake-up and protection features for automotive applications. LIN is low-speed universal asynchronous receiver transmitter (UART) communication protocol used to support in-vehicle networks. The CA-IF1021x-Q1 transceiver controls the LIN bus state via the TXD input and reports the bus state on its open-drain 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-IS1021x-Q1 devices are designed to support 12V automotive applications with 5.5V to 27V wide VBAT input voltage operating range and have up to ±58 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 WAKE_N pin, SLP_N pin. Inhibit output (INH) can be used to control one or more external voltage regulators presented on a node to reduce the battery power consumption at system level. In the event of a ground shift or supply voltage disconnection, the devices can prevent back-feed current through LIN to the supply input. The CA-IF1021x-Q1 transceiver is available in a standard 8-pin SOIC package and 8-pm DFN package, operates over the -40℃ to +150℃ junction temperature range.
