Product Details

General Description

The CA-IF1021-Q1 device is Local Interconnect Network (LIN) transceiver with integrated protection for automotive applications. LIN is low-speed universal asynchronous receiver transmitter(UART) communication protocol used to support automotive networking. The CA-IF1021-Q1 transceiver controls the LIN bus state via the TXD input and reports the bus state on its open-drain output RXD. This device features slew-rate control and wave-shaping to reduce electromagnetic emissions (EME).

The CA-IS1021-Q1 is designed to support up to 12V applications with 5.5V to 27V wide input voltage operating range. Also, this device supports low-power sleep mode, as well as wake-up from low-power mode through LIN bus, or the WAKE_N pin, SLP_N pin. The CA-IS1021-Q1 allows battery power consumption reduction at system-level by selectively enabling the various power supplies that can be present on a node through the INH pin. The CA-IF1021-Q1 integrates ESD protection and fault protection which help to reduce external components in the applications. In the event of a ground shift or supply voltage disconnection, the device prevents back-feed current through LIN to the supply input.

The CA-IF1021-Q1 device is available in a standard 8-pin SOIC package and 8-pin DFN package, operates over the -40°C to +150°C junction temperature range.
