IFX1021SJ

The IFX1021SJ is a transceiver for the Local Interconnect Network (LIN) with integrated Wake-Up and protection features. It is designed for data transmission rates from 2.4 kBaud to 20 kBaud. The IFX1021SJ serves as a bus driver between the protocol controller and the physical bus inside the LIN network. The IFX1021SJ is compliant to all LIN standards and offers a wide operational supply range up to 40V. Different operation modes and the INH output allow the IFX1021SJ to control external components like e.g. voltage regulators. In Sleep-mode the IFX1021SJ draws less than 8 μA of quiescent current while still being capable of “wake up” by LIN bus traffic and a local Wake-Up input. The very low leakage current on the BUS pin makes the IFX1021SJ especially suitable for partially supplied networks and supports the low quiescent current requirements of the LIN network.
