SJA1124BHG/1Z

SJA1124BHG/1Z is a quad local interconnect network (LIN) transceiver with LIN commander controller. Each of the four channels contains a LIN commander controller and LIN transceiver with commander termination. LIN commander frames are transferred to the physical LIN bus via the LIN physical layer. This is primarily intended for in-vehicle subnetworks using baud rates up to 20KBd and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A, ISO 17987-4:2016 and SAE J2602-1. A Serial Peripheral Interface and an interrupt output provide the interface between the SJA1124 and a microcontroller. Transmit data streams received on the SPI are converted into LIN commander frames transmitted on the LIN bus. The LIN commander frames are transmitted as optimized bus signals shaped to minimize Electromagnetic Emission. Data streams received on the LIN bus input pins can be read by the microcontroller via the SPI.

• Four LIN commander channels, LIN commander controller, LIN transceiver
• Very low current consumption in Low Power mode with wake-up via SPI or LIN
• Option to control an external voltage regulator via the INHN output
• Bus signal shaping optimized for baud rates up to 20KBd
• Interrupt output pin: interrupts can be configured individually
• VIO input for direct interfacing with 3.3V and 5V microcontrollers
• On-chip phase-locked loop (PLL) for LIN commander controller
• Passive behaviour in unpowered state, under voltage detection
• Independent per LIN channel baud rate, operating mode, status and interrupt
• DHVQFN24 package, virtual junction temperature range from -40 to 150°C
