Quad LIN transceiver for automotive body electronics
The NXP TJA1124BHG/0Z is a quad-channel LIN transceiver in a 24-DHVQFN (5.5x3.5) package, designed for automotive body-control and sensor networks. It integrates four drivers and four receivers in a full-duplex configuration, supporting the LIN protocol at 20 kBd.
Supply range and power architecture fit
The transceiver operates from a 5V to 28V supply, covering both nominal 12V battery and 24V truck electrical systems.
The 150°C TJ ceiling is the key number for thermal derating: if the ECU sits near a hot manifold or in a sealed enclosure with limited airflow, the junction temperature budget must be checked against the actual power dissipation at the expected ambient.
ROHS3 compliant.
