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. The part is AEC-Q100 qualified and rated for a junction temperature range of -40°C to 150°C, making it suitable for under-hood and cabin-zone ECUs where ambient heat and thermal cycling are factors.
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.
Temperature grade and deployment environment
Rated for -40°C to 150°C junction temperature, the TJA1124BHG/0Z covers the full automotive temperature envelope including engine bay and exhaust-adjacent locations. 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. AEC-Q100 qualification means the part has passed the full suite of automotive stress tests — pre- and post-lockout — and carries the grade traceability that tier-one ECU programs require for PPAP submission.
Lifecycle and sourcing posture
ROHS3 compliant. No LTB risk for new designs.
