What this LIN transceiver does and where it fits
The Texas Instruments TLIN2022ADMTRQ1 is an automotive-grade LIN transceiver in a half-duplex 2/2 driver/receiver configuration. It handles the physical layer for LIN 2.x compliant networks, converting the digital LIN bus signal to a single-wire 12V or 24V bus.
Supply voltage range — 4V to 48V
The supply range of 4V to 48V covers 12V and 24V vehicle architectures with generous headroom for load-dump transients. In a 12V system the transceiver operates directly from the battery rail without a preregulator; in a 24V truck or bus the same part works without derating. The 48V upper limit also accommodates mild-hybrid 48V boards. For the BOM this means one LIN transceiver line item across multiple vehicle platforms, simplifying qualification and inventory.
Temperature grade and automotive qualification
Rated for -40°C to 125°C ambient, this part covers under-hood, engine-bay, and cabin deployments. The AEC-Q100 qualification means the part has passed the automotive stress tests for high-temperature operating life, temperature cycling, and ESD robustness. For a procurement decision this is the gate: if the BOM requires AEC-Q100, the TLIN2022ADMTRQ1 meets it; if not, a commercial-grade LIN transceiver may be cheaper, but the qualification is the reason this part is specified in automotive ECU designs.
