LINbus transceiver for 12V/24V automotive nodes
The Texas Instruments SN65HVDA100QDRQ1 is a single-wire LINbus transceiver designed for automotive body-control and sensor nodes. It handles half-duplex communication at 20kbps over a supply range of 5V to 27V, which covers both 12V and 24V battery systems without an external regulator.
Supply voltage: 5V to 27V — battery-direct connection
The 5V to 27V supply range is the standout feature for a LIN transceiver. It lets the part connect directly to a 12V or 24V vehicle battery without a pre-regulator, simplifying the BOM and reducing dropout concerns during cold-crank events. The 1/1 driver/receiver ratio is standard for a single LIN node.
