7.3.12 Unpowered Device and LIN Bus

In automotive applications some LIN nodes in a system can be unpowered (ignition supplied) while others in the network remains powered by the battery. The TLIN1022-Q1 has a low unpowered leakage current from the bus so an unpowered node does not affect the network or load it down.
