The NCV7382 is a physical layer device for a single wire data link capable of operating in applications where high data rate is not required and a lower data rate can achieve cost reductions in both the physical media components and in the microprocessor which uses the network. The NCV7382 is designed to work in systems developed for LIN 1.3 or LIN 2.0. The IC furthermore can be used in ISO9141 systems. Because of the very low current consumption of the NCV7382 in the sleep mode it’s suitable for ECU applications with low standby current requirements. This mode allows a shutdown of the whole application. The included wakeup function detects incoming dominant bus messages and enables the voltage regulator.
