NCV7382
Enhanced LIN Transceiver
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.
