1. VS is the IC supply voltage including voltage drop of reverse battery protection diode, VDROP = 0.4 to 1.0 V, VBAT_ECU voltage range is 7.0 to 18 V.
2. ISO 7637 test pulses are applied to VS via a reverse polarity diode and > 2.0 F blocking capacitor.
3. ISO 7637 test pulses are applied to BUS via a coupling capacitance of 1.0 nF.

The NCV7380 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 NCV7380 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 NCV7380 in recessive state, it's suitable for ECU applications with low standby current requirements, whereby no sleep/wake−up control from the microprocessor is necessary.
