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.
The NCV7380 is a physical layer device designed for single-wire data links in automotive applications where high data rates are not required. It operates in systems developed for LIN 1.3 or LIN 2.0 and can also be used in ISO9141 systems. The device features very low current consumption in the recessive state, making it suitable for ECU applications without requiring sleep/wake-up control from a microprocessor.
Key characteristics include an operating voltage range of 6.0 to 18 V, integrated termination resistor for slave nodes, and protection against short circuits and transients. The IC includes slew rate control for improved EMC behavior and high signal symmetry for use in RC-based slave nodes.
| Operating Voltage (Battery Supply) | 6.0 to 18 V |
|---|---|
| Supply Current (Recessive) | Typ. 24 pA |
| Baud Rate | up to 20 kBaud |
| Operating Ambient Temperature | -40 to +125 °C |
| ESD Protection | +/- 4.0 kV |
The device works in systems designed for either LIN 1.3 or LIN 2.0 and can also be used in ISO9141 functions.
No additional termination resistor is necessary to use the NCV7380 on LIN slave nodes, as it has an integrated termination resistor.
The NCV7380 switches into thermal shutdown mode, turning off the bus driver while keeping the receiver on.
