NCV7382
Advance Information
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 wake−up function detects incoming
dominant bus messages and enables the voltage regulator.
Features
• Operating Voltage VS = 6.0 to 18 V
• Very Low Standby Current Consumption of Typ. 6.5 mA in Sleep
Mode
• LIN−Bus Transceiver:
♦ Slew Rate Control for Good EMC Behavior
♦ Fully Integrated Receiver Filter
♦ BUS Input Voltage −27 V to 40 V
♦ Integrated Termination Resistor for LIN Slave Nodes (30 kW)
♦ Wake−Up Via LIN Bus
♦ Baud Rate up to 20 kBaud
♦ Will Work in Systems Designed for Either LIN 1.3 or LIN 2.0
• Compatible to ISO9141 Functions
• High EMI Immunity
• Bus Terminals Protect Against Short−Circuits and Transients in the
Automotive Environment
• High Impedance Bus Pin for Loss of Ground and Undervoltage
Condition
• Thermal Overload Protection
• High Signal Symmetry for use in RC−Based Slave Nodes up to 2%
Clock Tolerance when Compared to the Master Node
• "4.0 kV ESD Protection on BUS, VS and INH Pins
• Control Output for Voltage Regulator with Low On−Resistance for
Switchable Master Termination
• NCV Prefix for Automotive and Other Applications Requiring Site
and Change Control
