Description
The NCV7321 is a fully featured local interconnect network (LIN) transceiver designed to interface between a LIN protocol controller and the physical bus. The transceiver is implemented in I3T technology enabling both high−voltage analog circuitry and digital functionality to co−exist on the same chip.
FEATUREs
•General
♦SOIC−8 Green package (Pb−Free)
•LIN−Bus Transceiver
♦LIN Compliant to Specification Revision 2.0 and 2.1 (Backwards Compatible to Version 1.3) and J2602
♦Bus Voltage 45 V
♦Transmission Rate 1 kbps to 20 kbps
•Protection
♦Thermal Shutdown

WAKE Towards Supply and Ground
♦Load Dump Protection (45 V)
♦Bus Pins Protected Against Transients in an
Automotive Environment
•EMI Compatibility
♦Integrated Slope Control
•Modes
♦Normal Mode: LIN Transceiver Enabled, Communication via the LIN Bus is Possible, INH Switch is On
♦Sleep Mode: LIN Transceiver Disabled, the Consumption from VBBis Minimized, INH Switch is Off
♦Standby Mode: transition mode reached either after power−up or after a wakeup event, INH switch is on
♦Wake−up Bringing the Component from Sleep Mode into Standby Mode is Possible either by LIN Command or a Digital Signal on WAKE Pin (e.g. External Switch)
•These are Pb−Free Devices
