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
● ♦Indefinite Short−Circuit Protection on Pins LIN and
●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
