NCV7321 Stand-alone LIN Transceiver 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 highvoltage analog circuitry and digital www.onsemi.com functionality to coexist on the same chip. The NCV7321 LIN device is a member of the invehicle MARKING networking (IVN) transceiver family. DIAGRAMS The LIN bus is designed to communicate low rate data from control 8 devices such as door locks, mirrors, car seats, and sunroofs at the NV7321x SOIC8 lowest possible cost. The bus is designed to eliminate as much wiring 8 FALYW CASE 751 as possible and is implemented using a single wire in each node. Each 1 node has a slave MCUstate machine that recognizes and translates 1 the instructions specific to that function. The main attraction of the LIN bus is that all the functions are not time critical and usually relate 1 NV73 to passenger comfort.

Extended exposure to stresses beyond the Recommended Operating Ranges limits may affect device reliability. 1. Below 5 V on V in normal mode, the bus will either stay recessive or comply with the voltage level specifications and transition time BB specifications as required by SAE J2602. It is ensured by the battery monitoring circuit. Above 27 V on V , LIN communication is operational BB (LIN pin toggling) but parameters cannot be guaranteed. For higher battery voltage operation above 27 V, LIN pullup resistor must be selected large enough to avoid clamping of LIN pin by voltage drop over external pullup resistor and LIN pin min current limitation. 2. Equivalent to discharging a 100 pF capacitor through a 1.5 k resistor conform to MIL STD 883 method 3015.7. 3. Equivalent to discharging a 150 pF capacitor through a 330 resistor. System HBM levels are verified by an external testhouse. 4. Direct Capacitor Coupling (DCC) method according to SAE J29621 specification, referring to ISO 76373 Slow Transient Pulse. Coupling Capacitor 10 nF. Tested with no external protections. Verified by an external test house. Table 2.
