NCV7425 LIN Transceiver with Voltage Regulator and Reset Pin General Description www.onsemi.com The NCV7425 is a fully featured local interconnect network (LIN) transceiver designed to interface between a LIN protocol controller MARKING and the physical bus. DIAGRAM 16 The NCV7425 LIN device is a member of the invehicle networking (IVN) transceiver family of ON Semiconductor that SOIC16 LEAD integrates a LIN v2.1 physical transceiver and a lowdrop voltage NCV7425x WIDE BODY AWLYYWWG regulator. EXPOSED PAD 16 The LIN bus is designed to communicate low rate data from control CASE 751AG 1 devices such as door locks, mirrors, car seats, and sunroofs at the 1 lowest possible cost. The bus is designed to eliminate as much wiring x = 0 or 5 as possible and is implemented using a single wire in each node. Each A = Assembly Location WL = Wafer Lot node has a slave MCUstate machine that recognizes and translates YY = Year the instructions specific to that function. The main attraction of the WW = Work Week LIN bus is that all the functions are not time critical and usually relate G = PbFree Package to passenger comfort. ORDERING INFORMATION Features See detailed ordering and shipping information in the LINBus Transceiver package dimensions section on page 19 of this data sheet.

The applied transients shall be in accordance with ISO 7637 part 1, test pulse 5. The device complies with functional class C . The LIN communication itself complies with functional class B. On regulator class A can be reached depending on the application and external components 2. V voltage must be properly stabilized by external capacitors: capacitor of min. 80 nF with ESR < 10 m in parallel with a capacitor of min. CC 8 F, ESR < 1 . Table 2.
