NCV7425
LIN Transceiver with
Voltage Regulator and
Reset Pin
General Description
The NCV7425 is a fully featured local interconnect network (LIN)
transceiver designed to interface between a LIN protocol controller
and the physical bus.
The NCV7425 LIN device is a member of the inâvehicle
networking (IVN) transceiver family of ON Semiconductor that
integrates a LIN v2.1 physical transceiver and a lowâdrop voltage
regulator.
The LIN bus is designed to communicate low rate data from control
devices such as door locks, mirrors, car seats, and sunroofs at the
lowest possible cost. The bus is designed to eliminate as much wiring
as possible and is implemented using a single wire in each node. Each
node has a slave MCUâstate machine that recognizes and translates
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
to passenger comfort.

ORDERING INFORMATION
⢠Modes
See detailed ordering and shipping information in the
package dimensions section on page 19 of this data sheet.
⦠Normal Mode: LIN Communication in Either Low
(up to 10 kBaud) or Normal Slope
⦠Sleep Mode: VCC is Switched âoffâ and No
Communication on LIN Bus
⦠Standby Mode: VCC is Switched âonâ but There is
No Communication on LIN Bus
⦠Wakeâup Bringing the Component From Sleep
Mode Into Standby Mode is Possible Either by LIN
Command or Digital Input Signal on WAKE Pin
Wakeâup from LIN Bus can also be Detected and
Flagged When the Chip is Already in Standby Mode
