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 in−vehicle
networking (IVN) transceiver family of ON Semiconductor that
integrates a LIN v2.1 physical transceiver and a low−drop 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 MCU−state 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.

♦ Undervoltage Detector with a Reset Output to the
Supplied Microcontroller
♦ INH Output for Auxiliary Purposes (switching of an
external pull−up or resistive divider towards battery,
control of an external voltage regulator etc.)
• Modes
♦ Normal Mode: LIN Communication in Either Low
(up to 10 kBaud) or Normal Slope
♦ Sleep Mode: V
CC
is Switched “off” and No
Communication on LIN Bus
♦ Standby Mode: V
CC
is Switched “on” but There is
No Communication on LIN Bus
♦ Wake−up Bringing the Component From Sleep
Mode Into Standby Mode is Possible Either by LIN
Command or Digital Input Signal on WAKE Pin
Wake−up from LIN Bus can also be Detected and
Flagged When the Chip is Already in Standby Mode

TYPICAL APPLICATION
Application Information
The EMC immunity of the Master−mode device can be
further enhanced by adding a capacitor between the LIN
output and ground. The optimum value of this capacitor is
determined by the length and capacitance of the LIN bus, the
number and capacitance of Slave devices, the pull−up
resistance of all devices (Master and Slave), and the required
time constant of the system, respectively.
V
CC
voltage must be properly stabilized by external
capacitors: capacitor of min. 80 nF (ESR < 10 mW) in
parallel with a capacitor of min. 8 mF (ESR < 1 W).
The 10 mF capacitor on the battery is optional and serves
as reservoir capacitor to deal with battery supply
micro−cuts.
