1. General description
The TJA1022 is a dual LIN transceiver that provides the interface between a Local
Interconnect Network (LIN) master/slave protocol controller and the physical bus in a LIN
network. It is primarily intended for in-vehicle subnetworks using baud rates up to 20 kBd
and is compliant with LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and SAE J2602. The TJA1022 is
pin compatible with th e TJA1020, TJA10 21 and TJA102 7 ( see Section 18). The TJA1022
and TJA1027 are also software compatible.
The transmit data streams generated by the protocol controller are converted by the
TJA1022 into optimized bus signals shaped to minimize ElectroMagnetic Emissions
(EME). The LIN bus output pins are pulled HIGH via internal termination resistors. For a
master application, an external resistor in series with a diode should be connected
between pin VBAT and each of the LIN pin s. The re ceivers dete ct receive da ta streams on
the LIN bus input pins and transfer them via pins RXD1 and RXD2 to the microcontroller.
Power consumption is very low when both transceivers are in Sleep mode. However, the
TJA1022 can still be woken up via pins LIN1/LIN2 and SLP1_N/SLP2_N.

Dual LIN 2.2A/SAE J2602 transceiver
7. Functional description
The TJA1022 is the int er fa ce be tw ee n th e LI N mas te r/s lave protocol con trolle r an d the
physical bus in a LIN net wor k. Accor din g to the Open System Interconnect (OSI) model,
this is the LIN physical layer.
The LIN transceivers are optimized for, but not limited to, automotive applications with
excellent ElectroMagnetic Compatibility (EMC) performance.
7.1 LIN 2.x/SAE J2602 compliant
The TJA1022 is fully LIN 2.0, LIN 2.1, LIN 2.2, LIN 2.2A and SAE J2602 compliant. The
LIN physical layer is independent of higher OSI model layers (e.g. the LIN protocol).
Consequently, nodes containing a LIN 2.2A-compliant physical layer can be combined,
without restriction, with LIN physical layer nodes that comply with earlier revisions
(LIN 1.0, LIN 1.1, LIN 1.2, LIN 1.3, LIN 2.0, LIN 2.1 and LIN 2.2).
7.2 Operati ng modes
The transceivers are fully operational in Normal mode. A low-power Sleep mode is also
supported, as well as a Reset mode. Standby mode facilitates the transition between
Sleep and Normal modes.
The transceivers operate independently (except in Reset mode), so one transceiver can
be in Normal mode while the other is Sleep or Standby etc. Power consumption is at a
minimum when both transceivers are in Sleep mode.
7.2.1 Normal mode
In Normal mode, the TJA1022 can transmit and receive data via the LIN bus lines. The
transceivers operate independently, so one can be active while the other is off.
A transceiver will switch from Sleep or Standby mode to Normal mode if SLPx_N is held
HIGH for tgotonorm. If SLPx_N is held LOW for tgotosleep, the transceiver will switch from
Normal to Sleep mode.
The receivers detect data streams on the LIN bus lines (via pins LIN1 and LIN2) and
transfer the input via pins RXD1 and RXD2 to the microcontroller (see Figure 6): HIGH for
a recessive level and LOW for a dominant level on the bus. The receivers have
supply-voltage related thresholds with hysteresis and integrated filters to suppress bus
line noise.
T ransmit data streams from the protocol controller are detected on the TXDx pins and are
converted by the transmitters into optimized bus signals shaped to minimize EME. The
LIN bus output pins are pulled HIGH via internal slave termination resistors. For a master
application, an external resistor in series with a diode should be connected between pin
VBAT and the appropriate LINx pin (see Figure 6).

Product data sheet Rev. 2 — 24 April 2013 6 of 26
NXP Semiconductors TJA1022
Dual LIN 2.2A/SAE J2602 transceiver
7.2.2 Sleep mode
A transceiver will switch to Sleep mode from Normal mode if SLPx_N is held LOW for
tgotosleep. The relevant LIN transmit path is disabled as soon as SLPx_N goes LOW.
Power consumption is very low when both transceivers are in Sleep mode.
The volt age levels on LINx and TXDx have no ef fect on a transition to Sleep mode. So the
transceiver will still switch to Sleep mode even if TXDx is held LOW or there is a
continuous dominant level on LINx (e.g. due to a short circuit to ground).
Although current consumption is extremely low when both transceivers are in Sleep
mode, the TJA1022 can still be woken up remotely via the LIN bus pins or by the
microcontroller via pins SLPx_N. Filters on the receiver inputs (LIN1 and LIN 2) and on
pins SLPx_N prevent unwanted wake-up events occurring due to automotive transients or
radio frequency interference. To be valid, all wake-up events must be maintained for a
specific length of time (twake(dom)LIN for a remote wake-up and tgotonorm for a wake-up via
SLPx_N). Pin RXDx is floating when a transceiver is in Sleep mode.
(1) A positive edge on SLPx_N triggers a transition to Normal mode in the corresponding LIN transceiver; the LIN transmitter is
enabled once TXDx goes HIGH; in the event of thermal shutdown, both LIN transceivers are disabled.
(2) Power dissipation is at a minimum when both transceivers are in Sleep mode.
(3) When a transceiver switches to Standby mode in response to a LIN bus wake-up event, the associated RXDx pin (RXD1 or
RXD2) will be LOW to indicate which LIN channel was the source of the wake-up request.

NXP Semiconductors TJA1022
Dual LIN 2.2A/SAE J2602 transceiver
If a remote wake-up event (see Figure 4) is detected on either of the LIN bus lines, the
associated transceiver will switch to Standby mode. A wake-up initiated by the
microcontroller (SLPx_N HIGH for t gotonorm) will cause the relevant transceiver to switch to
Normal mode while the other transceiver remains in its current state.
7.2.3 Standby mode
Standby mode is a n interme diate mode be twee n Slee p and Nor ma l mod es. A transceiver
will switch from Sleep mode to Standby mode in response to a LIN bus wake-up event.
Pin RXDx will go low to indicate to the microcontroller the source of the remote wake-up
(LIN1 or LIN2). A transceiver will switch from Standby to Normal mode if the
microcontroller holds SLPx_N HIGH for tgotonorm.
7.2.4 Reset mode
When the TJA1022 is in Reset mode, all input signals are ignored and all output drivers
are off. The TJA1022 switches to Reset mode when the voltage on VBAT drops below the
LOW-leve l power-on reset threshold, V th(POR)L. When the vo ltag e on VBAT rises above the
HIGH-level power-on reset threshold, Vth(POR)H, the transceivers switch to Sleep mode.
[1] Both transceivers enter Sleep mode after a power-on reset (e.g. after switching on VBAT).
[2] The appropriate transceiver will switch automatically to Standby x mode if a remote LINx wake-up event is
detected in Sleep x mode.
[3] RXDx will be LOW to indicate the source of the remote wake-up request; RXDx will go HIGH in response to
a positive edge on pin SLPx_N.
[4] A positive edge on SLPx_N will trigger a transition to Normal mode; the transmitter will be off if TXDx is
LOW and will be enabled as soon as TXDx goes HIGH.

7.3 Transceiver wake-up
7.3.1 Remote wake-up via the LIN bus
A falling edge on pin LINx followed by a LOW level main tained for twake(dom)LIN followed by
a rising edge on pin LINx triggers a remote wake-up (see Figure 4). It should be noted that
the time period twake(dom)LIN is measured either in Nor mal mode while TXDx is HIGH, or in
Sleep mode irrespective of the status of pin TXDx.
7.3.2 Wake-up via SLPx_N
If SLPx_N is held HIGH for tgotonorm, the transceiver will switch from Sleep mode to
Normal mode.
7.4 Operation during automotive cranking pulses
TJA1022 remains fully operational during automotive cranking pulses because the LIN
transceivers are fully specified down to VBAT = 5 V.
7.5 Operation when supply voltage is outside specified operating range
If VBAT > 18 V or VBAT < 5 V, the TJA1022 may remain operational, but parameter values
cannot be guaranteed to remain within the operating ranges specified in Table 7 and
Table 8.
In Normal mode:
If the input level on pin TXDx is HIGH, the LIN transmitter output on pin LINx will be
recessive.
If the input level on pin LINx is recessive, the receiver output on pin RXDx will be
HIGH.
If the voltage on pin VBAT rises to 27 V (e.g. during an automotive jump-start), the total
LIN network pull-up resist ance should be gre ater than 680 and the total LIN network
capacitance should be less than 6.8 nF to ensure reliable LIN data transfer.
If the voltage on pin V BAT drops below the LOW -level VBAT LOW threshold, Vth(VBATL)L,
the active LIN transmit path(s) is interrupted and both LIN outputs will be recessive.
The previously active LIN transmit path(s) is switched on again when VBAT rises
above Vth(VBATL)H and the associated TXDx pin is HIGH.

NXP Semiconductors TJA1022
Dual LIN 2.2A/SAE J2602 transceiver
If the voltage on pin VBAT drops below the LOW-level power-on reset threshold, Vth(POR)L,
the TJA1022 switches to Reset mode (i.e. all output drivers are disabled an d all inputs are
ignored). The TJA1022 switches to Sleep mode if VBAT > Vth(POR)H.
7.6 Fail-safe features
Pin TXDx is pulled down to ground in order to force a predefined level on the transmit dat a
input if the pin is disconnected.
Pin SLPx_N is pulled down to ground to ensure the tran scei ver is fo rced to Sleep x mode
if SLPx_N is disconnected.
Pins RXD1 and RXD2 are set floating if VBAT is disconnected.
The current in the transmitter output stage is limited in order to protect the transmitter
against short circuits to pins VBAT or GND.
A loss of power (pins VBAT and GND) has no impact on the bus lines or on the
microcontroller. No reverse current will flow from the bus lines into the LINx pins. The
current path from VBAT to LINx via the integrated LIN slave termination resistors remains.
The TJA1022 can be disconnected from the power supply without influencing the LIN
busses.
The output drivers on pins LIN1 and LIN2 are protected against ove rtemperature
conditions. If the junction temperature exceeds the shutdown junction temperature, Tj(sd),
the thermal prote ct i on circu it disa b les th e ou tp ut drive rs . Th e dr ive rs ar e ena ble d ag a in
when the junction temperature falls below Tj(sd) and pin TXDx is HIGH.
The initial TXD dominant check prevents the bus being driven to a permanent dominant
state (blocking all network communications) if pin TXDx is forced permanently LOW by a
hardware and/or software application failure. The input level on TXDx is checked after a
transition to Normal mode. If TXDx is LOW, the transmit path will remain disabled and will
only be enabled when TXDx goes HIGH.
Once the transmitter has been enabled, a TXD dominant time-out timer is started every
time pin TXDx goes LOW. If the LOW state on pin TXDx pe rsists for longer than the
TXD dominant time-out time (tto(dom)TXD), the transmitter is disabled, releasing the bus
line to recessive state. The TXD dominant time-out timer is reset when pin TXDx goes
HIGH.

15. Handling information
All input and output pins are protected against ElectroStatic Discharge (ESD) under
normal handling. When handling ensure that the appropriate prec a ut io ns ar e taken as
described in JESD625-A or equivalent standards.
16. Soldering of SMD packages
This text provides a very brief insight into a complex technology. A more in-depth account
of soldering ICs can be found in Application Note AN10365 “Surface mount reflow
soldering description”.
16.1 Introduction to soldering
Soldering is one of the most common methods through which packages are attached to
Printed Circuit Boards (PCBs), to form electrical circuits. The soldered joint provides both
the mechanical and the electrical connection. There is no single soldering method that is
ideal for all IC packages. Wave soldering is often preferred when through-hole and
Surface Mount Devices (SMDs) are mixed on one printed wiring board; however, it is not
suitable for fine pitch SMDs. Reflow soldering is ideal for the small pitches and high
densities that come with increased miniaturization.
16.2 Wave and reflow soldering
W ave soldering is a joinin g technology in which the joint s are made by solder coming from
a standing wave of liquid solder. The wave soldering process is suitable for the following:
Through-hole components
Leaded or leadless SMDs, which are glued to the surface of the printed circuit board
Not all SMDs can be wave soldered. Packages with solder balls, and some leadless
packages which have solder lands underneath the body, cannot be wave soldered. Also,
leaded SMDs with leads having a pitch smaller than ~0.6 mm cannot be wave soldered,
due to an increased probability of bridging.
The reflow soldering process involves applying solder paste to a board, followed by
component placement and exposure to a temperature profile. Leaded packages,
packages with solder balls, and leadless packages are all reflow solderable.
Key characteristics in both wave and reflow soldering are:
Board specifications, including the board finish, solder masks and vias
Package footprints, including solder thieves and orientation
The moisture sensitivity level of the packages
Package placement
Inspection and repair
Lead-free soldering versus SnPb soldering
16.3 Wave soldering
Key characteristics in wave soldering are:

Product data sheet Rev. 2 — 24 April 2013 20 of 26
NXP Semiconductors TJA1022
Dual LIN 2.2A/SAE J2602 transceiver
Process issues, such as application of adhesive and flux, clinching of leads, board
transport, the solder wave parameters, and the time during which components are
exposed to the wave
Solder bath specifications, including temperature and impurities
16.4 Reflow soldering
Key characteristics in reflow soldering are:
Lead-free ve rsus SnPb soldering; note th at a lead-free reflow process usua lly leads to
higher minimum peak temperatures (see Figure 9) than a SnPb process, thus
reducing the process window
Solder paste printing issues including smearing, release, and adjusting the process
window for a mix of large and small components on one board
Reflow temperature profile; this profile includes preheat, reflow (in which the board is
heated to the peak temperature) and cooling down. It is imperative that the peak
temperature is high enoug h for the solder to make reliable solder joint s (a solder paste
characteristic). In addition, the peak temperature must be low enough that the
packages and/or boards are not damaged. The peak temperature of the package
depends on package thickness and volume and is classified in acco rdance with
Table 10 and 11
Moisture sensitivity precautions, as indicated on the packing, must be respected at all
times.
Studies have shown that small packages reach hig her temperatures duri ng reflow
soldering, see Figure 9.

The TJA1022 pin layou t has been de signed to be comp a tible with the TJA102 0, TJA1021
and TJA1027. This makes it possible to design a board with a single socket that can
accommodate all four IC’s. The appropriate device would be inserted into the socket,
depending on the application, as illustrated in Figure 10.
