FUNCTIONAL DESCRIPTION

The TJA1053 is the interface between the CAN protocol
controller and the physical bus. It is primarily intended for
low speed applications, up to 125 kBaud, in passenger
cars. The device provides differential transmit capability to
the bus and differential receive capability to the CAN
controller.

To reduce RF interference the rise and fall slope are
limited. This allows the use of an unshielded twisted pair or
a parallel pair of wires for the bus. Moreover, it supports
transmission capability on either bus wire if one of the bus
wires is corrupted. The failure detection logic automatically
selects a suitable transmission mode.

In normal operation (no wiring failures) the differential
receiver is output to RXD. The differential receiver inputs
are connected to CANH and CANL through integrated
filters. The filtered input signals are also used for the single
wire receivers. The CANH and CANL receivers have
threshold voltages that ensure a maximum noise margin in
single-wire modes.

A timer has been integrated at the TXD input. This timer
prevents the TJA1053 to drive the bus lines to permanent
dominant state.

Failure detector

This time is needed to avoid false triggering by external RF
fields. Recovery from these failures is detected
automatically after a certain time-out (filtering) and no
transmission is lost. The CANH driver and the RTH pin are
switched off in the event of failure 3.

Failures 4 and 7 initially result in a permanent dominant
level at RXD. After a time-out, the CANL driver and the
RTL pin are switched off. Only a weak pull-up at RTL
remains. Reception continues by switching to the
single-wire mode via CANH. When failures 4 or 7 are
removed, the recessive bus levels are restored. If the
differential voltage remains below the recessive threshold
level for a certain period of time, reception and
transmission switch back to the differential mode.

If any of the seven wiring failures occur, the output NERR
will be made LOW. On error recovery, NERR will be made
HIGH again.

During all single-wire transmissions, the EMC
performance (both immunity and emission) is worse than
in the differential mode. Integrated receiver filters
suppress any HF noise induced into the bus wires.
The cut-off frequency of these filters is a compromise
between propagation delay and HF suppression. In the
single-wire mode, low frequency noise cannot be
distinguished from the required signal.

The failure detector is active in the normal operation mode
and detects the following single bus failures and switches
to an appropriate mode:

1. CANH wire interrupted

2. CANL wire interrupted

3. CANH short-circuited to battery

4. CANL short-circuited to ground

5. CANH short-circuited to ground

6. CANL short-circuited to battery

7. CANL mutually shorted to CANH.
The differential receiver threshold is set at −2.9 V.

This ensures correct reception in the normal operating
modes and, in the event of failures 1, 2 and 5 with a noise
margin as high as possible. These failures, or recovery
from them, do not destroy ongoing transmissions.

Failures 3 and 6 are detected by comparators connected
to CANH and CANL, respectively. If the comparator
threshold is exceeded for a certain period of time, the
reception is switched to the single-wire mode.

Low power modes

The transceiver provides 3 low power modes which can be
entered and exited via pins

STB and EN (see Table 1).

The sleep mode is the mode with the lowest power
consumption. The INH pin is switched to high-impedance
for deactivation of external voltage regulators. CANL is
biased to the battery voltage via the RTL output. If the
supply voltage is provided the RXD and NERR will signal
the wake-up interrupt

The V

standby mode will react the same as the sleep

BAT

mode with an active INH output.
The VCC standby mode is the V

standby with RTL

BAT

switched to the VCC voltage. In this mode the NERR output
signals the V

power-on flag and the RXD output will

BAT

show the wake-up interrupt.

1997 Oct 15 5

Philips Semiconductors Preliminary specification

Fault-tolerant CAN transceiver TJA1053

Wake-up requests are recognized by the transceiver when
a dominant signal is detected on either bus line or if the
WAKE pin is connected to ground. On a wake-up request
the transceiver will set the INH output which can be used
to activate the external VCC voltage regulator. If VCC is
provided the wake-up request can be read on the NERR or
RXD outputs, on which the external microcontroller can
wake up the transceiver (switch to normal operating mode)
via STB and EN.

To prevent false wake-up due to transients or RF fields,
wake-up voltage threshold levels have to be maintained
for a certain period of time. In the low power modes the
failure detection circuit remains partly active to prevent
increased power consumption should errors 3, 4 and 7
occur.

Power on

After power-on V

is switched on, the INH pin will

BAT

become HIGH and an internal power-on flag will be set.
This flag can be read via the NERR pin (STB = 1, EN = 0)
and will be reset by entering the normal operation mode.

Table 1 Truth table of CAN transceiver

The EN and

STB pins will internally be set to LOW level, if
the VCC voltage is below a certain threshold level, to
provide fail safe functionality.

Protections

A current limiting circuit protects the transmitter output
stages against short-circuit to positive and negative
battery voltage.

If the junction temperature exceeds a maximum value, the
transmitter output stages are disabled. Because the
transmitter is responsible for the major part of the power
dissipation, this will result in a reduced power dissipation
and hence a lower chip temperature. All other parts of the
IC will remain operating.

The CANH and CANL inputs are protected against
electrical transients which may occur in an automotive
environment.

SOLDERING
Introduction

There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.

This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

“IC Package Databook”

Reflow soldering

Reflow soldering techniques are suitable for all SO
packages.

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.

(order code 9398 652 90011).

Wave soldering

Wave soldering techniques can be used for all SO
packages if the following conditions are observed:

• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.

• The longitudinal axis of the package footprint must be
parallel to the solder flow.

• The package footprint must incorporate solder thieves at
the downstream end.

During placement and before soldering, the package must
be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.

A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

Repairing soldered joints

Fix the component by first soldering two diagonally­opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
