PCA82C250
FUNCTIONAL DESCRIPTION
The PCA82C250 is the interface between the CAN
protocol controller and the physical bus. It is primarily
intended for high-speed applications (up to 1 Mbaud) in
cars. The device provides differential transmit capability to
the bus and differential receive capability to the CAN
controller. It is fully compatible with the
"ISO 11898"
standard.
A current limiting circuit protects the transmitter output
stage against short-circuit to positive and negative battery
voltage. Although the power dissipation is increased
during this fault condition, this feature will prevent
destruction of the transmitter output stage.
If the junction temperature exceeds a value of
approximately 160
°
C, the limiting current of both
transmitter outputs is decreased. 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
in operation. The thermal protection is particularly needed
when a bus line is short-circuited.
The CANH and CANL lines are also protected against
electrical transients which may occur in an automotive
environment.
Pin 8 (Rs) allows three different modes of operation to be
selected: high-speed, slope control or standby.
For high-speed operation, the transmitter output
transistors are simply switched on and off as fast as
possible. In this mode, no measures are taken to limit the
rise and fall slope. Use of a shielded cable is
recommended to avoid RFI problems. The high-speed
mode is selected by connecting pin 8 to ground.
For lower speeds or shorter bus length, an unshielded
twisted pair or a parallel pair of wires can be used for the
bus. To reduce RFI, the rise and fall slope should be
limited. The rise and fall slope can be programmed with a
resistor connected from pin 8 to ground. The slope is
proportional to the current output at pin 8.
If a HIGH level is applied to pin 8, the circuit enters a low
current standby mode. In this mode, the transmitter is
switched off and the receiver is switched to a low current.
If dominant bits are detected (differential bus voltage
>0.9 V), RXD will be switched to a LOW level.
The microcontroller should react to this condition by
switching the transceiver back to normal operation (via
pin 8). Because the receiver is slow in standby mode, the
first message will be lost.

LIMITING VALUES
In accordance with the Absolute Maximum Rating System (IEC 60134); all voltages are referenced to pin 2;
positive input current.
Notes
1. In accordance with
"IEC 60747-1". An alternative definition of virtual junction temperature is:
T
vj
= T
amb
+ P
d
×
R
th(vj-a)
, where R
th(j-a)
is a fixed value to be used for the calculation of T
vj
. The rating for T
vj
limits
the allowable combinations of power dissipation (P
d
) and ambient temperature (T
amb
).

SOLDERING
Introduction
This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our
"Data Handbook IC26; Integrated Circuit Packages"
(document order number 9398 652 90011).
There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mount components are mixed on
one printed-circuit board. However, wave soldering is not
always suitable for surface mount ICs, or for printed-circuit
boards with high population densities. In these situations
reflow soldering is often used.
Through-hole mount packages
S
OLDERING BY DIPPING OR BY SOLDER WAVE
The maximum permissible temperature of the solder is
260
°
C; solder at this temperature must not be in contact
with the joints for more than 5 seconds. The total contact
time of successive solder waves must not exceed
5 seconds.
The device may be mounted up to the seating plane, but
the temperature of the plastic body must not exceed the
specified maximum storage temperature (T
stg(max)
). If the
printed-circuit board has been pre-heated, forced cooling
may be necessary immediately after soldering to keep the
temperature within the permissible limit.
M
ANUAL SOLDERING
Apply the soldering iron (24 V or less) to the lead(s) of the
package, either below the seating plane or not more than
2 mm above it. If the temperature of the soldering iron bit
is less than 300
°
C it may remain in contact for up to
10 seconds. If the bit temperature is between
300 and 400
°
C, contact may be up to 5 seconds.
Surface mount packages
R
EFLOW SOLDERING
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 methods exist for reflowing; for example,
infrared/convection heating in a conveyor type oven.
Throughput times (preheating, soldering and cooling) vary
between 100 and 200 seconds depending on heating
method.
Typical reflow peak temperatures range from
215 to 250
°
C. The top-surface temperature of the
packages should preferable be kept below 230
°
C.
W
AVE SOLDERING
Conventional single wave soldering is not recommended
for surface mount devices (SMDs) or printed-circuit boards
with a high component density, as solder bridging and
non-wetting can present major problems.
To overcome these problems the double-wave soldering
method was specifically developed.
If wave soldering is used the following conditions must be
observed for optimal results:
·
Use a double-wave soldering method comprising a
turbulent wave with high upward pressure followed by a
smooth laminar wave.
·
For packages with leads on two sides and a pitch (e):
­ larger than or equal to 1.27 mm, the footprint
longitudinal axis is preferred to be parallel to the
transport direction of the printed-circuit board;
­ smaller than 1.27 mm, the footprint longitudinal axis
must be parallel to the transport direction of the
printed-circuit board.
The footprint must incorporate solder thieves at the
downstream end.
·
For packages with leads on four sides, the footprint must
be placed at a 45
°
angle to the transport direction of the
printed-circuit board. The footprint must incorporate
solder thieves downstream and at the side corners.
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.
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.
M
ANUAL SOLDERING
Fix the component by first soldering two
diagonally-opposite end leads. Use a low voltage (24 V or
less) soldering iron 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.

Suitability of IC packages for wave, reflow and dipping soldering methods
Notes
1. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum
temperature (with respect to time) and body size of the package, there is a risk that internal or external package
cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the
Drypack information in the
"Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods".
2. For SDIP packages, the longitudinal axis must be parallel to the transport direction of the printed-circuit board.
3. These packages are not suitable for wave soldering as a solder joint between the printed-circuit board and heatsink
(at bottom version) can not be achieved, and as solder may stick to the heatsink (on top version).
4. If wave soldering is considered, then the package must be placed at a 45
°
angle to the solder wave direction.
The package footprint must incorporate solder thieves downstream and at the side corners.
5. Wave soldering is only suitable for LQFP, QFP and TQFP packages with a pitch (e) equal to or larger than 0.8 mm;
it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm.
6. Wave soldering is only suitable for SSOP and TSSOP packages with a pitch (e) equal to or larger than 0.65 mm; it is
definitely not suitable for packages with a pitch (e) equal to or smaller than 0.5 mm.
