2003 oct 22 4 philips semiconductors product speci?cation high speed can transceiver tja1050 functional description the tja1050 is the interface between the can protocol controller and the physical bus. it is primarily intended for high-speed automotive applications using baud rates from 60 kbaud up to 1 mbaud. it provides differential transmit capability to the bus and differential receiver capability to the can protocol controller. it is fully compatible to the iso 11898 standard. a current-limiting circuit protects the transmitter output stage from damage caused by accidental short-circuit to either positive or negative supply voltage, although power dissipation increases during this fault condition. a thermal protection circuit protects the ic from damage by switching off the transmitter if the junction temperature exceeds a value of approximately 165 c. because the transmitter dissipates most of the power, the power dissipation and temperature of the ic is reduced. all other ic functions continue to operate. the transmitter off-state resets when pin txd goes high. the thermal protection circuit is particularly needed when a bus line short-circuits. the pins canh and canl are protected from automotive electrical transients (according to iso 7637 ; see fig.4). control pin s allows two operating modes to be selected: high-speed mode or silent mode. the high-speed mode is the normal operating mode and is selected by connecting pin s to ground. it is the default mode if pin s is not connected. however, to ensure emi performance in applications using only the high-speed mode, it is recommended that pin s is connected to ground. in the silent mode, the transmitter is disabled. all other ic functions continue to operate. the silent mode is selected by connecting pin s to v cc and can be used to prevent network communication from being blocked, due to a can controller which is out of control. a txd dominant time-out timer circuit prevents the bus lines being driven to a permanent dominant state (blocking all network communication) if pin txd is forced permanently low by a hardware and/or software application failure. the timer is triggered by a negative edge on pin txd. if the duration of the low-level on pin txd exceeds the internal timer value, the transmitter is disabled, driving the bus into a recessive state. the timer is reset by a positive edge on pin txd. table 1 function table of the can transceiver; x = dont care v cc txd s canh canl bus state rxd 4.75 v to 5.25 v low low (or ?oating) high low dominant low 4.75 v to 5.25 v x high 0.5v cc 0.5v cc recessive high 4.75 v to 5.25 v high (or ?oating) x 0.5v cc 0.5v cc recessive high <2 v (not powered) x x 0 v < v canh 2 v x 0 v < v canh 2003 oct 22 5 philips semiconductors product speci?cation high speed can transceiver tja1050 limiting values in accordance with the absolute maximum rating system (iec 60134). all voltages are referenced to gnd (pin 2). positive currents ?ow into the ic. notes 1. the waveforms of the applied transients shall be in accordance with iso 7637 part 1 , test pulses 1, 2, 3a and 3b (see fig.4). 2. human body model: c = 100 pf and r = 1.5 k w . 3. machine model: c = 200 pf, r = 10 w and l = 0.75 m h. 4. in accordance with iec 60747-1 . an alternative definition of t vj is: t vj =t amb +p r th(vj-a) , where r th(vj-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) and ambient temperature (t amb ). thermal characteristics according to iec 60747-1. quality specification quality specification snw-fq-611 part d is applicable. symbol parameter conditions min. max. unit v cc supply voltage - 0.3 +6 v v canh dc voltage at pin canh 0 < v cc < 5.25 v; no time limit - 27 +40 v v canl dc voltage at pin canl 0 < v cc < 5.25 v; no time limit - 27 +40 v v txd dc voltage at pin txd - 0.3 v cc + 0.3 v v rxd dc voltage at pin rxd - 0.3 v cc + 0.3 v v ref dc voltage at pin v ref - 0.3 v cc + 0.3 v v s dc voltage at pin s - 0.3 v cc + 0.3 v v trt(canh) transient voltage at pin canh note 1 - 200 +200 v v trt(canl) transient voltage at pin canl note 1 - 200 +200 v v esd electrostatic discharge voltage at all pins note 2 - 4000 +4000 v note 3 - 200 +200 v t stg storage temperature - 55 +150 c t vj virtual junction temperature note 4 - 40 +150 c symbol parameter conditions value unit r th(vj-a) thermal resistance from junction to ambient in so8 package in free air 145 k/w r th(vj-s) thermal resistance from junction to substrate of bare die in free air 50 k/w

2003 oct 22 15 philips semiconductors product speci?cation high speed can transceiver tja1050 soldering introduction to soldering surface mount packages 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 surface mount ic packages. wave soldering can still be used for certain surface mount ics, but it is not suitable for fine pitch smds. in these situations reflow soldering is recommended. re?ow 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. driven by legislation and environmental forces the worldwide use of lead-free solder pastes is increasing. several methods exist for reflowing; for example, convection or convection/infrared 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 270 c depending on solder paste material. the top-surface temperature of the packages should preferably be kept: below 220 c (snpb process) or below 245 c (pb-free process) C for all bga and ssop-t packages C for packages with a thickness 3 2.5 mm C for packages with a thickness < 2.5 mm and a volume 3 350 mm 3 so called thick/large packages. below 235 c (snpb process) or below 260 c (pb-free process) for packages with a thickness < 2.5 mm and a volume < 350 mm 3 so called small/thin packages. moisture sensitivity precautions, as indicated on packing, must be respected at all times. wave 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): C 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; C 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 of the leads in the wave ranges from 3 to 4 seconds at 250 c or 265 c, depending on solder material applied, snpb or pb-free respectively. a mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. manual 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.
2003 oct 22 16 philips semiconductors product speci?cation high speed can transceiver tja1050 suitability of surface mount ic packages for wave and re?ow soldering methods notes 1. for more detailed information on the bga packages refer to the (lf)bga application note (an01026); order a copy from your philips semiconductors sales office. 2. 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 . 3. these transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature exceeding 217 c 10 c measured in the atmosphere of the reflow oven. the package body peak temperature must be kept as low as possible. 4. these packages are not suitable for wave soldering. on versions with the heatsink on the bottom side, the solder cannot penetrate between the printed-circuit board and the heatsink. on versions with the heatsink on the top side, the solder might be deposited on the heatsink surface. 5. 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. 6. wave soldering is suitable for lqfp, tqfp and qfp packages with a pitch (e) larger than 0.8 mm; it is definitely not suitable for packages with a pitch (e) equal to or smaller than 0.65 mm. 7. wave soldering is suitable for ssop, tssop, vso and vssop 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. 8. hot bar or manual soldering is suitable for pmfp packages. revision history package (1) soldering method wave reflow (2) bga, lbga, lfbga, sqfp, ssop-t (3) , tfbga, vfbga not suitable suitable dhvqfn, hbcc, hbga, hlqfp, hsqfp, hsop, htqfp, htssop, hvqfn, hvson, sms not suitable (4) suitable plcc (5) , so, soj suitable suitable lqfp, qfp, tqfp not recommended (5)(6) suitable ssop, tssop, vso, vssop not recommended (7) suitable pmfp (8) not suitable not suitable rev date cpcn description 4 20031013 - product speci?cation (9397 750 12157) modi?cation: added recommendation to connect unused pin s to ground added chapter revision history 3 20020516 - product speci?cation (9397 750 09778)
