Yup Zulu I found that chart but sadly I'm not an electrical guy , I'm a chemical engineer with no job

I'll try to get the same part and take it to someone to solder it .

Thanks a lot Zulu for your help..

pmt I have two questions .
Did you disconnect the circuit board or did you welded the new ic while it's still attached to the plastic frame?
I'm afraid I will break something underneath if I force lifting it.

2nd here is the link to the website has the IC
MC33286DW datasheet pdf,MC33286DW supplier,MC33286DW price,MC33286DW picture at UTSOURCE
but I'm not sure which one should I get is MC33286DWR2 is the same as MC33286DW ?

Thanks in advance

The circuit board is soldered directly to the motor power contacts, so it can't be removed from the assembly without desoldering. I fixed it while it was still attached to the motor with no issues.

I believe that MC33286DW and MC33826DWR2 are equivalent. I think the R2 is just a later revision.

Back when I did this in 2008, I could not find a source for MC33286DW in quantities less than 100 and had to go for the MC33289DW from digi-key for about $4. I hope this site you found works out for you.

Also, if you're taking it to an electronics repair place to have it soldered, they may also be able to get the MC33286DW from their suppliers -- may be worth asking them.

Let us know how it goes...

pmt thanks a lot for your replay I ordered two of those ICs just in case, It will take two weeks to get them in the mail. the sad point I'm not able to find someone to do the soldering for me close to chicago. I will let you know how it will go.
thanks again

How much did you end up paying for the ICs, if you don't mind sharing?

There should be plenty of places that could solder that for you. Check on the web or on Craiglist for "electronics repair" or "video game console repair" -- most of those guys that fix xbox and PS3 problems would have the necessary skills and equipment to do something like this. ...and there are plently of them.

I paid 5 bucks for each plus $4 for shipping so total of $14

I will try finding someone solder it for me and I will let you know ,
