Infineon TLE7209-2R is also very similar, but adds SPI and changes the behavior of a couple of input pins. I haven't checked thoroughly if the differences in pinout could be worked around on the board.

https://www.mouser.com/ProductDetail...kA%252b45AQ%3d


Also, I've attached a datasheet for the Bosch CJ220 H-bridge, which is evidently the same as the 30348.

It is suppose to be a replacement for the Freescale

awesome! where would you find this other than ebay?

I checked mouser and didnt see it when i searched for "Bosch 30348"

i want to make sure i get a good verison not a chinese clone.

i am very happy you found a good alternative, i want to this myself. I had plans to send out my DME to a well known person but he is so backed up my friends have been waiting for 6+ months to get MS45.1 EWS Delete DMEs back id love to just do this myself now.

i have 2 spare MSS54HP Dmes to practice on so nows as a good as time as ever especially since it seems the chips that are needed to perform this function seem to go out of stock permanently often or superceded often.

I cant seem to find any chips that say:
Bosch
30348 0417
8409SLS
50EE02


does the only thing that matter is just the 30348 part?

i found this one on ebay, refurbished unit but its not from China. does anyone think it would work?

ok dokie well just taking a chance and went ahead and ordered 2 of the 30348 chips in the mentioned ebay link.

also ordered a few sets of

AVX TPSD156K035R0100
AVX 581-08055C104J4T2A X 2

extras in case i mess anything up or lose something.

about to order the CSL flap itself and the plug connector as well to have on hand for testing and installation.

will cross fingers and hope all goes well.

Default Re: Converting an MSS54HP into an MSS54HP CSL (H-bridge)

I finally got around to taking my spare MS S54 HP DME and try my hand at soldering this h bridge and capacitors.

So the h bridge initially I was having problems with heat as terraphantm had mentioned a few pages ago. I was kind of getting frustrated because I thought I cranked up the heat all the way but apparently I didn't only at 280 degrees. And I had my fan speed turned down Al the way. I forgot this thing even had fan speed on it but apparently I had it adjusted really low because I was using it for cluster chips and I guess the fan speed was blowing the chip off the board at that time lol.

so anyways I turned up the temperature to 480 which was the max it could go and I turned up the fan speed to about 80% and once I did that I was getting the heat in the flow I was looking for on the feet pads... Finally the sorrow was starting to flow and the flux was starting to dissipate.

I was able to use a toothpick right in the center of the chip and kind of add just a hair of pressure as I heated up the chip around the feet and the center of the chip to get the solder underneath to flow and sandwich between the chip and the board and it worked the chips settle down a little bit more and the solder seemed to flow.

I actually had more problems trying to solder on the capacitors on the back of the board because no matter what type of heat and fan speed I used I could not get the solder pads to flow well at all. If I cranked up the heat and the fan speed up enough it was actually burning or charring the large brown capacitor so I ended up taking another capacitor brand new and using my soldering tip and putting a little bit of solder on each side and rested in place on top of the pads and using the soldering tip to kind of melt and flow the solder as best I could.

Same thing for those little capacitors... pretty hard because I didn't have any tips that were small enough that actually maintained the heat The smaller tip I went the less heat they seem to put out I can only get more heat from the larger tips.

But I got everything on. the large capacitor on the back isn't the prettiest but I used a continuity tester and tested continuity from the h bridge on one side to one side of each of the capacitors to make sure that they were getting continuity. Is there a term for bubble gum solder

I ordered my CSL intake flap from ECS it'll be here Thursday so hopefully by the weekend I'll be able to test and see if the flap works.

I'm assuming that if I fried the board the DME would just be toast right?

Or would the DME be okay and just a flap control would be toast?

Anyway here are some pictures if anybody cares.

It was my first time working with something this tough In regards to heat control don't laugh.

That H bridge looks pretty well soldered. Although personally I’d have left the heat sinking solder off first to ensure it works properly before you anchor it down so to speak!

The caps on the back are easier done with a soldering iron over heat.

Just remember you have to run the flap test twice before it works - no one knows why that is ����*♂️

what do you need to run the flap test?
