Great job!
I hope i can get some help here.
I have the same backflip and my issue is the spring that rotates the whole thing. I cant figure the proper way to put it back together. Do you maybe have some more photos of it ?

Thanks in advance.

In reply to Ivo.

You only almost downloaded the datasheet of this pwm chip Ivo?
In case you did find more about this ic please share it with Jestine! So he can provide it to us.

In reply to Michel Janssen.

Sorry for my late reply Michael. I hardly ever check my older repairs on any new posts added by new readers. And you maybe already bought these by now from a seller online?
But if you still do need a couple of them I am happy to provide them as long as you pay for postage and cost of parts. I can't give you my email address or other info here but maybe you can ask Jestine. I'm almost sure he can help to provide that information if you still need a few of these 6 pin pwm ic's.

Hi, this information was very useful to me. I also have a Bosch charger for an electric scooter battery filled with this chip. Although I almost downloaded the circuit of this chip, thank you very much for this information and success in future endeavors.

Goedemiddag Mr. van Bemmelen,

Bedankt voor de fijne tips, zelf was ik privé met een Bosch batterijlader aan het worstelen met hetzelfde Melexis ic die het liet afweten. De transistor TSC13003 en 10 ohm weerstand zijn natuurlijk ook naar het hiernamaals.
Indien u een paar van deze ic-tjes zou willen verkopen dan ben ik natuurlijk geïnteresseerd.
Dank bij voorbaat, met vriendelijke groeten,
Michel.
====================================

Good afternoon Mr. van Bemmelen,

Thanks for the great tips, I was privately struggling with a Bosch battery charger with the same Melexis ic that failed. The transistor TSC13003 and 10 ohm resistor are of course also to the afterlife.
If you would like to sell a few of these ICs then I am of course interested.
Thanks in advance, best regards,
Michel.

In reply to Yogesh Panchal.

Indeed Yogesh, but a datasheet of the missing specs of the mlx02367A would have made it so much easier!

Albert,
Making stagewise diagram is always useful to understand the working of the section.Here 67A PWM IC is taking feedback signal from opto and supplying it to the switching section....and you can easily trace the culprit.

Looking forward to learn this new trick
